DZ series low noise blower fan Application
DZ series low noise axial flow fan is a new type of axial flow fan. This series of products are widely used in wall exhaust, post air supply and duct ventilation in industrial and mining enterprises and civil buildings.
Structure type
It has the characteristics of high efficiency, low noise, stable operation and convenient installation.
The blades can be made of aluminum alloy, ABS engineering plastics, FRP glass steel and other materials as required.
Maintenance and use of fans
Operation is permitted only when the fan is in perfectly normal condition.
It is required to check each part of the fan for normality in case of startup of the fan upon maintenance.
The fan shall be cleaned regularly and the dust, dirt and other impurities inside conveying pipeline shall be removed at regular interval to prevent rust.
It is not allowable to repair the fan when it is in operation.
A throttling device may be used for adjustment in case of excessive flow which not in compliance with operating requirements or smaller flow required in a short time.
The fan shall be immediately stopped for inspection in case of abnormality during its startup, shutdown or operation.
