The Basics you need to know on Air Compressor Purchase

Energy can neither be created nor destroyed; rather it can convert into other forms. That is why; you need the most appropriate air compressor machine for effective utilization of the available energy resources. This report precisely covers the available types of air compressors and considerations on purchase for perfect work satisfaction.

Air compressors utilize the air freely available in the atmosphere, to convert it into potential air energy. It works under compression principle, where air sucks in and squeezes into fine compact particles with a significant pressure value. For satisfactory application, the air compressor should fulfill the above task with the most efficacy possible.

The type of compressor used depends on the working pressure and the volume of air. This brings about three main categories of compressors.

1. Reciprocating compressors

Are available in two types, single and two-stage compressors. The single-stage discharges the compressed air directly into the system or a receiver. The two-stage on the other hand compresses air in two stages, first to a medium pressure level, cooled then compressed further to the desired end pressure.

A two-stage compressor can stand more air pressure hence ideal for demanding applications. If your intended work lies in this category, then a two-stage will be ideal for appropriate air compressor price in Kenya selection. The available reciprocating types include piston compressors and sliding vanes.

2. Rotary Screw Compressors

These are new approaches that run parallel in working principle to the traditional reciprocating ones. Two meshing rotors {concave and convex} employed to draw in air and trap it into a compression receiver. They come in two types, oil-injected, and oil-free compressors.

They best suit applications that require a large continuous supply of compressed air and can substitute the reciprocating models.

3. Turbo Compressor

Works under the dynamic principle i.e. use several impellers of different sizes to supply compressed air. The pressure rises in stages of the approximately same amount to greater output. The available types are; mixed flow, centrifugal and axial compressors.

Purchase considerations

Getting to know the most suitable type of air compressor you need is just the first step into purchasing the ideal one. Thus, what follows next is the design and performance ratings. Be keen not to ignore any of the listed below while evaluating air compressor prices in Kenya:

Pressure rating – usually in PSI (Pounds per Square Inch). It shows the maximum pressure that the compressor can deliver in its outlet nozzle. Most average power runs at 90 PSI while large power covers up to 175 PSI.

Tank Size – The tank acts as the accumulator unit. The larger the tank, the more time is required for pressure build-up. Hence, small tank capacity is preferred for intermittent demands while large tank size is suitable for large air pressure demands for an extended time.

Horsepower Rating – this defines the torque affected by the generated air pressure. Hence, it is the foremost choice to suit a given application. However, the ratings differ with the type of energy used to run the machine. Electric compressors would perform the same task to a gas engine type with a higher rating.

Duty cycle – defines the working time of a given compressor for a stated time. If this value exceeds, it will lead to overheating of the compressor unit. The duty cycle is usually as a percentage of the set time. Most industrial centers use those with 75-100% range.


According to Air compressor Nairobi, the most reliable work efficiency calls for outstanding equipment selection. Therefore, an ideal air compressor, which is work satisfactory, requires adequate information for selection. All you need is the relevant ideas that are precisely clear in this report.
