Dryer Booster Fan System – Increase Dryer Performance for Long Extended Dryer Vent Exhaust RunsThe VENTS-US VK 100 PS Dryer Booster Fan System is specifically designed for dryer ducting that exceeds 15 ft. in length or includes multiple bends, where airflow resistance can compromise dryer efficiency. Installing a booster fan in these scenarios ensures proper ventilation of heat and gas, helping maintain dryer performance and safety.This model includes a built-in pressure-sensing switch that automatically detects airflow and activates the fan during drying cycles-then powers off when the cycle ends. The pressure sensor is easy to adjust for your specific dryer by turning a screw within the switch (see the troubleshooting guide for detailed instructions).This dryer booster fan can be hardwired and mounted on the wall or ceiling. Enhance your dryer’s efficiency, reduce dryer error codes, and reduce heat and lint build-up for any residential, commercial, or industrial dryer.
