Positive Pressure Ventilation fans

Based on our high-performance positive pressure ventilation fan designs used in firefighting around the world, the 24-IND showcases some of our best work: A low profile roll cage frame, high CFM output shroud, blade, engine and a number of features which make it incredibly easy to move, adjust and store. Most importantly, the 24-IND is able to perform PPV, the most efficient and effective means of ventilating structures.

Welded Steel Roll Cage Frame

Every bend and cross brace weld is structurally engineered to give the fan’s frame more strength and durability, improving its strength to weight ratio by as much as 30%. The frame is specifically designed to give protection to nearly all angles and sides of the shroud and motor, and doubles as a handle for lifting/carrying.

Single Speed Or Variable Speed Motor

The 24-IND comes standard with a single speed electric TEFC motor with an output of 1.0 HP or the option of being equipped with a 2.0 HP variable speed motor. The specific motors are both matched perfectly with the fan blade’s size and pitch to produce the most effective air movement possible.

High CFM Output

Due to the applications in which they are needed, Tempest fans feature some of highest CFM (Cubic Feet per Minute) measurements possible in a midsize mobile unit; the 24-IND is no exception. The blades are designed specifically for the 1 HP motor the fan uses to allow for the greatest performance possible. The enclosed shroud directs the air pattern over greater distances towards the desired location. When looking to ventilate an area in high risk environments, you can’t afford not to go with a Tempest.
