Howden American Fan Company, a manufacturer of high-quality industrial fans and blowers, has launched its new ventilation concept for underground parking garages that includes two alternative options – the Jet Thrust Fan and the Induction Thrust Fan.

The new system lowers the required parking garage height by about 4 ft, reducing excavation and cement costs and lowering overall construction costs. It replaces traditional ducted garage ventilation distribution with a number of small ceiling-mounted fans.

“Parking garage fan systems are one of the most cost-effective ways to ventilate, both in terms of installation cost and long-term running costs,” says Rae Jane Araujo, technical sales manager, Howden Industrial Fan Group.

“In addition, minimising clearances between ceiling height and cars and trucks can really reduce construction costs,” he adds.

The Jet Thrust Fan option features small ceiling-mounted Underwriters Laboratories (UL)-certified units, with silencers, hangers, and deflectors. The fan can be equipped with optional reversible flow capability for emergency smoke ventilation and access for fire personnel.

The alternative Induction Thrust Fan option, on the other hand, features small ceiling-mounted UL-705 certified units with an even smaller height profile than the Jet Thrust Fan. The fans are used for ventilation, and as noted, reduce construction costs and require lower building heights. 

Howden supplies axial fans, centrifugal fans, which can be installed in the optimum location to distribute the airflow to all areas of the parking garage, ensuring removal of any stagnant air.

The Jet Thrust/Induction Thrust fans are controlled to detect pollution and activate only as needed to meet required pollution thresholds. The system can be zoned, so all fans do not have to operate at the same time.

Howden supplies axial fans, centrifugal fans, and blowers for a wide range of industries, including marine, industrial manufacturing, and building and construction. Located near Cincinnati, the US, Howden American Fan is part of the Howden Industrial Fan Group, made up of American Fan, Joy Fan, and Garden City Fan.
