VTX400C weight & dimensions

Vortex Powerfans VTX400P & VTX400C inline blowers, for 4 in diameter duct, are ideal to solve the problems caused by long duct runs on clothes dryers. In a clothing dryer application, when the dryer is turned on, the VTX400P and VTX400C will automatically turn on.


The VTX400P has a built in automatic pressure switch that detects when air is flowing through the ventilation duct. It will automatically turn on for a period of 10 minutes and shut off for a period of 15 seconds and turn back on if there is still positive pressure from the dryer.


The VTX400C is supplied with a current sensor that detects when the dryer is turned on to automatically activate the fan. The current sensor is available either with or without a five minute turn off time delay.

Dryer duct boosting is typically required when duct length exceeds:

When is a dryer duct booster required?

Every bend is equal to 5 linear feet.

When installing a clothing dryer duct exhaust system, please ensure to follow all applicable building codes and manufacture’s recommendations.

Ideal clothing dryer venting arrangements with short duct length are often not possible. Both commercial and residential clothing dryers should normally dry the clothing in a timely matter. Due to venting restrictions, clothing dryers with longer duct lengths will typically take a longer time to dry and consequently consume more power. An inline vent boosting blower is a smart solution to this problem.
