Pairing a smaller rotary screw compressor with an air receiver tank cost-effectively meets peak demand spikes without oversizing. Larger compressed air systems may have both primary and secondary receivers.<\/p>\n<h4>What are Air (gas) bearings?<\/h4>\n<p>Hydrostatic or hydrodynamic machine elements can carry loads due to high pressure. Bearings allow a degree of movement with air (or other gas) acting as a lubricant.<\/p>\n<h4>What is aftercooler?<\/h4>\n<p>A heat exchange device that cools the exhaust air after compression. After cooling, any resulting condensate can be removed using a moisture separator.<\/p>\n<h4>What is Automatic sequencer?<\/h4>\n<p>A control device or tool programmed to operate air compressors in a predetermined sequence.<\/p>\n<h4>What is brake horsepower (bhp)?<\/h4>\n<p>The horsepower required at the input shaft of the compressor for proper performance.<\/p>\n<h4>What is capacity gauge?<\/h4>\n<p>This tool is used to measure the amount of airflow inside rotary screw compressors. Results are usually displayed as a percentage of capacity.<\/p>\n<h4>What is check valve?<\/h4>\n<p>A check valve is a device used to allow a one-way flow of air inside the compressor. It permits airflow in one direction while preventing backflow or reverse flow in the opposite direction.<\/p>\n<h4>What is compression ratio?<\/h4>\n<p>Expresses the ratio between inlet absolute pressure and discharge absolute pressure. The critical pressure ratio defines the point at which gas flow reaches sonic velocity, capping maximum flow rate regardless of further pressure increase.<\/p>\n<h4>What does &#8220;bar&#8221; mean on an air compressor?<\/h4>\n<p>Bar is a metric unit of pressure equal to 100,000 pascals, roughly matching atmospheric pressure at sea level (about 14.5 psi). It appears on compressor gauges and spec sheets, especially outside the United States, to indicate tank or discharge pressure. When comparing equipment internationally, converting bar to psi ensures accurate comparisons between compressor models and specifications.<\/p>\n<h4>What is CFM ?<\/h4>\n<p><a href=\"https:\/\/bisoncompressor.com\/blog\/air-compressor-cfm\/\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/bisoncompressor.com\/wp-content\/uploads\/2023\/05\/air-compressor-cfm.jpg\" alt=\"\" width=\"800\" height=\"491\" title=\"\"><\/a><\/p>\n<p><a href=\"https:\/\/bisoncompressor.com\/blog\/air-compressor-cfm\/\" target=\"_blank\" rel=\"noopener\">CFM<\/a> stands for Cubic Feet per Minute. It is a unit of measurement used to quantify the volumetric flow rate of air or gas, indicating how much air passes through a specific point within one minute. CFM is commonly used to assess air compressor capacity and performance. Air delivery is measured via the low pressure orifice test method, recognized by ASME and ANSI standards.<\/p>\n<h4>What is Free Air CFM?<\/h4>\n<p>The airflow rate at a specified point and condition is then converted to ambient conditions.<\/p>\n<h4>What is Actual CFM?<\/h4>\n<p>Air flow rate at a specified point and conditions, using standardized testing and certification methods to ensure consistent, comparable results.<\/p>\n<h4>What is Inlet CFM ?<\/h4>\n<p>The air that flows through the inlet filter or valve of the compressor (under rated conditions).<\/p>\n<h4>What is Standard CFM?<\/h4>\n<p>Free airflow measured and converted to uniform reference conditions (68\u00b0F, 0% humidity, 14.5 psia). ACFM measures airflow at the specific measurement point; SCFM normalizes to standardized conditions for consistent comparison across compressors.<\/p>\n<h4>What is Cut-in pressure?<\/h4>\n<p>The minimum discharge pressure that, when reached, switches the compressor from unload to load operation.<\/p>\n<h4>What is Cutout pressure?<\/h4>\n<p>The maximum discharge pressure that, when reached, switches the compressor to unload.<\/p>\n<h4>What is Duty Cycle?