NP4DP – Navtek Vacuum Pump 4 CFM AC Motor – Performance and Reliability in Every Pull

Built for Performance and Reliability

The Navtek NP4DP is a professional-grade 4 CFM dual-stage vacuum pump powered by a robust 3/4 HP AC motor. Engineered for performance and reliability, the NP4DP is designed to handle the demands of residential and commercial HVAC work — delivering deep, consistent vacuum on every job.

Twin Cylinder Design for High Ultimate Vacuum

The NP4DP features a twin cylinder configuration that works in concert with its dual-stage design to achieve an ultimate vacuum of 15 microns. This level of performance ensures thorough system evacuation, removing moisture and non-condensables effectively for long-term system reliability.

Integrated Cylinder Structure

The integrated cylinder structure is engineered for both high performance and long-term reliability — reducing vibration, improving efficiency, and ensuring consistent output over the life of the pump.

Forced Oil Circulation for Improved Efficiency and Durability

Unlike pumps that rely on passive oil distribution, the NP4DP uses forced oil circulation to actively lubricate internal components. This keeps the pump running cooler, reduces wear, extends service life, and maintains consistent performance even during extended use.

Large Oil Tank with Oil-Mist Filter

The NP4DP features a large 17 oz oil tank for extended operation between oil changes, and an oil-mist filter to prevent oil vapour from being discharged — keeping your work environment clean and protecting air quality on the job site.

Gas Ballast for Better Moisture Handling

The built-in gas ballast helps the pump manage moisture contamination more effectively, preventing oil emulsification and extending oil life — a valuable feature for jobs where system moisture is a concern.

Versatile Inlet Ports

With 1/4″, 3/8″, and 1/2″ flare inlet ports, the NP4DP connects easily to a wide range of manifold sets and HVAC systems, giving you the flexibility to tackle virtually any job.

Dependable AC Power

Running on 115V/60Hz AC power, the NP4DP delivers consistent, reliable performance wherever a power outlet is available — making it the ideal workshop or service van pump for technicians who don’t need to go cordless.

A Reliable Workhorse for HVAC Professionals

Compact enough to carry at 24.3 lbs and 14″ × 5″ × 11.3″, yet powerful enough to handle demanding commercial work, the NP4DP is a dependable everyday vacuum pump for HVAC technicians who expect performance they can count on.

⚠️ WARNING

Do not leave pump running unattended in a closed environment without adequate ventilation.
