Manufactured in Canada, the Vortex Powerfan inline booster kit includes a 255 CFM VTX500 inline blower, for 5 in. Dia duct, and a current sensor that will automatically turn on and off the Vortex VTX500 inline blower as required. For example, In a clothing dryer application, when the dryer is turned on, the VTX500 will automatically turn on and will stay on for 5 minutes after the dryer is turned off. This will allow the dryer to perform better and more efficiently. Both, drying time and power consumption are therefore reduced.
