What Air Compressor Do I Need?
With so many different types of air compressor available, it is often difficult to make a decision on what one you actually need. We are here to help you make an informed decision on what is the best for your business, workshop or home garage and any other application.
Ultimately the air compressor you need is unique to you and your businesses application. Meaning that all of the following is taken into account before making a decision: maximum air demand, length of time air is required for, frequency of use, environment the air compressor will be situated in and electricity supply available.
Piston Compressors – Also known as reciprocating compressors, is classed as a positive displacement compressor. This means that it uses pistons that are driven by a crankshaft in order to deliver air at a high pressure. The function involves the intake air entering the suction manifold, then flowing into the compression cylinder, where the reciprocation motion of the pistons within the cylinder draw in and compress air.
They are versatile and durable, whilst the robust construction can allow for arduous operation in very demanding environments when correctly sized and operated.Piston compressors are capable of being energy efficient, a key advantage is the use of a constant speed control valve. Unlike rotary compressors a piston compressor can work for only one hour a day, if that is all that is required. Reducing energy wastage by not having to reach an optimum working temperature.
Screw Compressors – Rotary screw compressors use a rotary type positive mechanism. There are a set of male and female rotors, that are designed differently so that, when turned in unison, air will become trapped between them. They mesh together without touching to achieve compression. The air volume is reduced as it moves through the rotors, resulting in compressed air.
Fixed speed rotary screw compressors are commonly used in applications where continuous volumes of high pressure air is required for a consistent period of time. Variable speed rotary screw compressors are commonly used in applications requiring a fluctuating demand in compressed air. The inverter technology allows the compressor to smoothly adjust the motor speed and power consumption to respond to any changes in air demand. However, this comes with the added complication of more electrical components.
