M-4DBT Automatic Dryer Vent Booster Exhaust Fan 4" Duct, 200 CFM High Airflow, 130 Min Delay Adjustment, Improves Long-Vent Ventilation & Reduces Lint Buildup

Enhanced Drying Performance: Engineered for long or bent dryer vents, this Dryer Vent Pressure Booster substantially increases exhaust efficiency and helps reduce drying time. Eliminate waiting through multiple cycles for a single load, and avoid concerns about residual moisture causing unpleasant odors or energy waste.
Automatic Pressure-Responsive Function: The built-in pressure sensor enables the fan to start and stop automatically with your dryer. When pressure drops, the fan turns off independentlyno buttons, no manual effort. A smarter, hands-free method to maintain smooth drying cycles.
Optimized Long-Duct Ventilation: Designed for vent systems exceeding 25 feet or with several bends and compatible with all dryer brands, this dryer vent pressure booster provides a powerful 200 CFM airflow while operating quietly. Simply install it on a straight section away from the dryer outlet to greatly enhance exhaust flow and realize genuine energy savings.
Robust Construction & Intelligent Control: Constructed with a durable metal exhaust fan and a premium controller, this unit offers enduring dependability. The digital display clearly indicates system status, and the adjustable 130 minute delay run assists in clearing residual lint, maintaining your vent system's efficient operation.
Safe & Energy-Efficient Function: Inadequate ventilation not only prolongs drying but can also generate concealed fire risks from accumulated lint. This automatic exhaust booster utilizes an integrated pressure sensor to activate the fan as required, minimizing lint accumulation and decreasing potential fire dangers. It is the perfect upgrade for safer, more effective drying performance
