6-5 Check valve
A check valve plays an important role in the scroll air compressor.
The valve prevents the backflow of the compressed air when the
compressor is stopped to protect the compressor from damaging
due to a back-lashing. The valve also protects the wrap of the
compressor from damaging due to foreign substances back flown
from the pipe to the compressor. The valve is designed to stand
against a repetitive pulse motion of scroll at a high temperature
392℉ or above.
The cooler assembly consists of an air cooler, a cooling fan, a fan motor and a fan shroud (duct).
A cooler element is an aluminum cooler that is designed to be used up to 217.5 psi. Dust may
increase the temperature in the cooler pin, which needs to be cleaned with the compressed air or
a detergent on a regular basis. When cleaning, cover the electric parts to keep the water out.
An airend consists of precision parts that need a clean air to be used for
an optimal service life. Coaire air compressor is equipped with
a paper suction filter that has 99.9% of the dedusting efficiency.
The filer needs to be replaced every 2000-3000 hrs. If it is unavoidable
circumstance, the reuse is only allowed once after cleaning.
※ Make sure to use only the genuine Coaire suction filter.
