2020 Tempest Belt – Drive BD-21-H-5.5

Tempest’s Belt-Drive Power Blowers are what started it all and stand today as the premium gas powered positive pressure ventilation fan.

Tempest’s Belt-Drive Power BlowersTM are what started it all. The first versions of this positive pressure ventilation fan were designed in the late 80’s to introduce Positive Pressure Attack (PPA) to the fire industry. Today, our current models boast a number of updated features and changes from the old version, but still hold true to the original idea: Keep the motor low to the ground to reduce vibration and perfect the pulley system to maximize RPM/performance. The BD’s are the only PPV fans available in a 27" model. Originally designed for FDNY, the 27" Belt-Drive is the ultimate positive pressure ventilation fan (PPV fan).

Features may include:

• The Tempest Belt-Drive positive pressure ventilation fans were designed with two major goals in mind. The first was to keep the engine at the lowest center of gravity as possible. Doing so greatly reduces the amount of vibration produced by the fan and guarantees it will not “walk”. Secondly, the belt/pulley system allows Tempest engineers to maximize the RPM’s at the blade, optimizing CFM output. The Belt-Drive has been categorized as the “Cadillac” of PPV fans.

• Gasoline powered fans offer the highest CFM performance available. Ranging anywhere from 4.8 to 8.5 HP, these positive pressure ventilation fans are recommended for the implementation of Positive Pressure Attack (PPA) in residential structures.

• 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.

• 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 positive pressure ventilation fan rests on firm, anti-vibration rubber feet for stability. “Walking” or movement of blower while in operation is eliminated. Risk of getting clothing in PPV fan blades while kneeling to set brake levers is eliminated.

• 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.

• 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.

• 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 tilt positions: -5°, 0°, +5°, +10°, +15°.

• 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.
