GFCI/NEMA 4 Variable speed Drive

The VSR positive pressure ventilation fan bears our latest 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 the unit quickly and effectively.

Performance 2.0 HP Motor

You don’t always have to sacrifice performance for the convenience of an electric powered positive pressure ventilation fan. Our latest Power BlowerTM, the VSR, is closing the CFM gap between gas and electric. Equipped with a massive 2.0 HP motor, paired with our signature blade and shroud design, the VSR delivers the absolute best in GFCI compatible performance. If you’re looking to go electric but don’t want to sacrifice airflow, the VSR PPV fan is the answer.

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 blower rests on firm, anti-vibration rubber feet for stability. “Walking” or movement of positive pressure ventilation fan while in operation is eliminated. Risk of getting clothing in blower blades while kneeling to set brake levers is eliminated. 16″ blowers are available only 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 BlowerTM. 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 a 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 PPV fan’s listed dimensions.

Dual “Winning Step”

No levers to set or knobs to tighten when setting the angle for PPV. Foot operated adjustment is quick, easy and secure. Dual step allows for adjustment with either foot. Four back and one forward tilt position.

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.
