Air / Oil Separator 
An air/oil separator removes oil from the air that comes into contact with the rotary screw compressor. This allows the oil to be recirculated. an air/oil separator is an element of the system that is often overlooked. It is however a critical piece of equipment in any air compressor, as its function is to remove oil contaminants from the compressed air before it enters the discharge piping. The oil/air separator is a simple device that uses centrifugal force to remove the oil from the air stream. As the compressed air enters the separator, it is directed onto a series of baffles that deflect the airflow. This causes the heavier oil particles to be thrown to the outside of the separator where they are collected in a drain pan. The clean air is then allowed to pass through to the discharge piping.

Air Receiver 
The air receiver is the tank where compressed air is stored. The size of the tank depends on how the compressor will be used. The manufacturer will recommend a good size for the tank.

Check Valves
 A check valve only permits flow in one direction and blocks the flow in the opposite direction.

Coalescing Filters
A coalescing filter is a filter that helps remove dust, particles, and oil from the air. The coalescing filter is a vital component in ensuring that the compressed air is clean and free of any contaminants that could potentially damage sensitive equipment or products. Coalescing filters are typically installed in the air compressor's intake system, and they are often used in conjunction with other types of filters, such as particulate filters, to provide the highest level of protection for the air compressor and the equipment it is powering.

Couplings
A coupling connects the two halves of the crankshaft. The coupling is located between the motor and the pump. There are two types of couplings: rigid and flexible. Rigid couplings cannot accommodate any misalignment between the shafts, while flexible couplings can accommodate a small amount of misalignment. Most air compressors have rigid couplings.

Control Valves
A control valve helps to regulate the air pressure within the system. By modulating the air pressure, the control valve ensures that the system operates at peak efficiency and can maintain a consistent output of compressed air. Without a properly functioning control valve, an air compressor system would be less effective and could potentially cause damage to equipment or injure operators.

Controllers
A controller monitors and adjusts air pressure, ensuring that the air compressor does not overheat and that the air pressure is maintained at a consistent level. There are various types of controllers, but their overall goal is to keep the air compressor functioning properly. Many controllers are motherboards, which contain a variety of sensors and switches that allow the air compressor to function properly.

Desiccant
A desiccant is a substance that helps keep things dry. Its purpose is to adsorb water molecules from the air and keep them from condensing on surfaces or forming droplets. Desiccants are commonly used in air compressors to help prevent moisture build-up and corrosion.

Discharge Valves
It releases compressed air from the tank when the pressure in the tank has reached its maximum. The discharge valve is also responsible for re-admitting air into the tank when the pressure in the tank has dropped below a certain level.

Drains Valves
A drain valve is a device used to remove liquid from a compressor. This can be done manually, with a float, or electronically.

Dryer Filters
Dryer filters dry the air before it enters the air compressor. This is a very important function because if there is moisture in the air, it can cause problems with the air compressor. The moisture can cause the air compressor to rust and it can also cause the air compressor to freeze up.

Compressors Fan
A fan takes air and directs it into the compression chamber. The fan is also responsible for moving cooling air through the compressor to keep it from overheating. As air is compressed, it becomes hot. The cooling air that the fan blows over the compressor helps to dissipate this heat and keep the compressor operating at a safe temperature. If the compressor gets too hot, it can be damaged or even catch fire.

Filter Housing
The filter housing is a protective casing that surrounds an air filter, oil filter, separator, or coalescing filter. The strongest filter housings are typically metal, but they can also be made of plastic.

Gaskets
A gasket makes a seal between two metal surfaces so that air can be compressed inside the unit. Gaskets are made of a variety of materials, such as rubber, cork, neoprene, and silicone. In order for a gasket to work properly, it must be soft enough to make a seal, yet firm enough to stay in place. If a gasket is not the right size or material, it can cause problems.

Gauges
Within an air compressor, there are different types of gauges, such as the pressure gauge, the temperature gauge, and the oil level gauge. The purpose of these gauges is to help the operator of the air compressor keep track of how well the machine is functioning. By monitoring these gauges, the operator can make sure that the air compressor is working properly and not overworking itself.

Heat Exchanges
A heat exchanger cools the compressed air after it has been used. This is done by exchanging heat between the compressed air and another medium, usually water or air. Air-cooled heat exchangers are typically used in situations where water is scarce or expensive, or where the air is already at a temperature that can be used for cooling.

Inlet Air Filters
An inlet air filter removes dirt and contaminants from the air inside of an air compressor. Air filters are essential to ensuring the life of the compressor.

Inlet Valves
Inlet valves admit air into the compression chamber. The valve is located at the inlet end of the cylinder, where the piston is moving towards it during the intake stroke. Air enters through the inlet valve and is compressed by the piston as it moves toward the other end of the cylinder during the compression stroke.

Intake Valves
Pretty simply, the purpose of an intake valve is to let air in. The intake valve is opened when the piston is at the top of its stroke, and it allows air to flow into the pump chamber. The intake valve is closed when the piston is at the bottom of its stroke, and it allows the air to be compressed. The intake valve is opened and closed by a cam, which is actuated by the compressor's crankshaft.

Muffler / Silencer 
Air compressors are noisy machines, and the intake silencer, or muffler, helps to muffle that noise. Mufflers work by redirecting the airflow from the intake port so that it hits the back of the compressor head instead of passing through the head and out the exhaust port. The redirected airflow causes a ''back pressure'' that helps to quiet the machine. Mufflers also help to keep dirt and other debris from entering the compressor head, which can damage the piston and other internals.

O - Ring
An O-ring is a circular seal that is placed around a rotating shaft. The O-ring is designed to keep air from leaking out of the compressor. There are two types of o-rings: static and dynamic. Static o-rings are used to seal stationary parts, such as the air inlet and outlet ports. Dynamic o-rings are used to seal moving parts, such as the piston or crankshaft. If an O-ring is not properly sealed, it can cause the compressor to work less efficiently and may even damage the compressor over time.

Oil Filters
Oil filters help to remove impurities from the air compressor oil, keeping it clean and extending the life of the compressor. The types of air compressors that use oil filters include reciprocating air compressors, rotary screw air compressors, and scroll air compressors.

Oil / Water Separator
An oil/water separator is used to remove oil and water from compressed air. The oil/water separator is an important part of a compressed air system as it helps to extend the life of your air compressor and other equipment by preventing oil and water contamination. There are a few different types of oil/water separators on the market, but they all work by using a baffle system to separate the oil and water from the compressed air. The most common type of oil/water separator is the coalescing type, which uses a series of baffles to coalesce the oil droplets in the air and then separate them from the water. Another type of oil/water separator is the cyclonic type, which uses a spinning motion to separate the oil and water.
