The portable ejector fan is a rugged and simple device designed
to control ventilation by either exhausting air out or forcing
fresh air in. The blade design provides for sure operation under
severe conditions. Motors are available in either totally enclosed
or explosion proof. The units conform to OSHA regulations and
are easily portable. Areas of application range from farm and
industry to fire and emergency police.
Flexible duct hose is available for both the 16" and 20" portable
ejector fans. These durable hoses are available in 20 foot lengths
and provide the ability to intake or exhaust air through an opening
some distance away. The hose is quickly connected to a mounting
flange by a single clamp. The mounting flange and hardware are
included with the hose. The hose is disconnected and easily collapsed
for convenient storage. It should be noted that when a duct hose
is added to a fan, it will increase resistance and reduce the
cubic feet per minute of air the fan will move.
