Basic Model. Accesories NOT Incorporated.

Picture may differ from actual product

The Ventry® electric Fan (E-Fan), model 20EM3550, for positive pressure ventilation (PPV) and other commercial and industrial ventilation utilizes, is GFCI-safe, variable speed, will not exceed 15 Amps, even at start-up.. Constructed rugged and strong but not bulky, the fan weighs less than 80 pounds, fits in a small storage space, and moves an impressive 10, 500 CFM(17, 837 m3/hr).

The Ventry E-Fan combines efficient three phase technology with the all-terrain three-leg design and aircraft-style Securety Propellers exclusive to Ventry Fans. Being very quiet, low maintenance, and having zero emissions, it is also indispensable for overhaul and conditions in which 100% clean air is critical.

Model 20EM3550 is the modern equivalent to previous Ventry electric PPV Fan models 20E1.5 and 20E1.5GFCI.

Electric. An electric motor gives this fan several advantages, including: lower maintenance, no emissions, quieter operation, smoother operation, and ability to be tipped/oriented in any direction. (While most gas motors will shut down if tipped more than 20 degrees, electric fans may be aimed straight down into a man hole, straight up into an attic, or set at any angle in between.)

Three-phase technology. Compared to single phase systems, Three Phase offers reduced size and weight (25-50% less), delivers more power using less amperage, and allows programming of the motor to limit the power draw to 15 amps at start-up with no initial spike.

All-terrain legs. Three outward curving, independently adjustable legs made of solid, aircraft-grade aluminum, each having an simple-to-grab locking knob for fast, secure adjustments. They give the fan three-point stability, unlimited tilt/aiming, and fast deployment, Legs provide a rock-solid stance and truly stand-alone operation, no matter the terrain or obstacles (snow, stairs, standing water, debris, rose bushes).

Ventry safety propeller. Smoke-busting Securety Propellers move more air with less horsepower. This quiet, two-blade, aircraft style, status-of-the-art propeller provides great efficiency and durability. Most crucially, it is fail-safe. The propeller on 20EM3550 is specifically engineered to use all 1.5 HP efficiently.

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 when in utilize, even if it’s only 6 inches

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

Dual side handles And Top Arches. Side handles provide an simple, fast way for one or two people to lift and carry the fan. The frame also features tall arches on top which protects the controller from both sides and provides additional points for grabbing, carrying, and leveraging.

Long Distance Ventilation. Like all Ventry Fans, forward sweeping propeller tips produce narrow, consistent air stream for fan placement far from the target (8-15 ft is ideal). This leaves the entry and exit clear for firefighters and hose.

Warranties. Backed by 1.5-year warranties on the drive and controller, our overall 5-year “no BS” warranty on workmanship and materials, and lifetime factory helpance.
