It’s pretty typical today to work on engines and transmissions with all battery-powered tools. However, when it comes to areas like Air Conditioning, that’s another story. When’s the last time you saw a cordless vacuum pump. Well, that’s our story today, we’re looking at the NAVAC NP2DLM cordless vacuum pump.

NAVAC NP2DLM Vacuum Pump

NAVAC NP2DLM Cordless Vacuum Pump Features

This NAVAC NP2DLM is a 2CFM pump that pulls down to 23 microns. Power comes from an 18-volt 5Ah battery delivering up to 45 minutes of runtime. In our testing, we measured just more than 42-minutes of runtime, so we call that close enough. You get a 1/4″ and 3/8″ flare inlet port, and of course a ball valve. The NP2DLM vacuum pump with the 5Ah battery is only 8-inches tall and 10-inches long. It weighs in at 8-pounds 9-ounces.

1/4″ and 3/8″ Flare Inlet Ports

A simple on/off button starts and stops the vacuum motor. We didn’t measure the decibel level with a meter, but the NAVAC NP2DLM cordless vacuum pump is well under the 85 dBA 8-hour limit set by OSHA. When you press the power button, there’s second or two delay before the motor starts and the motor ramps up to speed. This soft-start technology helps to protect electronics and other moving parts.

Final Thoughts

We used the NAVAC cordless vacuum pump on our 1971 Oldsmobile 442 muscle car project. We just installed a new Vintage Air system in the car, so it was a brand new line system to test the NAVAC NP2DLM. It was quite impressive to see this tiny and quiet vacuum pump pull down the system within minutes. This seems like a great solution for the mobile mechanic or even an industrial mechanic working on heavy equipment in the field. The price will run a little north of $500, and you get the NP2DLM pump, 5Ah battery, charger, and nylon carrying case. Check them out at NAVAC Global.
