About Tempest

Over three decades ago Tempest found its start in producing quality American made hot-air balloon inflators. Shortly after inception, we helped pioneer a new firefighting technique called positive pressure ventilation/attack or PPV/PPA. Our high-performance inflators were just what the fire industry was looking for to deploy this groundbreaking tactic. PPV became well known for its success along with Tempest’s reputation for being the first and only manufacturer with the perfect tool for the job at hand. In 2018 Tempest became part of the Leader Group family and is now able to offer a much more extensive range of products.



Very well established at the national level, Tempest Technology is one of the leading manufacturers of fire and rescue equipment in the USA. In 2017 the LEADER Group also one of the world’s leading suppliers of fire and rescue equipment purchased Tempest Technology. The LEADER GROUP is composed of 3 companies with complementary businesses: LEADER, BIOEX, and TEMPEST.


To deal with the evolution of fire risks and rescue missions, fire equipment must continuously evolve and adapt to be more efficient while ensuring maximum safety of end users. To meet these challenges, Tempest, a manufacturer of fire, rescue equipment, and industrial equipment has resolutely turned towards innovation and new technologies by integrating its own Research and Development team. Technologies and new products always developed with the end users in mind. Our equipment is continually evolving to keep up with technology and needs of our customers. To test equipment and evaluate their performance, Tempest utilizes LEADER in which continually invests in having its infrastructure loaded with the best facilities:
