Specs at a glance
Best for: Residential service techs who want one pump for most split systems.
- 6 CFM two-stage rotary vane, 1/2 HP AC motor
- 15 microns ultimate vacuum at the input ports
- 8 oz oil capacity with RunQuick oil change and ball-valve drain
- Backlit oil reservoir; quarter-turn gas ballast
- 29 lb (13.2 kg); 5.0 A nominal
Why it stands out
- RunQuick lets you change oil without shutting the pump off

Best for: Techs who work on larger systems or want the fastest pulldown in a light package.
- 10 CFM two-stage rotary vane
- 3/4 HP brushless DC motor, 2,500 RPM
- 15 microns ultimate vacuum at the input ports
- 8 oz oil capacity with RunQuick oil change
- 24 lb (10.9 kg), lighter than the VP67
Why it stands out
- 10 CFM at 24 lb
- Brushless DC motor and error messages for wrong power
- A2L certified
Keep in mind
- More pump than a light residential tech needs
What the listings say
- 8 CFM dual stage, 3/4 HP motor and 15 microns ultimate vacuum.
- Digital control with a built-in micron display, per NAVAC distributors.
- 17.6 oz oil capacity.
- A2L compatible, per NAVAC.
- Weight. About 25 to 28 lb, depending on the distributor.
Where it falls short
- Heavy. About 30 lb, which is a lot to carry up stairs.
- Warranty. Confirm the terms with the seller before you buy.
- Premium price. The Fieldpiece VPX7 lists 10 CFM at 24 lb, so compare before you buy.
Who should buy it
Techs who evacuate large systems and want a gauge built into the pump rather than a separate stand-alone unit. For lighter work, a 6 CFM pump is plenty.
How it compares
- Fieldpiece VP67 (6 CFM, 29 lb): lower price, oil change without shutting off, A2L certified.
- Fieldpiece VPX7 (10 CFM, 24 lb): faster and lighter, but without a built-in gauge.
- NAVAC NP2DLM (2 CFM, cordless): see the NP2DLM review.
Keep the oil clean
A pump with dirty oil will not reach its rated vacuum. With a capacity of 17.6 oz, the NRP8Di needs a regular oil change like any pump. Change it after contaminated jobs, store it capped and keep it level.
Where an 8 CFM pump pays off
More airflow shortens the time to reach a deep vacuum on long line sets and large coils, but the hoses and valve cores can limit the benefit. If you do big residential systems or light commercial work, 8 CFM is a reasonable step up from 6. If your jobs are mostly standard splits, the extra weight may not pay back.
