“We now save hundreds of thousands annually on unnecessary filter replacements and produce a more controlled environment for the troops.”


A major supplier of ventilation/pressurization units for various tent-based systems (i.e. medical aid, mobile hospital, troop quarters, etc) was experiencing excess premature filter replacement demands caused by filtered particle build up. The ventilation units are required to deliver a constant airflow and as the back pressure increased, the only in-field solution was to replace the filter. Invention House solved this problem by creating a custom drive solution which had 50% more horsepower and could maintain the airflow against higher filter back pressure. The result: a dramatic decrease in filter replacement, saving the military time, money and decreased shipping and inventory of filters plus the added benefit of a greater range of deployment.

Customer Comment


“Invention House Drives do not fail.”


The SPAWAR division of the US Navy was unable to procure a 400Hz power converter because it was discontinued by the original manufacturer. The converter drives cooling fans in the precision approach radar system used at Naval air stations such as Camp Pendleton and NAS Pensacola. In 1 month, Invention House designed and delivered a converter that met the form, fit, and function requirements. In addition, the new converter is current limited and will not burn out like the old unit. Since development, Invention House has delivered over 60 units, saving the government hundreds of thousands of dollars in the first year alone.
