DFBZ series low noise square type axial flow fan
One, characteristic and Application
DFBZ series fan with low noise fan motor direct drive; the whole Mechanism of square, beautiful appearance, convenient installation wall reservation square hole; the air outlet A self - vertical blinds, in order to prevent the outdoor rainwater and natural wind chamber with backward; There are obvious advantages of firm installation, small vibration, low noise, stable operation, Widely used in industrial and mining enterprises, civil building, gymnasium, animal husbandry, various Entertainment wall exhaust.
DFBZ-I is adopting the inner rotor motor direct drive structure form, DFBZ- II adopting the inner rotor motor, belt transmission structure form, type DBFZ-I for mining With external rotor motor direct drive structure. According to user requirements to obtain an Rot proof.
