Since 1987, Tempest Technology Corporation has been a leader in the development of innovative ventilation tools for fire fighting and industrial work environments.

In the beginning, Tempest produced inflator fans for hot air balloonists and now manufactures a wide variety of ventilation tools used by firefighters around the world to make their work environments safer. 

The technique of Positive Pressure Ventilation (PPV) has revolutionized the way hazardous interior environments are controlled and ventilated. Whether the structure is a 1,000 square foot home, 30-story building or mile-long tunnel, Positive Pressure Ventilation can be used to quickly replace a hostile interior environment with clean, fresh air.
 

Tempest offers a comprehensive line of gasoline, electric and hydraulic powered blowers designed for a variety of emergency ventilation applications.

Additionally, Tempest VentMaster Fire Rescue Saws and Raptor Carbide Chains are used by thousands of fire departments around the world for vertical ventilation operations.
 

• Belt-Drive systems help absorb  engine vibration, preventing the blower  from “walking” during operation on  smooth surfaces.
• The Belt-Drive pulleys are tuned to  precisely match the horsepower  and torque of the engine, maximizing  performance.
• Belt-Drives allow the engine to be  set lower in the frame, improving
stability and minimizing disruption of  the airflow.

Tempest Direct-Drive blowers evolved from the “Controlled Airstreams” line of durable PPV blowers; the first direct-drive PPV’s and still the best. Available in 16” to 24” diameter sizes, there is a Tempest Direct-Drive to match your budget and compartment space. For the best combination of performance, compact size and light weight, choose a Tempest Direct-Drive. The impeller is mounted directly to the engine shaft, reducing the blowers overall weight. Vibration problems that are common to most direct-drive blowers have been minimize with the use of overhead valve engines, precisely balanced impellers, and vibration-absorbing feet. The direct-drive design is more compact to provide a smaller profile for storage in most apparatus compartments.

The VentMaster line of chain saws feature the New Husqvarna Pro 576HD Power Head, the most advanced power head available for fire service operation.

The Husqvarna Pro 576HD is the most advanced power head available for fire
service operation. With higher peak power and 20% more torque, the 576HD provides maximum cutting power over a longer range while improving productivity. The new One Step Starting, which combines the choke, throttle lock and stop mechanism all in one switch, eliminates flooding and allows fast convenient starting. The Raptor Carbide tipped chain was engineered to withstand the rigors of fire service operation. The Raptor cuts quicker and lasts longer than bullet chain or single raker carbide chain.

Tempest has combined the 576 HD and the Raptor Carbide Chain to provide you with a winning combination:  faster cuts, higher peak power, less maintenance and improved user productivity.

The 375K Cutoff Saw incorporates features found on no other Cut Off Saw on the market today. This lightweight unit provides for maximum Power, Versatility and durability. 

Smoother operation, reduced wear: The 375K features the most advanced air intake filtration and cooling system available today. The patented "Centrifugal Force" Active Filtration System mechanically filters 97% of airborne contaminants, preventing premature clogging. The cleaning system allows for longer intervals between filter cleanings and provides for smoother operation and reduced wear.

Fast, Easy Starting: The unique Decompression valve reduces piston pressure during starting. The valve reduces required pulling force therefore making starting easier and reducing wear on starter parts. The large D-Ring Starter Handle and One Step Starting make the 375K faster and easier than the competition.

Versatility for Tough Cutting Jobs: The high-power and wide torque enables this saw to work with large diameter cutting discs for greater cutting depths. The reversible cutting arm allows for cutting in close, confined spaces. With its slim saw body and high center of gravity the 375K is handy and easy in tough situations and harsh environments.

The 396K Cutoff Saw is the newest addition to the Ventmaster line of durable cutting tools for the fire service. Incorporating features found on no other fire/rescue cutoff saw, the Ventmaster 396K meets the needs of today’s fire service personel.

Stability Like no Other Saw: The 396K features a 1.5” diameter by 7” wide saw support roller attached underneath the engine head to provide for more stable operation and to support the weight of the saw during long trench cuts. Also provides leverage during plunge cuts.

Fast, Easy Starting: A compression release button reduces the amount of force required to get the saw started. A D-Ring Starter Handle makes the saw easy to crank while wearing heavy gloves.

Versatility for Tough Cutting Jobs: A 180-degree reversible cutting arm allows cutting within one inch of walls, curbs, or vertical obstructions. Ideal for tight confined space situations that require awkward cutting angles.

The 3120K Cutoff Saw - This 119cc saw is one of the most powerful handheld power cutters. The 3120K has a rugged and powerful engine that can handle deep cutting applications with blade diameters up to 16". 

Air Injection: Centrifugal air cleaning system for longer intervals between filter cleanings, smoother operation and reduced wear.

Fast, Easy Starting: A compression release button reduces the amount of force required to get the saw started. A D-Ring Starter Handle makes the saw easy to crank while wearing heavy gloves.
