Fan:
High efficiency low noise electric motor with imported top tier maintenance free bearings is adopted, together with new developed centrifugal blower with adjustable air flow rate by 3-stage. The designed fan service life is up to 100,000 hours. The power input is 380v/50Hz.

Heat Exchanger:
CPDR-A series adopts infra-red aluminum alloy plate fin innovated by ourselves, which was patented. Draw-through fan position is designed, and the air passing through the heat exchanger is even and steady, no air flow dead zone within the air curtain enclose.

Filtration Device：
Coarse filter will be included on the air inlet side to avoid dust accumulation within the heat exchanger to block the air flow. The filter is made by either synthetic polyester fiber (PET) or aluminum alloy mesh net.
