Ventry PPV Fan Model 20GX120

  • 0.00

Gasoline powered Ventry® Fan with a 20-inch propeller and a 3.5 hp Honda GX120.

This Ventry Fan model is very popular and a great choice for those who want minimal weight and do not need an optional Entry Point Light. With the smallest motor, it is one of the most convenient and easiest to operate. This blower is most often used by fire fighters for positive pressure ventilation; it is small and easy to use but performs as well as or better than many others of equal or even greater size and horsepower.

ALL-TERRAIN VERSATILITY. The three legs on this fan give it three-point stability, unlimited tilt/aiming and fast deployment. No matter the terrain or obstacles, the outward curving legs provide a rock-solid footprint and truly stand-alone operation. Legs provide the versatility to perform well in any terrain, any season, any scene.

VENTRY SAFETY PROPELLER. Two-blade, aircraft style, state-of-the-art propeller, engineered specifically for the 3.5 hp motor. Provides high CFM, longevity, and fail-safe performance.

CLEARANCE. Up to 14 inches between propeller and ground allows no intake of foreign matter so debris won’t be picked up or plug the fan. For added safety and performance, always extend the legs on your Ventry Fan a minimum of 6 inches when in use.

FREE-FLOW GUARD. Un-shrouded, double reinforced wire guard allows maximum air supply to the propeller which increases air volume (CFM) and decreases noise. Video: noise drops and CFM increases as a solid shroud is removed from a Ventry Fan in this demonstration.

DUAL SIDE HANDLES. Side handles provide an easy, fast way for one or two people to lift and carry the fan.

LONG DISTANCE VENTILATION. Forward sweeping propeller tips produce narrow, consistent air stream for placement far from the target (8-15 ft is ideal). Fan is well out of the way of crew and equipment and allows safer and more effective ventilation.

GX HONDA ENGINE. The Honda GX120 is a 3.5 hp heavy-duty motor featuring cast iron bores, low-oil shut off protection, an on/off switch separate from the throttle, and a fuel shut-off valve.

WARRANTIES. Backed by a 3-year warranty on the Honda motor, our overall 5-year “No BS” warranty on workmanship and materials, and Lifetime Factory Support.
