NP4DLM – Navtek BreakFree® Cordless Vacuum Pump 4 CFM – More Power, More Freedom, More Performance

The Next Generation of Cordless Vacuum Power

The Navtek NP4DLM BreakFree® Cordless Vacuum Pump is the third model in the award-winning BreakFree® Series — and the most powerful yet. Designed for residential and light commercial HVAC applications, the NP4DLM delivers 4 CFM of evacuation performance in a cordless, portable package that goes wherever the job takes you. It is also A2L refrigerant compatible, making it ready for the next generation of low-GWP refrigerants.

Brushless DC Technology for Superior Efficiency

The NP4DLM is powered by a 1/2 HP brushless DC motor — delivering higher efficiency, longer motor life, and more consistent performance than traditional brush motors. Brushless technology means less heat, less wear, and more reliable operation in the field.

4 CFM Dual-Stage Performance to 15 Microns

With a 4 CFM flow rate and dual-stage pump design, the NP4DLM achieves an ultimate vacuum of 15 microns — exceptional performance for residential and light commercial system evacuations. Whether commissioning new systems or performing deep vacuum on existing equipment, this pump has the capability to do the job thoroughly and efficiently.

High-Performance 18V 9.0Ah Lithium-Ion Battery

The included NBP2 18V 9.0Ah lithium-ion battery delivers up to one hour of continuous running time — enough capacity to handle full evacuation jobs on a single charge. The higher 9.0Ah capacity is a significant step up from standard battery packs, giving you more runtime and fewer interruptions on the job.

Truly Cordless — Work Anywhere

Designed for technicians who work in real-world conditions — rooftops, confined spaces, remote plant rooms — the NP4DLM cuts the cord entirely. No power outlet required, no extension leads, no limitations. Set up in seconds and get straight to work.

Isolation Ball Valve and Backflow Prevention Check Valve

The built-in isolation ball valve lets you isolate the system at the pump without breaking the vacuum, while the backflow prevention check valve protects your work if the pump stops unexpectedly — giving you complete control and peace of mind throughout every evacuation.

Gas Ballast for Better Moisture Handling

The NP4DLM includes a gas ballast — a valuable feature for jobs where moisture contamination is a concern. The gas ballast helps prevent oil emulsification and allows the pump to handle moisture more effectively, extending oil life and protecting pump performance.

Lifting Hook for Easy Positioning

The integrated lifting hook makes it easy to hang, position, or rig the NP4DLM in hard-to-reach locations — a practical feature that makes a real difference on commercial jobs where access can be challenging.

Compact, Lightweight, and Easy to Carry

Despite its impressive performance, the NP4DLM weighs just 15.4 lbs with battery and measures 12.4″ × 4.4″ × 9.4″. The included heavy-duty travel tool bag keeps everything organised and protected between jobs.

Everything You Need, Right Out of the Box

The NP4DLM kit includes the vacuum pump, NBP2 9.0Ah battery, NC2 charger, oil dispenser, and heavy-duty carry bag. The NAPS1 power supply adapter is available separately for those who need corded operation as a backup.
