I just received my Yong Heng Compressor from ebay for $282 shipped from a warehouse in California. Best price I could find before the holidays.
Mine is the 110V version and came well packaged and fast via FedEx. No visible damage to inside or outside the box.
Some initial impressions:
1. Instruction manual states to install hose at the air outlet and "Note: gasket is needed, or air leakage might exist."
I tried this with a supplied O-ring and all that happened is it caused the pressure to rise very rapidly (NOT OK) up to above 3K PSI and climbing, which had me quickly open the bleed valve in a panic and troubleshoot the problem.
I realized that the O-ring was blocking the air outlet and was not needed to create a good seal between the threaded hose adapter and the delrin seal inside the air outlet.
Solution: Just use the supplied delrin seal and tighten up the connection with a wrench to prevent leaks. Mine has not had any leaks. You could use some plumbers thread tape if needed.
2. Make sure your AC outlet can handle the load of the unit. For some reason, plugging the unit in my GFCI outlet would cause the unit to hesitate to start, requiring to restart the unit a few seconds later. This issue stopped when I plugged it into a regular outlet along the same wall in the same room - don't know if the GFCI outlet may be the issue but just FYI. My compressor will work fine attached to a small extension cord with no hesitation on startup.
3. The supplied female foster end may not attach to some rifles directly - Example: I have a Daystate Huntsman Regal XL with the male foster fitting just under the barrel, and the supplied hose with the wide filter end won't fit under the barrel. You may need to purchase an extension hose in that situation.
4. I plug my guns up directly to the compressor since I don't own any CF tanks. I was able to fill my Brocock Compatto rifle from zero to 200 bar/3K PSI in roughly 1 minute of run-time.
5. I purchased and am using O'reilly Auto Parts AW46 Hydraulic Oil with no issues. Bought a gallon for $14. No overheating.
6. Make sure your water pump flow lever is set to (+) side to allow for maximal water flow.
7. Avoid the water lines from coming into contact with the exposed external air lines which heat up and can potentially cause damage to the water hoses. I just used a twist tie to keep both hoses together and away from the exposed metal air lines.
