DJF type exhaust fan

中国负压风机生产标准的起草者!

A、The outline border has adopted advanced automatically
Manufactured techniques with extremely high accuracy.
Specially thick galvanized layer with extremely strong anti-corrosive ability;
B、 Special high intensity alloying wheel, Newly twisted punch press blades, reasonable blade angle and achieve the biggest air volume. High precision microcomputer aided manufactured system can make fans maximize efficiency;
C、Five strict quality testing procedures: noise, vibration, rotary concentric performance wind blades speeding, assembly efficiency measurement. High-powered 380v special motor, CAD optimized design.

D、The use of stainless steel fanleaf, without distortion, no breaking, aesthetic durability, radically improve aluminum fanleaf fracture problem.
E、Adopted automatic belt adjuster which can adjust up and tight so that it can’t pine belt and drop belt
F、the strap wheel adopts more stiffening rib and processed by sandblasting, become attractive, eliminate the internal stress and increase own emphasis efficiently
G、variety sizes of shape and install conveniently,Size of shape:780mm*780mm*420mm、830mm*830mm*400mm、900mm*900mm*400mm、1100mm*1100mm*400mm、1220mm*1220mm*400mm、1380mm*1380mm*400mm、1530mm*1530mm*400mm seven kinds.
