"Hi Frank

Thanks for your inquiry.

The size and price of the membrane depends on the amount and 02 % of nitrox
you will need to pump and on your existing equipment. Membranes must be
matched in size to the compressor that will be used and both determine the
pumping rate. Also membranes must have feed air at a ration of 2 to 1 for
nitrox produced. Compressed air is "fed" into the membrane where nitrogen
is separated and the resultant nitrox pumped by high pressure compressor
into bottles or storage. This feed air can be stored air or bottles or from
a low pressure compressor.

So to give you a proper estimate we need to know the model and manufacturer
of your high pressure compressor, the amount of hp storage you have, if any.
Also if the system will be used on land or on a boat. After we receive the
above information we'll get back in touch with prices. Basically, however,
our smallest 8cfm membrane systems are $8250.00, the 16cfm system is
$12,950.00 and they go up in size and price from there. That price includes
everything you need to start pumping nitrox except the compressor. See the
attached files (brochures) for the details. Boat installation are a little
different of course because of space issues, type of gen set, etc.

Our web site at will give you access to configuration drawings
and additional system information.

If you need more information please feel free to contact us - you can call
