NP7DPF – Navtek Vacuum Pump for Flammable Refrigerants – Powerful, Safe, and Built for A3-Class Environments

Designed Specifically for Flammable Refrigerants

The NP7DPF is a powerful and reliable vacuum pump designed specifically for use with flammable refrigerants, including A2L, A2, and A3-class refrigerants such as propane, butane, and other hydrocarbons. As demand for A3-class refrigerants grows across the industry, the NP7DPF provides a purpose-built solution for technicians who need to handle and process these refrigerants safely and effectively.

Explosion-Proof Motor with Sparkless Power Supply

Equipped with an explosion-proof motor and a fully spark-free design, the NP7DPF ensures safe operation even in hazardous environments where flammable refrigerant vapours may be present. The sparkless power supply eliminates ignition risk at the source — a critical safety feature when working with A2 and A3-class refrigerants.

Certified to International Safety Standards

The NP7DPF has been designed and tested to UL 121201, CSA C22.2 No. 213-17, and IEC 60079-7 standards — the internationally recognised benchmarks for equipment used in explosive atmospheres. Technicians and businesses can deploy the NP7DPF with confidence in compliance-sensitive environments.

Dual-Stage Design for High Ultimate Vacuum

The dual-stage pump design achieves an ultimate vacuum of 15 microns — delivering the deep, thorough evacuation required for professional HVAC&R system preparation. The integrated cylinder structure further enhances performance and long-term reliability, reducing the risk of wear and failure over time.

7 CFM Flow Rate for Fast Evacuation

With a 7 CFM flow rate driven by a 3/4 HP AC motor, the NP7DPF moves volume quickly to reduce evacuation time on the job. Three inlet port sizes — 1/4″, 3/8″, and 1/2″ Flare — provide flexibility to connect directly to a wide range of hose configurations without adaptors.

Forced Oil Circulation for Improved Efficiency and Durability

The forced oil circulation system ensures consistent lubrication throughout the pump mechanism, improving thermal efficiency and extending the service life of internal components. Combined with the oil-mist filter, this keeps the pump running cleanly and efficiently across extended use.

Oil-Mist Filter, Gas Ballast, and Lifting Hook

The NP7DPF comes equipped with a built-in oil-mist filter to reduce oil vapour exhaust, a gas ballast to assist with the removal of moisture and non-condensable gases during evacuation, and a lifting hook for safe and convenient handling of this 26 lb pump on site.

Important: Prohibited Refrigerants

This product is PROHIBITED for use with IIB and IIC refrigerants, including RE170, R702, R1150, R429A, R432A, R435A, and R510A. Do not leave the pump running unattended in a closed environment without adequate ventilation.
