❄️ Economy Single Stage Refrigerant Conditioning Solution by ZENY Review

Worked great for the first few weeks. I haven't used it for a few weeks and all the oil has leaked out. I've tried to tighten the screws on the bottom to no avail, this thing has a slow mysterious leak draining the entire case.

This pump only lasted two months with infrequent use, after which it stopped working. When it worked, it was very efficient and pretty quiet. I would recommend this pump if it weren't for the fact that you may need to replace it shortly after purchase.

This is a single stage toy pump but for the price it actually works quite well. The compliance label states an ultimate vacuum of 5 Pa (or approximately 37.5 microns). I get about 120 microns with just a thermocouple sensor. Like most pumps, it will bubble up and spit out some oil when pumping a gaseous charge. A small trap will prevent this, I'll probably build one for that. I suspect the supplied oil is not a very good vacuum oil. It has a distinct odor, which is generally a bad sign if you…

The pump worked well the first few times I used it. He did the job I bought him for. It wasn't the right attachment for what I wanted to do with it, which is a car air conditioner vacuum cleaner, but I knew that beforehand. The PROBLEM comes from the fact that this thing loses oil terribly. I've used it a few times after buying it in September, but at the end of October I spoke to ZENY customer service about how much oil was leaking from this thing. From the bottom of the device, as well as…

I've never worked with AC before and thought it was time to give it a try. The compressor ended up failing on a 2003 250,000 mile expedition. I bought a replacement compressor, set of pressure gauges and vacuum pump from Revain. All items arrived as planned. A vacuum pump is required after installing a new compressor. I hooked up the vacuum pump to a set of gauges using simple fittings that came as part of the pump and connected the gauge fittings to the refrigerant lines under the hood. The…

I bought it 1 year ago. I've seen probably 3 hours of use in half a dozen different TSF and fiberglass cures. It was ok but uses a decent amount of oil. As my first vice president, I don't have a basis for comparison, so maybe that's okay? Consumption is less of an issue than the fact that oil is shot vertically in a 1 foot diameter around the pump outlet. I set him on a platform made of shop towels to soak up some of the oil. The oil in it has been used up and almost gone, so it's time to buy…

This is a really great little vacuum pump. It vacuums quickly and relatively quietly. It doesn't take up much space, so it doesn't take up much space! - 1 star due to oil leaks as others have mentioned. However, unlike others, I had no trouble contacting and communicating with the support team. They asked relevant questions and provided simple information so they could help me. They offered to refund 50% of the purchase price for my issues, which I didn't think was necessary if a replacement…
