Oil-Free DC Electric Air Compressor/Vacuum Pumps
 |  |
Style A | Style B |
Generate only as much compressed air or vacuum as you need for precise control in low-flow applications. These pumps deliver a stable output without large fluctuations, so they’re an energy efficient choice. Use a vehicle battery or a DC generator (both not included) to power them. Since they don't require lubrication, there’s no risk of oil contamination in the air.
These pumps come with two ports: one for pressure and one for vacuum. To switch from an air compressor to a vacuum pump, disconnect from the outlet port and connect to the inlet. Make sure the outlet port is open to atmosphere or vented.
24V DC—NPT Female Inlet and Outlet
|
Style A |
Style A—Style A pumps are built for rugged environments. Use them in a variety of power applications—from air brakes to septic aeration systems. Since they’re manually actuated and lack a relief valve, you’ll need to monitor their operation to prevent pressure buildup.

24V DC—BSPT Female Inlet and Outlet
|
Style B |
Style B—Style B pumps generate air for delicate suction and gripping common in robots, medical devices, and industrial automation. A digital pressure switch and relief valve automatically turn them on or off based on pressure levels. Use the included brackets to mount their controller on a 35 mm DIN rail.
