How To Choose A Screw Compressor

Pressure Determination

• The higher the pressure, the more electricity costs. The size and length of the pipe may cause some pressure drop, therefore the total pressure drop plus the required operating pressure is the minimum required compressor output pressure.
• Choose the pressure according to the actual requirement, or it will increase the unnecessary electricity cost.

Air Demand and Model Selection

• Calculate the total air demand and add reasonable capacity for contingent or unusual usage and future expansion.
• Check the ratio of air delivery (m³ /min) over the power consumption (Kw). The bigger the ratio, the more efficient it is.

Quality of the Compressed Air

• Water in the compressed air will damage important components in the circulation system such as sensors, pneumatic tool, pneumatic devices, valve, pipes, etc. Because water will rust or obstruct the air passage, hence reduce the product quality and increase the cost for maintenance. It is necessary to install the “compressed air filtration system “
