One, the pressure of the decision:

1. The higher the pressure, the greater the power consumption. Piping must be considered and pressure drop caused by pipe diameter size and length, and use pressure for the lower limit of pressure.

2. The use of various models listed pressure, such as using the pressure difference too much, you must purchase the air compressor of different pressure or use booster, can not be used to reduce stress and increase electric bills.

Second, the site:

1. Must be wide embellish of daylighting is good, operation and maintenance.

2. The temperature is low, less dust, the clean air and well ventilated place, below room temperature should be lower than 40 ° C.

Three, models of choice:

1. Calculate the total actual it is advisable to use air volume and margin (the company listed in the catalogue the actual displacement, are available in accordance with the ASME PTC - 9 test specification to test).

Note 2 the energy dissipation ratio, in order to save electricity. Both the actual displacement (m3 / min) divided by the elapsed horsepower (HP), the greater the value, the province electricity.

Four, compressed air quality and requirements:

The compressed air contains a lot of water, it for precision instruments, pneumatic tools, pneumatic equipment, valves, instrumentation, piping and cause great harm, because water will cause the corrosion, clogging instrument, the lower the quality of the finished product, equipment damage and loss of huge amounts of money Yu Xiuli maintenance work, so does have the necessary to add the clean compressed air compressor system.
