Vacuum is not emptiness. It is leverage. Every refrigeration circuit, every sealed system, every quiet compressor depends on one invisible act performed before the gas ever moves: the evacuation. The Evac Pro is the tool that performs that act with laboratory-grade discipline, pulling moisture and non-condensables out of a system so the refrigerant can do its work in a clean, dry, honest environment.
Engineered as a single-stage vacuum pump for professional HVAC service, it pairs a 180W motor with a 3.6m³/h pumping rate and a 2Pa ultimate pressure. That means deep evacuation when it matters, not just a token pull. The integrated high-accuracy vacuum gauge keeps you honest about system pressure, while the automatic anti-backflow valve protects the pump and the system from contamination when you power down. A large sight glass lets you monitor oil level at a glance, and the 7/16"-20UNF inlet threads connect cleanly to standard manifold gauge sets.
This is the machine that refrigeration technicians, appliance repair specialists, and HVAC workshops reach for when a sealed system will not hold. It handles R410A, R407C, R134a, R12, and R22 with equal composure, which makes it a single investment that follows you across decades of equipment generations. For printing machinery, vacuum packaging lines, gas analysis, and thermoplastic molding, it is equally at home.
Consider what a proper evacuation actually buys you. Moisture left inside a sealed system turns into ice at the expansion valve, acid in the oil, and corrosion on the compressor windings. Non-condensable gases raise head pressure, throttle capacity, and shorten the life of every component downstream. A pump that reaches deep vacuum quickly is not a luxury; it is the difference between a repair that lasts and a callback that haunts your week. The Evac Pro is built for that standard of work, with a design that keeps oil from migrating into the system and a gauge that tells the truth about when the job is done.
This is not a pump. It is the quiet ritual that makes every sealed system trustworthy again.

Where It Belongs
The Evac Pro belongs wherever sealed systems are serviced: refrigeration repair benches, automotive AC workshops, HVAC maintenance trucks, and vacuum packaging floors. It is the first tool reached for when a system loses vacuum or a compressor replacement demands a clean pull. Note that vacuum pump oil is not included due to air-freight restrictions, so confirm local oil availability before you begin.
Frequently Asked Questions
Q: What refrigerants does this pump handle?
It is compatible with R410A, R407C, R134a, R12, and R22, covering the most common residential and light commercial refrigerants in service today.
Q: What is the ultimate vacuum level?
The pump reaches 2 Pa ultimate pressure, deep enough for professional evacuation of sealed refrigeration systems.
Q: Is the vacuum gauge accurate?
Yes, the built-in high-accuracy gauge reads actual system pressure so you know exactly when evacuation is complete.
Q: Does it include vacuum pump oil?
No, pump oil is excluded from shipment because of air-freight regulations. Purchase compatible vacuum pump oil locally before use.
Q: Can it be used for vacuum packaging?
Yes. The 3.6 m³/h pumping rate suits vacuum packaging, gas analysis, thermoplastic molding, and printing machinery applications.
Q: How often should I change the pump oil?
Change the oil every 10 to 15 operating hours or when it appears milky or contaminated. Fresh oil keeps ultimate vacuum performance consistent.
Q: How should I store the pump between jobs?
Keep it in a dry place with the inlet capped. Run it briefly with the inlet open to purge moisture if it has been idle for weeks.
Q: Can it pull vacuum on automotive AC systems?
Yes, the 2 Pa ultimate vacuum and 3.6 m³/h pumping rate are well suited to automotive AC evacuation, where deep vacuum removes moisture before recharge.
