You should probably NOT lump all of the smaller compressors into one heading "cheap Chinese compressors". There are differences, and they can be bigly.

How to safely fill a tank from a home compressor
- Thread starter FlexWagtail
- Start date
Two things number one use steel fittings when dealing with pressures over 3K .. and stay back away from hoses etc as much as possible ...

To me the big things are to use good oil intended for use in high pressure compressors and add some cooling if your routine use will be filling good sized bottles. I fill my 45 minute SCBA bottle with my Yong Heng whenever I need to and it is working great after about 3 years of this use. I do not let the indicated second stage temperature go much over 60 C. With a radiator and fan on the motor I can fill my bottle from ~3000 to about 300 bar before I get to 62 degrees C. I doubt it would still be working if I used cheap oil in it and took it to 70 C or more regularly.

That is insanely impressive, I had no idea a YH could last that long. Good to know for people with limited options!

Many members use their 3+ year old Yong Hengs to fill bottles. In my case scuba bottles to 3k using coalescent filter followed by small media sieve filter for final air drying. The coalescent filter does a great job for primary moisture removal, water blast out that thing here in South Louisiana. Large 4.5k bottles take for time and sessions with ice bottle in my 4 gal bucket for recirculation. I also use Redline water wetter in lew of antifreeze for corrosion control. Cheers

I would love to have a premium air pump. I spend way too much for family travel. So, I justify $350 for cheap pump and filters that have served me well as long as it's dry and has accurate gauges. If you have mission critical needs or simply demand better, then boom up.

Never said there were free lunches. Just saying that quality varies among the more affordable compressors. Sometimes, the difference is BIGLY.

Just looked it up. Bought my YH 4/7/21. So well over 3 years. Pumped my 45 minute (66 ft3) from 3200 psi to close to 300 bar today in about 20 minutes run time without exceeding 61 C. No ice. Ambient in the room where the YH resides was about 30 C. Good oil and extra cooling are working. I also like my sealed bucket with water wetter in it. Much simpler to just hook the compressor to the bottle, turn on the cooling, and turn on the compressor. I have not changed the water in over a year.

I think so. It's been awhile since I filled the bucket. I check to be sure nothing is growing in the water occasionally and it still seems to be fine.

Less is more, when it comes to "coolant" ratios. The fact that you have used an anti-corrosive and anti-bacterial tells me you should be good for years!
