Five Factors to Consider Before Buying an Air Compressor

 

Air compressors can work wonders in garages and workshops. This is taken into account when electrical and construction projects have to be carried out. Therefore, it is very important to choose a suitable product to improve work efficiency. When determining the right factors, several factors can be considered, including the following:

Source of power

Electric ones are easy to carry around, but finding a plug can be a problem. When some activities take place indoors, people have no choice but to choose electric. This is because the gas gives off smoke. However, gas-fired ones are more effective than electric ones. The required voltage is determined by the power required by the compressor. A 2HP motor needs a 220-240V outlet, while a regular household compressor only needs 110-120V.

Piston or portable

The piston engine has a rotating motor that participates in increasing the air pressure during the exhaust process. Therefore, an increase in air pressure corresponds to an increase in air consumption. The air compression in the piston requires a high level of maintenance. It is best suited for commercial and industrial applications rather than trivial tasks.

The portable device can perform the functions of a piston device without the use of a fuel tank. The portable compressor can provide a constant level of air pressure for a long time, making it suitable for domestic applications such as plumbing, pumps and other household appliances.

The piston type is more expensive than the portable type, mainly because the piston type has a fuel tank and a portable device.

Single stage or two stage piston

The air compressor is equipped with two types of pistons: a single-stage pump and a two-stage pump. The single-stage air compressor draws in air through the action of a single-stage piston and compresses it to the required pressure. 150 PSI is the maximum pressure a single stage piston can produce. Single-stage reciprocating air compressors require higher CFM values ​​than two-stage air compressors.

The two-stage compressor has two pistons, which can complete the work of a single piston in a single-stage air compressor. However, the work of the two stages is slightly different because the process does not end with compression. Instead, the piston compresses the air, allows it to cool, and then compresses it again. The two-stage type is more effective because the air is cooled as it is compressed, increasing its density. The two stages use their air pressure without losing it at any point. These can reach a maximum pressure of 200 PSI.

noise

If noise is an issue, choose oil lubrication over oil-free lubrication. Oil-free machines do not require oil to lubricate the flat areas of the machine. Oil-lubricated air compressors are more effective than oil-free air compressors.

Thermal protection

Provide thermal protection in the air compressor as a switch to shut down the motor when it overheats. Considering the investment made, the customer should choose a product that offers a thermal protection switch.
