Navtek 18V Li-Ion Battery 5Ah (NB1)

Suitable for residential and light commercial applications, the new NP4DLM can achieve a flow rate of 4 cfm among other attributes. The model is the third unit in the BreakFree Series™ of cordless HVAC tools.

The NP4DLM Cordless Vacuum Pump features a high-performance lithium battery capable of up to one hour of continuous running time. At a scant 15.4 pounds, the unit is exceedingly efficient and, for technicians, easy to carry and store. The NP4DLM's twin cylinder operation provides high vacuum down to 15 microns. A check valve prevents backflow. Other highlights include an isolation valve as well as a lifting hook and gas ballast for better moisture handling. Its inlet port fits flares of 1/4", 3/8", and 1/2".
