FFU-280 backward curved impeller fan is composed of an overload thermal protection outer rotor motor and a high efficiency backward tilting circular arc centrifugal impeller. It has the characteristics of high efficiency, low noise, low vibration, low temperature rise, stable pressure curve and wide application range. It is mainly used for FFU clean workbench and FFU laminar flow hood.
Impeller Material: Galvanised Sheet Steel
The difference between forward-inclined centrifugal fan and backward-inclined centrifugal fan
1. Power: The static head used to overcome the resistance of the system. The forward tilting centrifugal fan is smaller than the backward tilting centrifugal fan.
Since the channel in the backward tilting blade fan is gradually enlarged, the loss of the force is smaller than that of the forward tilting type.
Therefore, the efficiency of the forward-inclined centrifugal fan is lower than that of the backward-inclined centrifugal fan.
2. Power consumption: Since the efficiency of the forward-inclined centrifugal fan is lower than that of the backward-inclined centrifugal fan, its power consumption is greater than that of the backward-inclined centrifugal fan.
3. Noise: The running noise of the forward-inclined centrifugal fan is greater than that of the backward-inclined centrifugal fan.
Mainly used for purification workbench, purification unit, ventilation pipe dust removal, purification air conditioning system, environmental protection and pollution control and other refrigeration equipment supporting work. It is widely used in ventilation of hotels, restaurants, schools, factories and other places and civil and industrial buildings. It is suitable for environmental and air conditioning systems with strict noise requirements, such as cooling with industrial refrigeration systems, kitchen fans, fire fans and communication equipment. Equipment, small condensing unit, air purifier, air filter, roof fan, duct fan, air cooler unit, modular unit, air conditioning ceiling machine and other equipment.
