The key specifications for blowers include the intended application blower type port design as well as the parameters of flow capacity electrical ratings and dimensions.
Blower type exhaust fan.
Direct drive fans have fewer moving parts than belt drive fans for less maintenance.
A typical axial type ventilation fan will work okay for applications that don t require long hose or duct runs.
Outdoors consider a totally enclosed fan cooled tefc electric motor on direct drive units or a belt drive unit with an included weather cover.
Exterior wall mount exhaust fans good when you don t have room to mount an exhaust fan inside your facility these fans attach to an outside wall and work with or without duct.
Centrifugal type blower uses the centrifugal force generated by a rotating disk with blades mounted at right angles to the disk to impart movement to the air or gas and increase its pressure.
Blowers cool electronic enclosures induce drafts in boilers increase airflow on engines and are configured in a variety of blower system designs such as centrifugal.
The environment in which the system operates must also be considered to choose the right blower motor combination.
But if the exhausted air has to be moved a long distance through hose or duct work an exhaust blower will be needed to supply the proper exhaust air flow at the higher static pressures required.
Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink.
Dirty or dusty environment a tefc motor is best for longer life and optimal efficiency.
