Re: Chinese high pressure compressors

I've done 2 top up fills from under 200Bar to a hair under 300Bar and one fill from empty per the set up described up to 300Bar using the new improved filtration set up. Excluding fuel, (going to and from the dive shop) I have saved at least £60 so far.

Re: Chinese high pressure compressors

Hi everyone, I have made an update to the filtration of this pump as I must admit, I have been a bit paranoid about any moisture or oil getting into my air arms rifle. So I drained my 4.5l tank upside down until empty, didn't notice anything that shouldn't have been there like any mist or vapour.......

Re: Chinese high pressure compressors

Well - as mentioned, my 4.5l bottle is less than a year old. It's rated for 300Bar (not sure what the tested saftey parameters are but I am guessing it's way above 300Bar.) I keep an eye on all the guages whilst the pump is working and I will not exceed 300Bar. There are folks I have read about who ...

Re: Chinese high pressure compressors

Still no sign of any customs duty or vat bill from FedEx....which is fine by me! Wanted to do another test as I took apart all the lines and did them back up again nice and snug with ptfe tape. I bled off the 4.5l tank to 200bar. Hooked it all up and fired up the pump. I timed it and it took 15 minu...

Re: Chinese high pressure compressors

Update: The pump arrived yesterday (6th Nov) pm, delivered by Fedex. I ordered the pump on the 24th Oct. I happened to have a day off from work today so that was lucky. Box was quite well taped up but it soon appeared that the polystrene inner packaging was buggered and there were fragments of tiny ...

Re: Carbon (or other) barrel shroud s4*0

Thanks guys for the idea - I went ahead and got a length of carbon fiber tubing - it was only £11 incl delivery and arrived after 2 days of ordering off of Ebay.

Looks bloody brilliant, with other folks at my local HFT wondering what type of S400 it is!
