Side-by-side: Comparing Core Products
Let’s look at the head-to-head competition in the most important tool categories.
Vacuum Pumps
Vacuum pumps are critical for system evacuations. If you cut corners here, you risk callbacks and system failures.
| Feature | Navac NP2DLM Cordless | Fieldpiece VP67 |
|---|---|---|
| Pump Type | Dual-stage, cordless | Dual-stage, corded |
| Flow Rate | 2 CFM | 6 CFM |
| Weight | 8.4 lbs | 24 lbs |
