Scuba Tank Compressor, 4500psi PCP Air Compressor, High Pressure Air Compressor, Double Cylinder PCP Diving Pump for Paintball Scuba Tank 110V (TXEDM041)

Really good and silenced

I purchased the two head HP compressor from Tuxing to fill my Pony SCUBA tanks for short dives. The compressor works at filling my 2L Pony tanks. This is an update on this compressor. The compressor worked to fill two small air tanks. I didn’t go over 2,500 psi. The compressor was rated at 3,500 psi. On my third small 2L tank the pressure got up to 1,500 and stopped increasing in psi. I found a leak in the pressure release value and fixed the leak. I tried again to fill the tank, but the psi kept dropping. I did a bubble test and found bubbles by the cylinder head gasket. And a small blowout piece of gasket! See jpg. I asked for help from the company Tuxing! I could do the repair myself if they would send a pdf of a repair manual with a schematic and torque values for the cylinder head nuts, and gasket information. But, I have received the run around, and they sent attachments that could not be opened! What did I download? I had given them previously an excellent review! But, the support from the manufacturer & seller isn’t working. I am attempting repairs blindfolded without a proper manual. The Tuxing small slip of paper they call a manual is useless!

Quit working the 2nd time i used it. Could't get a replacement took forever to get a refund. Looks like a good ides BUT because of poor asslembly IT"S NOT. Too bad they dont have 0 stars

Won't reach 4500 psi ! Highest pressure I could get out of it is around 280 BAR far from the advertised 4500 psi.

Dysfunctional

Doesn’t build pressure for first time use. To late to return since more then 3 months. Did break in procedure and will only build 1000psi

I was considering this compressor, but I find there is far too little technical info available on Amazon to make a decision to purchase it. For example there are no electrical specs. regarding the elec. service capacity necessary to operate the compressor. There is no indication as to how long it would take to fill an 80 cu.ft. dive tank - my primary need. Additionally, no information on global service centers. How often to change filters/number of scuba tanks filled.
