Filter Fans
Filter Fans are suitable for use in electrical cabinets
and enclosures in which excessive heat develops
due to the high density of equipment. Overheating
can cause damage to the components inside.
Proper selection of lter fan and vent will create a
low positive pressure and ensure clean ltered air
circulates through the enclosure.
GHV Series Fans with properly selected vents
circulate air through the enclosure by drawing in
cooler air from the outside and forcing warm air out.
The GHV series are available in various sizes.
How Filter Fans and Vents Work
Installation Instructions
Install the fan in the bottom of the cabinet so that
the incoming air can rise and thus dissipate the heat
produced by the electrical components. Install the
vent in the top of the cabinet.

Filter Fan Selection
Air ow required to dissipate heat from the
enclosures should be calculated.
Example:
Heat to dissipate: 1,200 Watts
Desired temperature drop from
ambient:
20° C/K
