Miniature Oil-Free DC Electric Air Compressor/Vacuum Pumps
Our tiniest option—these DC-powered pumps generate compressed air or vacuum. Their low flow rate makes them a good choice for precise jobs—like medical device or electronics assembly—where too much force could damage components. 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.

Oil-Free DC Electric Air Compressor/Vacuum Pumps
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.
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.
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.