<\/h4>\n<p><a href=\"https:\/\/bisoncompressor.com\/blog\/air-compressor-duty-cycles\/\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/bisoncompressor.com\/wp-content\/uploads\/2023\/03\/air-compressor-duty-cycles-1024x585.jpg\" alt=\"\" width=\"800\" height=\"457\" title=\"\"><\/a><\/p>\n<p>The <a href=\"https:\/\/bisoncompressor.com\/blog\/air-compressor-duty-cycles\/\" target=\"_blank\" rel=\"noopener\">air compressor duty cycle<\/a> refers to the length of time the machine can continue to operate within a specified period of time, usually expressed as a percentage.<br>This directly affects running time and cooling time. Different compressor types have greatly different duty cycles\u2014a key factor for long-term efficient operation and service life. Operating beyond the specified cycle causes overheating and early wear. A 50% duty cycle unit must rest half the time to avoid overheating, unlike 100% continuous-duty units. Secondary specs like voltage, phase, tank size, and noise level also vary and should be checked against duty cycle rating.<\/p>\n<h4>What is Desiccant?<\/h4>\n<p>A material with a very porous surface that can draw in water vapour from the surrounding air and then remove it.<\/p>\n<h4>What is Dew point?<\/h4>\n<p>The temperature at which moisture begins to condense if air cools at constant pressure. Water content in compressed air is quantified by dew point or ppm; inadequate control causes corrosion and downstream equipment damage.<\/p>\n<h4>What is Diaphragm?<\/h4>\n<p>A flexible membrane that separates the compression chamber from the drive mechanism in diaphragm-type compressors, used to move or compress air without leakage. Also refers to a flexible element in pneumatic control valves. (Note: In centrifugal compressors, &#8220;diaphragm&#8221; can refer to a static component between stages that may include guide vanes, but this is not applicable to most reciprocating or rotary screw compressors.)<\/p>\n<h4>What is Diaphragm cooling?<\/h4>\n<p>A heat removal method that circulates coolant through the diaphragm.<\/p>\n<h4>Displacement<\/h4>\n<p>Expressed in cfm or cubic centimeters, this is the volume displaced by the piston or rotor.<\/p>\n<h4>Compression efficiency<\/h4>\n<p>Compares the theoretical power to the power delivered to the air or gas by the compressor.<\/p>\n<h4>Isothermal efficiency<\/h4>\n<p>Compares the theoretical work to the actual work transferred to the gas during compression.<\/p>\n<h4>Mechanical efficiency<\/h4>\n<p>Compares power delivered (from air or gas) to brake horsepower.<\/p>\n<h4>Polytropic efficiency<\/h4>\n<p>Compares polytropic energy transferred to gas versus actual transferable energy. The polytropic process follows PV^n=constant, where exponent n varies with heat transfer during compression, distinguishing it from ideal isothermal or adiabatic models.<\/p>\n<h4>Volumetric efficiency<\/h4>\n<p>Compares the compressor\u2019s actual capacity to its piston displacement.<\/p>\n<h4>What is Exhauster?<\/h4>\n<p>A compressor whose inlet pressure is lower than its atmospheric pressure.<\/p>\n<h4>What are Expanders?<\/h4>\n<p>Engines or turbines in which the expanding gas works and then undergoes a temperature drop.<\/p>\n<h4>What are Air compressor Filters?<\/h4>\n<p><a href=\"https:\/\/bisoncompressor.com\/blog\/how-to-avoid-microorganisms-in-compressed-air\/\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/bisoncompressor.com\/wp-content\/uploads\/2023\/09\/air-compressor-filter.jpg\" alt=\"\" width=\"841\" height=\"556\" title=\"\"><\/a><\/p>\n<p><a href=\"https:\/\/bisoncompressor.com\/air-compressor-air-filter\/\" target=\"_blank\" rel=\"noopener\">Air compressor filter<\/a> is a device used to remove moisture, particles and lubricants from the surrounding air.&nbsp;ISO 8573 is the international standard for compressed air quality classification. Medical air requires strict purity standards\u2014oil-free, low-contaminant compressed air for hospital and dental applications.<\/p>\n<h4>Free air<\/h4>\n<p>Refers to atmospheric air that is not affected by the compressor.<\/p>\n<h4>Full load<\/h4>\n<p>Refers to the full-speed operation of an air compressor, providing the maximum airflow through a wide-open inlet and discharge.<\/p>\n<h4>Gauge pressure<\/h4>\n<p>It\u2019s usually expressed in pounds per square inch (psig).

