Air Compressor Parts Guide

Air compressors are essential power sources for many businesses and have a wide variety of applications. From startup and shutdown in an auto repair shop to 24-hour daily operation in an industrial environment, air compression is a standard business process that needs to be efficient.

Air compressors can work hard depending on your environment, so the inner workings of your air supply system must be well maintained to benefit your business productivity and profitability. Each part has a specific function. If these parts are not properly maintained, it can affect air supply, service frequency, and energy consumption.

Depending on your needs, you can select a BISON compressor in either a reciprocating piston design or a more common large industrial solution called a rotary screw design. Each has a different way of achieving the same result: creating compressed air.

Keep the air flowing with the fluids

BISON compressor offers one of the widest ISO viscosity grade ranges. Our wide selection of lubricants provides high performance in various environments, suitable for the most industries worldwide.

Air compressor motors are splash-lubricated, pressure-lubricated or oil-injected. Oil quality will be an essential factor in service frequency and parts replacement.

If you are mixing compressor fluids, not doing enough oil changes or running your compressor with less oil, you could face unnecessary repairs or complete system failure. Such situations will not only result in further equipment costs. They’ll also cause a loss in production and income.

BISON compressor offers fluids designed specifically for our rotary screw models and various operating environments. We offer reciprocating fluids for our pressure-lubricated and splash-lubricated models and aftermarket fluids. With the correct fluid for your compressor and working environment, you’ll extend the life of your components and save on labor costs.

Schedule maintenance for your work environment

Regular and proper maintenance should be addressed. Maintaining the integrity of your compressor will prevent disruptions to your business operations and keep your components in working order for as long as possible.

Parts for air compressors inevitably wear out, but regular maintenance can lessen how often you need to replace them. The frequency of necessary maintenance and outside service will vary depending on your compressed air demand and operating conditions. 

Understanding the components of your system at a basic level is necessary for air compressor functioning.

Parts of your air compressor

This alphabetical air compressor parts list contains parts for our rotary screw models and reciprocating piston models to help you become familiar with the functions of your air compressor:


An actuator produces rotary or linear motion and delivers compressed air to tools or processes that use compressed air for power. Any leakage or other reduction in air movement to the actuator will decrease air force output. Tiny particles that have found their way into the air will create blockages in the actuator and many other parts of your air compressor.


Air Compressor Bearings

Industrial-grade bearings ensure a long operating life for the most demanding operations. Quality bearings will give you satisfaction as your air compressor operates at high revolutions under high pressure. Bearings are highly dependent on proper lubrication at the correct adhesion location.


Belt tension needs to be checked every 40 hours for wear and operation. Belts must be of the highest quality and fit correctly as they work to drive your compressor.


Valve bumpers surround the valves for protection from accidental contact. Replace this small shielding section when needed to avoid more expensive valve replacement.


Bushings create space between moving parts and are used in the internal components of an air compressor. Your bushings protect against severe damage, minimizing play with each other.

Connecting rods

Heavy loads are carried by connecting rods as they raise and lower the piston in the crankcase. They are your air compressor’s most resilient component. If your system is not properly maintained, connecting rod replacement may never be necessary.


These parts are used on internal components to stop leakage from high-pressure systems.

Desiccant dryers/q-sorb

Our air dryers clean your compressed air by absorbing water vapor. A ‘wet’ compressed air stream passes through two pressurized tanks containing our highly absorbent desiccant. Q-sorb is an advanced formulation of activated alumina that significantly reduces operating costs. Keep your air dryer working efficiently with regular checks of desiccant and filters.

Gaskets and seals

To maintain reliable airflow and desired pressure, your air compressor must be airtight with quality seals and gaskets. Various parts of your air compressor have gaskets and seals: head gasket to valve plate, intercooler gasket, crankcase gasket, oil seal and shaft seal, to name a few. These small sections keep contaminants out and pressurized air in.


The gauge on an air compressor measures the air pressure in your tank. Your gauge is informative in several ways, especially for checking daily to ensure your pressure is at the desired level so you can correct any dips as soon as possible.


Your air compressor has an electric motor to drive the air-compressing operation. Different compressors require different-sized motors (HP). If you are replacing a worn motor, ensure the recommended replacement motor is installed.


O-rings help keep the system running at peak performance for a tight seal.

Piston rods and rings

Our reciprocating piston creates air pressure with the movement of the connecting rod and the piston. When they are in motion, these parts are under a lot of stress and require a lubricant of the highest quality and free from contaminants. Fluid analysis of your BISON fluid in a rotary screw compressor is critical to overall performance and early detection of potential problems. It’s also essential to use BISON oil to prevent premature wear on your piston rings, which prevents excessive oil carryover.


Our rotary screw air compressors’ assembly comprises two interlocking rotors that compress the air coming through the inlet valve. With proper operation, these rotors have a very long life.


Adding support spacers to your air compressor installation may be necessary. These metal shims will give you the support you need for a reliable system.


The various components of your compressor use springs for system mechanics. Determine when to replace the springs with a regular service check.

