## Questions & Answers

**Q: What fitting is on the vacuum side? npt? flare? some special fittings that i haven't learned about yet?**
A: I used standard air line fittings.

**Q: Where does the vacuumed refrigerant go?**
A: This unit it to put a vacuum. Not to remove the pressurized system.
My ac system on jeep had a bad pipe. No pressure.  I replaced pipe the used this to get a vacuum in ac system prior to recharging.

**Q: Does this evacuate the ac system?**
A: It pulls a vacuum on the system just before recharge.  This is not to collect the Freon.

**Q: Does it pull the freon or just to pull the air out?**
A: No it does not pull the freon you need to take it and have that done.  It only pulls the moisture and air out after opening up the system

## Customer Reviews

### ⭐⭐⭐⭐⭐ Small and light, works well
*by T***T on July 5, 2025*

Compact, light, trouble free, lots of vacuum.

### ⭐⭐⭐⭐ Got the job done
*by M***. on June 20, 2025*

Was what we needed for our mini split installation. No issues but the unit is very light weight plastic and pot metal. Not sure how much pressure it will take. Reasonably priced solution for our project.

### ⭐⭐⭐⭐⭐ Simple little vacuum pump
*by C***S on January 23, 2020*

I bought this for the occasional project where I need to vacuum bubbles out of silicone or epoxy and it works well. I actually removed the "mechanism" out of the case for simplicity, and mounted it to the side of my vacuum pot. It's just a simple all plastic venturi vacuum pump so it is quite minimal inside. I bought this over an actual vacuum pump, as I already have a compressor, and don't need to have it operated for long periods so I didn't need a dedicated vacuum pump. I've got a 100 gallon compressor, and I think my compressor is a bit on the weak side, so after like 10 minutes of constant flow / vacuum, I start to drop pressure in my tank, and this pump needs 90 psi of inlet pressure to maintain the 30 psi of vacuum. I'm going to add a valve between my pump and tank, so that once I reach my 30 psi of vacuum, I'll hold the internal vacuum and recharge my compressor.
