The Tempest Special Operations Power Blower™, or SP for short, is the latest addition to our extensive line of world famous Power BlowerTM. This same air pattern is also designed to be deployed 9 – 11 feet from the entry point, providing additional access for personnel.

Honda® GX200 and GX270 Engines

The SP positive pressure ventilation fans are powered by the tried and true Honda® name. Using two of their most reliable small engines, the GX200 and GX270, paired with Tempest’s signature quality fan designs, these units are built to last. At 5.5 and 8.5 HP, the GX series motors are also equipped to deliver the performance and CFM you’d expect from the Tempest name.

Welded Steel Roll Cage Frame

The roll cage frame acts like a 360° roll bar, protecting the engine, shroud and the operator. If the positive pressure ventilation fan falls backwards, the frame and back wheels touch the ground, instead of the engine. If it falls forward, the lifting handles and front legs touch the ground, not the shroud. The roll cage design also provides added protection for the operator by making it easier to lift and carry.

Laminar Air Flow

The Special Operations (SP) Power Blower™ uses a uniquely designed grille and shroud to produce a narrow, high pressure air pattern called Laminar Air Flow (LAF). Fires in large, complex structures as well as multi-level structures build high back pressures inside the building. LAF’s high pressure air pattern is capable of overcoming these back pressures resulting in uninhibited ventilation.

Extended Set Back

Cone Air Flow fan placement has always been 4 to 6 feet from the doorway. The SP fan is most effective at a set-back of 9 to 11 feet using Laminar Air Flow, allowing improved personnel access. The new shroud and grille design makes high performance at this distance possible. SP units require at least a 7 foot set back to achieve effective positive pressure ventilation.

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 blower’s listed dimensions.

Six Position 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 6 tilt positions: -10°, -5°, 0°, +5°, +10°, +15°.

Rear Wheel Design

The rear wheel design improves the PPV fan balance while it is rolling, keeping the shroud from touching the ground and making deployment easy across snow, heavy mud or rough, uneven terrain. This design also allows for rapid blower direction adjustment saving time and improving safety. Tempest blowers have no need for wheel brakes. This in turn removes the chance for forgetting to set/release the brakes.

Information/Safety Bar

The Information/Safety Bar added to the folding handle features a large section of durable, reflective material to dramatically increase visibility of the PPV fan from front view and a full list of instructions to allow for safe and effective use.
