The NP4DLM Cordless Vacuum Pump features a high-performance lithium battery capable of up to one hour of continuous running time. At 15.4 pounds, the unit is exceedingly efficient and easy to carry and store. Twin-cylinder operation provides high vacuum down to 15 micron, and a check valve prevents backflow. Other highlights include an isolation valve, a lifting hook and a gas ballast for better moisture handling.
