Review: Lemons may exist - mine worked great - I read the negative and average reviews. I was really concerned about buying a potential $60 paperweight. I used this way too many times in the past two weeks and am very satisfied with the results. Drop test - passed. Multiple uses - pass. Recommend - yes. I had an accumulator’s schrader valve stick which caused a leak. I have tools to replace the valve while leaving the system pressurized, but this required the accumlaotor to accept the valve and the replacement schrader valve to also be good. Fail and fail. Anyways enter the replacement accumulator and first attempt. The pump worked great and pulled a perfect vacuum. The motor was hotter than expected, but no issues. Charged the system and everything was roses and smiles. Two hours later and after a loud sound of rushing air, I discovered a spring fitting on the new accumulator failed and I lost my charge. Reset the connection and it passed the pull apart test. It appeared solid. Vacuum number 2 - worked great. I turned after pulling the vacuum and promptly sent the pump off the radiator falling to the ground. I got lucky with no damage to the pump or gauges. The gauge line sort of softened the fall. I began to recharge the system. One can in and I had to deal with another issue. Pop goes the same spring connection. Lesson one: don’t buy crap aftermarket AC stuff. Poor quality control. Bought a Motocraft and installed it. (Fit perfect) Vacuum number 3 and everything is still working great. The pump ran for over three hours in 95+ degree weather over the three vacuums. No noticeable oil loss. Solid vacuum. Met my needs and then some. I suspect there will be lemons in any process, but this one worked very well for my needs. ## Features - ✅High Performance - The Kozyvacu Vacuum Pump for AC repair tools delivers excellent performance with a high flow rate of 3.5 CFM, making it a perfect choice for Car AC or HVAC applications. - ✅Versatile - This vacuum pump is versatile, ideal for both workshop applications like HVAC, Auto AC, and automotive systems, and widely used in household and commercial tasks such as refrigeration maintenance, printing machinery, and vacuum packaging, e-poxy resin degassing, wine degassing, thermoforming. - ✅Easy to Use - The vacuum pump comes with an AC vacuum pump kit, making it easy to set up and use.

It has held up well with regular oil changes. HOWEVER, the best vacuum I can pull is 130 microns with a CPS VG200 connected directly to the pump. While anything under 500 microns is considered acceptable, the rating plate on the pump claims to be able to pull down to 37.5 micron (5pA). It does the job to get well below what is considered acceptable vacuum in the automotive and residential HVAC industry, however it would be nice to have a specification plate that is actually true. I'll ding a star for that, but have nothing else negative to say. Decent little pump for the money. ## Frequently Bought Together - Kozyvacu Single-Stage HVAC Vacuum Pump, 3.5CFM - Ideal for AC Repair Tools, Car AC Vacuum Pump, AC Vacuum Pump Kit, and Recovery Machine HVAC - Also Known as Bomba de Vacio A/C (TA350) - TSI Supercool Vacuum Pump Oil, Synthetic, 32 Oz., Clear (V32) - Refrigeration Technologies RT201B Nylog Gasket/Thread Sealant, 30 ml (1 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/39477144-single-stage-hvac-vacuum-pump-3-5cfm-ideal-for-ac](https://www.desertcart.co.uk/products/39477144-single-stage-hvac-vacuum-pump-3-5cfm-ideal-for-ac) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-11*
