Dry Air Pumps: Tempest offers a complete line of new and overhauled dry air pumps. Tempest pumps are FAA-PMA approved and meet the demands of today’s light aircraft. 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, our 240 and 400 series dry air pumps are designed with today's 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. Tempest larger pumps also use hardened stainless-steel pressure plates that are precision ground and lapped to reduce internal leakage and wear.

Stand-by Systems: Tempest manufactures the only FAA-PMA approved stand-by AP8-100 kit for Cessna Caravans.  Tempest's auxiliary dry air pump system provides an independent backup vacuum source to operate the gyro flight instruments in the event of unscheduled maintenance to the bleed air vacuum system.  The AP8-100 kit includes the AA4A2-1 electric stand-by pump, the AP8-100-20 manifold valve, fittings and hardware.  For a complete list of AP8-100 kit parts please see AP8-100 Caravan STC Kit.