A variable frequency drive (VFD) adjusts motor speed to match real-time air demand rather than running at fixed speed, improving energy efficiency.<\/p>\n<h4>What is Piston displacement?<\/h4>\n<p>The volume of air displaced by the piston. The first-stage piston displacement is the overall piston displacement for multistage compressors.<\/p>\n<h4>What is Pneumatic tools?<\/h4>\n<p>Special tools powered by compressed air.&nbsp;Most air tools require around 90 PSI, but heavy-duty applications may demand 100-150 PSI or higher.<\/p>\n<h4>What is Polytropic head?<\/h4>\n<p>Expressed in foot-pounds (ft. lbs.), this is the energy required to compress air polytropically (reversibly) to move one pound of gas from one pressure to another.<\/p>\n<h4>Pressure drop<\/h4>\n<p>It means pressure loss in a compressed air system due to restriction or friction.&nbsp;Pressure loss in a compressed air system due to restriction or friction. Equivalent pipe length accounts for fittings and valves by expressing them as additional straight-pipe length for more accurate pressure drop calculations. Reynolds&#8217; number determines whether airflow in piping is laminar or turbulent.<\/p>\n<h4>Relative humidity<\/h4>\n<p>The comparison between the partial pressure of a vapor and its saturation pressure at the dry-bulb temperature.<\/p>\n<h4>Rotor<\/h4>\n<p>A compressor rotating element consisting of one or more impellers and shafts in moving compressors.<\/p>\n<h4>What is Specific humidity?<\/h4>\n<p>In a mixture of air vapor, it is the weight of water vapor per pound of dry air.<\/p>\n<h4>What is Standard air?<\/h4>\n<p>Defined in ISO standards as 68\u00b0F (20\u00b0C), dry (0% relative humidity), and 14.5 psia. The Normal Litre standardizes gas volume measurement at 0\u00b0C and 1 atm for consistent comparison of air consumption across compressor systems.<\/p>\n<h4>What is Static temperature?<\/h4>\n<p>Static temperature: The temperature of a gas measured by a thermometer that is stationary relative to the gas flow (i.e., moving with the gas). It represents the actual thermodynamic temperature of the gas, excluding the kinetic energy of the flow.<\/p>\n<h4>Temperature rise ratio<\/h4>\n<p>Comparison between the temperature rise and the total temperature rise during the compression process. For a perfect gas, it is equal to the ratio of the actual increase in enthalpy to the rise in isentropic enthalpy.<\/p>\n<h4>Theoretical (ideal) horsepower<\/h4>\n<p>The amount of horsepower required to isolate gas or air under specified conditions.<\/p>\n<h4>What are Vacuum pumps?<\/h4>\n<p><a href=\"https:\/\/bisoncompressor.com\/air-compressor-pump\/\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/bisoncompressor.com\/wp-content\/uploads\/2023\/02\/air-compressor-pump-2-1024x866.jpg\" alt=\"\" width=\"800\" height=\"677\" title=\"\"><\/a><\/p>\n<p>Various compressors operate with a volume below atmospheric pressure and discharge at or above that pressure.<\/p>\n<h4>What is Valves?<\/h4>\n<p>Devices are used to direct or stop airflow within a system.<\/p>\n<h4>Water-cooled compressor<\/h4>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/bisoncompressor.com\/wp-content\/uploads\/2023\/07\/air-cool-vs-water-cool-compressor.png\" alt=\"\" width=\"1024\" height=\"576\" title=\"\"><\/p>\n<p>A water-cooled compressor that is cooled by water circulation through jackets near the cylinder, or casing, between and after the compression stages. Water cooling is more efficient than air cooling for high-capacity, continuous-duty industrial compressors, as it handles sustained thermal loads better. Requires access to water supply and drainage, making it suited to stationary industrial installations rather than portable shop setups.<\/p>\n<h2>Reciprocating vs Rotary Screw Compressors<\/h2>\n<p>The two dominant mechanisms found in most air compressor terminology are reciprocating (piston) and rotary screw designs. Understanding the distinction helps make sense of many other terms in this glossary, since specifications like duty cycle, displacement, and compression ratio behave differently depending on which mechanism is being described.<\/p>\n<p>Reciprocating (piston) compressors use one or more pistons driven by a crankshaft to compress air inside a cylinder, similar in principle to a pump. Common variants include:<\/p>\n<ul>\n<li>Single-stage \u2014 compresses air to final pressure in one piston stroke; typically used for lower-pressure applications.<\/li>\n<li>Two-stage \u2014 compresses air across two strokes with intercooling between stages, allowing higher pressures with less heat buildup, making them suited to more demanding tasks than single-stage units.