Every extra piece of equipment on a rescue apparatus creates another battery platform to manage, another charger to monitor, another thing that can go dead at the worst possible moment. For departments already running HURST Jaws of Life extrication tools, the standard battery-powered PPV fan has always been exactly that kind of redundancy problem. The … Read more

Fire departments have been burned before by proprietary battery ecosystems: a battery PPV fan arrives on scene, its custom cells are depleted, and there is no compatible charger on the rig. The Tempest VS-1.2D solves that problem in the simplest way possible. It runs on the same DEWALT FLEXVOLT 20V/60V MAX 12.0 Ah batteries that … Read more

Confined space entry failures rarely happen because the work crew was careless. They happen because the ventilation equipment was too large to position correctly, too weak to clear a deep vessel before entry, or simply not rated for a flammable atmosphere. The Tempest EBS-16 was engineered around exactly those failure scenarios: a 16-inch fan compact … Read more

A gasoline saw that won’t start in the first ten seconds of a roof ventilation operation is not a tool problem. It is a tactics problem. Crews lose those seconds to priming, choking, and pull-cord attempts while smoke conditions deteriorate below them. The Tempest VentMaster K1 removes that variable entirely. Battery power means the saw … Read more

Most portable ventilation fans top out between 10,000 and 20,000 CFM. That ceiling is acceptable for residential structure fires or small confined spaces. It is not acceptable when you are trying to clear a 500,000-square-foot warehouse filled with smoke, purge a rail tunnel after a chemical release, or ventilate a multi-level industrial facility where a … Read more

A standard consumer chainsaw was never designed to cut through nail-embedded roof decking at 0200 hours with smoke obscuring your sightline and seconds mattering. The wrong saw stalls on composite materials, buries its bar in debris-packed cuts, or lets a firefighter over-penetrate a roof that cannot bear the extra weight. That specific set of problems … Read more

Every second a fire company spends hunting for a working outlet, untangling extension cords, or diagnosing a slipping belt drive is a second smoke stays inside a structure. Positive pressure ventilation works only as fast as the fan you can deploy, and the fan only performs as advertised when the power path between engine and … Read more

Roof ventilation under live fire is not the place to discover that your saw bogs out at depth, your blade selection was wrong for the substrate, or your cut went three inches deeper than intended into a utility chase. Fire departments have lost firefighters to exactly that kind of equipment failure. The Tempest VentMaster 375K … Read more

Positive pressure ventilation on a working structural fire does not wait for an extension cord. When crews are pushing smoke out of a two-story residential or clearing a confined industrial space, a gas-powered PPV fan introduces fuel load and exhaust into the equation at exactly the wrong moment. Battery-powered fans solve that problem, but most … Read more

Gasoline PPV fans move serious air, but they come with real trade-offs: exhaust fumes inside a structure, fuel logistics, combustion noise that drowns radio communication, and outright prohibition in any environment with flammable vapors. The Tempest Variable Speed Electric PPV Fan series was designed to close that performance gap. With up to 15,663 CFM from … Read more
