Review on 🔧 NewPosition 4CFM 1/3HP Air Vacuum Pump: Ultimate HVAC A/C Refrigeration Tool Kit for AC and Auto Repair with Manifold Gauge Set, R134A R22 Compatibility, and 3 Hoses by Tony Wilson

One of my sandwich fridges broke last week due to a lack of freon. I decide to get him back to work on my own. All I need is to add 9.5 ounces of R134a to the unit. I know I need a vacuum pump to get the job done. If I find a bulletproof valve leaking, I replace it immediately. Close the manometer attached to the vacuum pump, fill in the pump oil (not included in the scope of delivery), switch on the device, wahhhh. It took me less than 4 minutes to create a deep vacuum which is very impressive. After making sure there are no leaks in the system, look at the manifold pressure gauge. Freon charge. Took me about 30 minutes to get the job done. I would definitely recommend this product to anyone who needs a vacuum pump to get the job done. It would have been even better if the seller had provided him with a bottle of pump oil.
