Re: [PSUBS-MAILIST] Hardregulatortank without pipeing

Hi Dave..

The hard-regulator-tanks are about 1,9 m (6 foot) long and
 have a diameter of 700 mm (27,6 inch) each for 700 liters 
( 185 galleon). Max.pressure is 50 ATM in the air pipes
 but different between inside and outside pressure should normal 
not greater than about 25 Atm.