<\/li>\n<li>Oil-lubricated \u2014 uses oil to lubricate the piston and cylinder, generally supporting longer duty cycles.<\/li>\n<li>Oil-free (oil-less) \u2014 uses self-lubricating materials instead of oil, reducing the risk of oil contamination in the air supply.<\/li>\n<li>Double acting \u2014 compresses air on both sides of the piston during each stroke cycle, effectively doubling output capacity compared to single-acting designs.<\/li>\n<\/ul>\n<p>Rotary screw compressors use two interlocking helical rotors that compress air continuously as they turn, rather than in discrete strokes. Variants include:<\/p>\n<ul>\n<li>Oil-injected \u2014 oil is injected into the compression chamber for lubrication, sealing, and cooling; oil-flooded designs use continuous oil circulation for enhanced cooling and sealing performance.<\/li>\n<li>Oil-free \u2014 rotors are precision-machined to compress air without oil contact in the compression chamber, eliminating oil from the compression chamber entirely, which makes them essential for food, pharmaceutical, and electronics manufacturing where contamination is unacceptable.<\/li>\n<li>Fixed-speed \u2014 runs at a constant motor speed regardless of demand.<\/li>\n<li>Variable-speed drive (VSD) \u2014 adjusts motor speed to match air demand, which can reduce energy use during partial-load operation.<\/li>\n<\/ul>\n<table>\n<tbody>\n<tr>\n<th>Feature<\/th>\n<th>Reciprocating<\/th>\n<th>Rotary Screw<\/th>\n<\/tr>\n<tr>\n<td>Compression action<\/td>\n<td>Intermittent (piston strokes)<\/td>\n<td>Continuous (rotating screws)<\/td>\n<\/tr>\n<tr>\n<td>Typical duty cycle<\/td>\n<td>Lower, suited to intermittent use<\/td>\n<td>Higher, suited to continuous use<\/td>\n<\/tr>\n<tr>\n<td>Noise\/vibration<\/td>\n<td>Generally higher<\/td>\n<td>Generally lower<\/td>\n<\/tr>\n<tr>\n<td>Common lubrication<\/td>\n<td>Oil-lubricated or oil-free<\/td>\n<td>Oil-injected or oil-free<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>In conclusion<\/h2>\n<p>As a professional <a href=\"https:\/\/bisoncompressor.com\/air-compressor\/\" target=\"_blank\" rel=\"noopener\">air compressor manufacturer<\/a>, BISON knows that this terminology guide may not cover all professional terms.

A small at-home compressor delivers about 2 CFM; industrial units with 200 HP achieve roughly 1,000 CFM at 100 PSI. As a rule of thumb, a well-designed compressor produces about 4 CFM at 100 PSIG per horsepower. If a compressor&#8217;s rated CFM falls short of that ratio relative to horsepower, the motor may be oversized, wasting energy rather than boosting performance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-2101\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"2\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-2101\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><h3 class=\"e-n-accordion-item-title-text\"> What is 1 CFM? <\/h3><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-minus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-plus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2101\" class=\"elementor-element elementor-element-3254bddc e-con-full e-flex e-con e-child\" data-id=\"3254bddc\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3cd3c7a2 elementor-widget elementor-widget-text-editor\" data-id=\"3cd3c7a2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">A cubic foot is 28.3 liters. 1 CFM is a flow rate of 28.3 liters per minute.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t<details id=\"e-n-accordion-item-2102\" class=\"e-n-accordion-item\" >\n\t\t\t\t<summary class=\"e-n-accordion-item-title\" data-accordion-index=\"3\" tabindex=\"-1\" aria-expanded=\"false\" aria-controls=\"e-n-accordion-item-2102\" >\n\t\t\t\t\t<span class='e-n-accordion-item-title-header'><h3 class=\"e-n-accordion-item-title-text\"> How to read air compressor specs? <\/h3><\/span>\n\t\t\t\t\t\t\t<span class='e-n-accordion-item-title-icon'>\n\t\t\t<span class='e-opened' ><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-minus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t<span class='e-closed'><svg aria-hidden=\"true\" class=\"e-font-icon-svg e-fas-plus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t<div role=\"region\" aria-labelledby=\"e-n-accordion-item-2102\" class=\"elementor-element elementor-element-50f96cec e-con-full e-flex e-con e-child\" data-id=\"50f96cec\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-69b237a0 elementor-widget elementor-widget-text-editor\" data-id=\"69b237a0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Focus on matching CFM to PSI together, not separately, since airflow output changes with pressure.