Unloader Valves

Allowing air out and in, draining water and regulating air flow, air compressor unloader valves are an essential component that requires regular inspection during your regular servicing and interval checks. Our quality-engineered valves are designed for flexibility and long life. They operate most efficiently using Buna-N or Viton seats and seals.

Pressure switch

Pressure switches activate or deactivate an electrical switch at a predetermined setting. Both fixed pressure settings and adjustable settings are available for these switches.

Pressure switches in compressed air systems respond to changes in pressure by allowing or denying an outgoing signal that is used to initiate operation. The action in our air compressor example is to turn the air compressor’s electric motor on or off.

Familiarize yourself with regular replacement parts

You will need to continue to check, maintain and replace these compressed air system components:

Air/oil separator

Before they become clogged and start losing performance, regular inspection of these elements and replacement filters should be a part of your maintenance programme.

Inlet air filter

air compressor air filters

The inlet air filter should be replaced on a regular schedule or if an inspection reveals that it needs to be replaced as an additional safety precaution to stop foreign particles from entering the air compressor system.

Oil filters

Maintain the essential quality of your lubricants with properly scheduled fluid changes and oil filter changes ready for your system’s activity and work environment. 

Understand the available air compressor accessories

You will also need additional air compressor components for your operations. Consider using these top air compressor accessories:

Filtration system

The compressor’s air filtration system uses filters to remove undesired particles, providing clean air for efficient results.

Air compressor filters remove the following impurities:

  • Humidity
  • Condensate
  • Gasses
  • Oil

Standard and high-pressure filters are available, also mist eliminators.

Air system piping

Air system piping often comes in different sizes to fit your air compressor. Over the years, these pipes may need to be replaced. Using air system piping that is designed for specific setup can make a significant difference in air compressor performance. The purpose of the pipes is to provide an uninterrupted supply of air from the compressor wherever you are using it, all while maintaining air quality, flow and pressure.

At BISON compressor, we offer custom piping, an air piping system constructed from an extruded aluminum alloy for reliable performance. Corrosion resistance and superior sealing technology help ensure performance and low cost of ownership for a leak-free system.

Hose reels

A hose reel is a helpful accessory that can make your job much easier. Hose reels keep air system hoses neatly contained. These accessories are beneficial if you use a replacement hose that is longer than the standard hose on your air compressor. Hose reels make air compressor operators’ jobs easier and contribute to a safe working environment.

Air compressor attachments

Adding air compressor attachments to your tools can significantly increase your capabilities. Having the right tool on hand saves time when a particular job is needed.

Some of the most commonly used compressed air system components and attachments include:

Nail guns: Industries like roofing and construction use nail gun attachments 

to drive nails faster.

Drills: An air compressor with a pneumatic drill adapter can quickly complete the task of drilling a hole in a piece of wood.

Sanders: Sand blocks are replaced by pneumatic sander attachments, which also lessen physical strain while working. These attachments are made for use with metal and wood applications.

Blowguns: Blowguns use compressed air to dry surfaces or remove dust and debris.

Paint sprayers: These attachments have various applicators to create smooth finishes quickly. The automobile, construction and machine manufacturing industries often use paint sprayer attachments.

Air pressure regulator

Air pressure requirements vary by application, so the air compressor needs to meet the demand. An air pressure regulator provides the right amount of pressure to your equipment to prevent air loss. This function enables you to maximize your performance.

Air pressure regulators can increase or decrease the air pressure on tools as needed. It can also extend the life of your hoses and pipes, as these fittings can wear more quickly if subjected to excessive pressure.

Reasons to purchase air compressor parts and accessories from the original equipment manufacturer

Purchasing air compressor parts and accessories from equipment 

manufacturers have several significant benefits for your organization that you can’t get with aftermarket parts. Some of these benefits include:


Genuine compressor parts are designed specifically for your air compressor. This means they are built to your compressor’s unique quality and performance standards.

When you replace old parts from an OEM with genuine components, you can expect them to perform exactly as well as what you’re replacing. This predictability eliminates the risk of misoperation or poor quality that comes with aftermarket parts. You’ll also protect your brand’s reputation by continuing to deliver the standard performance your colleagues and customers expect.


Because genuine equipment parts are designed with your compressor in mind, they provide better performance and more reliable operation than aftermarket solutions. As a result, OEM components reduce the risk of failure, resulting in higher production and uptime for your company. Due to their increased efficiency, original parts also reduce the frequency of pressure drops, leading to more significant energy savings.

With less energy and downtime from your air compressor system, you have more time and money for essential business tasks and potential operational improvements.


While OEM parts may cost more than aftermarket parts, they will save you more money in the long run. They are meant to serve as exact substitutes for your original ingredients and have a longer shelf life. You won’t have to spend as much money on replacement parts as often as you would on aftermarket parts. The opportunity to reduce breakdowns, save energy and increase operational efficiency offers more significant cost savings later.

Investing in OEM components will give you the best results when shopping for air compressor replacement parts.
