The VSG positive pressure ventilation fan was one of the original variable speed, GFCI compatible Power Blowers™ to hit the fire service. Today, it’s now one of the most popular. Powered by its 1.5 HP motor, the VSG PPV fan is guaranteed to provide high performance, reliable ventilation while running on nearly any rig or house hold wall outlet. The variable speed control makes the VSG perfect for ventilating a wide range of both small and large structures.

GFCI/NEMA 4 VariAble speed Drive

The VSG positive pressure ventilation fan is equipped with a time tested and proven variable speed drive. This GFCI compatible, NEMA 4 rated control box is durable, reliable and easy to operate. The 0 – 100 Rheostat knob and On/Off toggle are all it takes to operate this PPV fan quickly and effectively.

Welded Steel Roll Cage Frame

Every bend and cross brace weld is structurally engineered to increase the blower frame’s strength to weight ratio by as much as 30%. Welds eliminate the need to continuously maintain/tighten nuts and bolts. Its roll cage design gives protection to all angles and sides of the shroud and motor.

8” Non-Pneumatic Wheels

Extra wide 8” off-road non-pneumatic tires are more durable and allow easy movement up and down stairs, over curbs and large diameter hoses, as well as through rough or muddy terrain. No brakes to forget to lock down or unlock. The PPV fan rests on firm, anti-vibration rubber feet for stability. “Walking” or movement of the fan while in operation is eliminated. Risk of getting clothing in the positive pressure fan’s blades while kneeling to set brake levers is eliminated. 16” models are only available with 6” non-pneumatic tires.

Turbo 2000 Shroud

By redesigning the inward curve and front of the shroud, the Turbo 2000 increases air velocity by up to 30%. The air hitting the ventilation opening is stronger and maintains PPV pressure farther downwind.

AirFlex Composition Impeller

Uniquely designed impellers deliver maximum air volume (CFM), velocity and pressure from each Tempest Power Blower™. Every size and type of fan features a blade designed specifically for it to deliver the greatest performance possible. Composite blades are much safer than traditional metal blades as they are designed to disintegrate upon impact of any foreign objects. Metal blades may fragment when integrity is compromised, potentially causing severe injury.

Flip-Up/Fold-Down Handle

The exclusive full width handle design makes pushing or pulling the positive pressure ventilation fan to and from the ventilation site quick and easy. The handle quickly swings up to a comfortable height and automatically locks firmly into position. Unlatch and easily fold the handle down for storage at the fan’s listed dimensions.

Dual “Winning Step”

No levers to set or knobs to tighten when setting the angle for PPV/PPA. Foot operated adjustment is quick, easy and secure. Allows for up to 5 (4 on 16” models) tilt positions: -5°, 0°, +5°, +10°, +15°.

Safety Grille

Front and rear safety grilles feature a continuous spun wire body with eight tie point bars that also support the “Turbo 2000” shroud integrity. Meets strict European CE Safety Standards.

Information/Safety Bar

Features a large section of durable, reflective material to dramatically increase visibility of the blower from front view and a full list of instructions on the back to allow for safe and effective use.
