What Tempest Technology Corp does

Tempest Technology Corp is a Fresno, California-based private manufacturer of professional firefighting, rescue, industrial ventilation, foam, safety, and training equipment. It serves municipal fire departments; industrial and commercial facilities; specialized search-and-rescue teams; fire-training organizations; agricultural operations; and military and emergency-response units. The company has operated for more than 40 years and became part of Leader Group in 2018.

Core products include positive-pressure ventilation fans, mobile ventilation apparatus, smoke ejectors, hydraulic and explosion-proof fans, fire pumps, compressed-air-foam systems, rescue saws, thermal cameras, MULTISEARCH radar, seismic, and camera systems, structural-stability monitors, and fire-simulation equipment. Disclosed engineering features include custom axial impeller blades, hydraulic fan, tilt, and scissor-lift systems, a Mobile Ventilation Unit with up to 150,000 CFM airflow, battery fans rated up to 11,000 CFM for 70 minutes, and compatibility with MILWAUKEE, DEWALT, HURST, and Husqvarna battery systems. Tempest's Mobile Ventilation Units are designed, fabricated, and hand-built in the United States at its Fresno facility.

Tempest primarily generates one-time equipment revenue. Higher-value apparatus is sold through an exclusive authorized-dealer network that provides consultation, installation, and post-sale support, while e-commerce covers smaller equipment, accessories, consumables, and replacement parts. Prices range from under $100 for accessories to $1,500-$10,000 for standard fans, $24,000-$40,000 for MULTISEARCH kits, and $51,750 for a foam trailer; installation and training can be sold separately. Sourcewell Contract #020124-TEM supports government and nonprofit procurement. The business model therefore combines dealer-led project and apparatus sales, direct e-commerce, and an aftermarket for parts and batteries; no subscription or contracted recurring-revenue stream is disclosed.
