Re: [PSUBS-MAILIST] Breathable air compressor

[Øystein Skarholm <skarholm@gmail.com>]

The Hookah utilize a low pressure compressor and the scuba refill compressors are High pressure. It will be like comparing aple and banana.

The filters deals with the vapour. It is also special oil to be used in the brating air compressors. To build a compressor is not cheaper then to buy one unless you know your way around cheap parts.

Hi guys, I’m fairly interested in SCUBA… as well as being VERY interested in subs… ive got a fairly good understanding of air compressor types etc… but does anyone here have any knowledge on the principal workings of a hookah or scuba tank filling type compressor? Its just something that ive never quite understood, and ive seen scuba refill compressors cost upwards of $2500AUD.. so I thought why not make one! J

 

One of the pre-requisites is an oil-less lubrication system for the piston/vanes? Obviously oil vapour in the breathing air isn’t a good thing J

 

Anything else anyone can put forward to further my knowledge?

TIA  Stew
