The Unsung Hero of Your Tool Bag: The ECQ VP115 Vacuum Pump
If you work in refrigeration or air conditioning—whether you are fixing a small fridge in a local shop or installing a split system in a new apartment—you know that moisture is the enemy. It is the silent killer of compressors. You can have the best welding skills in the world, but if you leave air inside the pipes, that unit will fail.
This is where the ECQ VP115 comes in. It is not the biggest pump on the market, but for an artisan bricoleur or a technician on the move, it is often exactly what you need. It is compact, it is reliable with its 100% copper winding, and it pulls a vacuum deep enough to degas a system properly before you recharge with R134a or R410a.
Why 2 CFM Matters for Small to Medium Jobs
Many technicians think “bigger is better,” but that isn’t always true. A huge 8 CFM pump is heavy and can actually pull a vacuum too fast on small capillary systems, causing moisture to freeze before it boils off. This 2 CFM (50 L/min) pump is the “Goldilocks” size—perfect for:
- Domestic Refrigerators (1/5 HP to 1/3 HP compressors).
- Split Air Conditioners (9000 to 18000 BTU).
- Car Air Conditioning systems.
It is light enough to carry up a ladder but strong enough to hit 5 Pa (approx 37 microns) of ultimate vacuum.
Technical Specifications: The “Heart” of the Pump
Here is the detailed breakdown of what this machine offers.

Comparison: VP115 (Single Stage) vs. Dual Stage Pumps
When you are deciding between a single-stage pump like this and a more expensive dual-stage unit, it helps to see the difference clearly.
| Characteristic | VP115 (Single Stage) | Typical Dual Stage (e.g., 2VP-2) | Verdict |
| Vacuum Depth | 5 Pa (Good) | 0.3 Pa (Excellent) | Single stage is fine for standard repairs; Dual is for deep-freeze/scientific work. |
| Weight | ~5 kg (Light) | ~10 kg (Heavy) | VP115 is much easier to carry to rooftops. |
| Price | Affordable | Expensive | VP115 offers better ROI for general repairs. |
| Maintenance | Simple Oil Change | Complex | Single stage is more forgiving with dirty oil. |
Performance Analysis: Speed vs. Quality
Let’s compare how this pump performs against other common sizes when evacuating a standard 12,000 BTU Split AC.
| Pump Size | Time to 500 Microns | Risk of Freezing Moisture | Best Use Case |
| 1 CFM (Small) | 45+ Minutes | Low | Very small fridges only. |
| 2 CFM (VP115) | 20-25 Minutes | Balanced | Residential AC & Fridges. |
| 6 CFM (Large) | 5-8 Minutes | High (if not careful) | Commercial chillers / Large VRF. |
Pro Tip: Always use a micron gauge. The sound of the pump changing pitch is a good sign, but it is not a measurement!
Maintenance & Troubleshooting
To keep your VP115 running for years, follow this simple maintenance schedule.
| Symptom | Probable Cause | Solution |
| Poor Vacuum | Dirty or low oil | Drain oil while warm and refill with fresh vacuum oil. |
| Oil Mist at Exhaust | Normal operation | This is normal when pumping large amounts of air at the start. |
| Pump Overheating | Low voltage or blocked fan | Check your extension cord gauge and clean the fan cover. |
| Hard Start | Cold weather | Warm up the oil or open the inlet port briefly to relieve pressure. |
