Each new FAA-PMA approved Tempest dry air pump is meticulously and professionally hand assembled to insure proper tolerances and clearances. This assures optimum performance. After assembly, each pump is functionally tested. After this initial testing, the pump is then disassembled, inspected for any unusual wear or abnormalities, and reassembled for a second test run. This extensive testing procedure assures that only first-class products leave our facility.

All new and overhauled Tempest dry air pumps come with Tempest’s patented WIP™ (Wear Indicator Port) that allows for internal observation of the pump’s vanes.  The WIP™ helps determine if the pump should be replaced and avoid unscheduled maintenance due to a pump exceeding its life cycle.  Tempest pumps also include finned stators for increased cooling and an “ultra-hard” finish on the internal wear surfaces of the stator for low friction and extended life.

Tempest new dry air pumps offer a closed coupling area and patented “LRT” diverter.  These design features will help you detect and prevent pump contamination from external sources.

Rugged and lightweight, the 240 and 400 series dry air pumps are designed with todays high performance aircraft in mind.  These pumps use a heat-treated, stainless-steel conical pressure plate spring and torsional dampening springs to provide a harmonics-free pressure plate control and smooth temperature compensation.  Larger Tempest pumps also use hardened stainless-steel pressure plates that are precision ground and lapped to reduce internal leakage and wear.
