Primary Differences In Air Compressors

When it comes to air compressors, they each have their own unique uses that help benefit different types of businesses. It is crucial to know which air compressor is the right type for you. That way, you will have a compressor that works well towards your business needs and saves you money.

As said at Hertz Kompressoren, “You want an air compressor that works best for you and gives you a big return on investment.” Whether a reciprocating air compressor or a rotary screw air compressor, knowing their uses will make your choice easier. Each type of compressor has key differences that help determine which one is the best fit for you. Let’s go over them, shall we?

Reciprocating Air Compressor

A reciprocating air compressor is a positive-displacement compressor that uses a crankshaft-driven piston to deliver gases at high pressure. These types of compressors are known as the most energy-efficient of them all. At the same time, they’re known to have higher maintenance requirements than other types of compressors. For example, the piston ring needs to be replaced regularly to prevent gas leaks past the piston head.

There are great uses for a reciprocating air compressor. They’re used in industries where oil, natural gas, and chemical plants are present. At the same time, it’s used for refrigeration as well as in diverse settings like auto workshops and farms. Tools that run on this compressor type, such as drills, are lighter and safer than those with an electric motor.

Rotary Screw Air Compressor

A rotary screw air compressor is one that uses a rotary screw, air-end. Compressors like these are used where large volumes of high-pressure air are needed. The process for this type of compressor is much different from a reciprocating air compressor. Rotary screw air-ends produce compression in a continuous sweeping motion and there’s very little flow surge

These types of compressors use rotors to compress the air. These rotors precisely machined to even the most extreme tight tolerances. Air enters through the suction side of the air-end and goes through the rotor vanes when the screw rotors rotate. The air and oil are forced through the air-end via inter-twined rotors before they exit the screws’ end. The air and oil are cooled before the air goes to airlines and the oil goes back into the air-end.

Rotary screw air compressors are used for many purposes. The most common uses are for large industrial applications such as chillers. They’re also used to help operate high-power air tools like impact wrenches and jackhammers. A huge plus is that they have low leakage levels and low parasitic losses compared to reciprocating air compressors.

Air Compressors Bring You Unique Benefits For Your Unique Needs

It is clear that both the reciprocating air compressor and rotary screw air compressor would benefit you greatly. In the end, it all comes down to which one works best for the needs of your business. You also want to take into consideration what end result you’re looking for. Like they say at Hertz Kompressoren, “Look to compressors that bring you tailored results at a quality return on investment.”
