4500PSI/30Mpa PCP Compressor Mini Double Cylinder for Scuba Tank | 110V air compressor, lightweight portable, works for paintball guns & scuba diving tank filling, manual shut-off design

great unit

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!

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

Dysfunctional

Impressed so far

Item arrived and filled with oil and turned it over several times but as soon as it was plugged it it blew a 13 amp fuse. I tried a choke but the fuse just blew. This is the second item from this seller. The last item worked once and then just stopped. I think Iwould look elsewhere for a more reliable item

Product delivery very good 👍

Works really well, used it quite a few times now it's very efficient at what it does, saves all that hand pumping.The only thing it needs is good set of instructions, apart from that it is a solid machine and does the job.Thank You Dave.

Rubbish item, just kept blowing the electric. Never worked, maybe check before shipping.
