Prudent dive shops strive to maintain a low dew point in their scuba air and also achieve maximum life expectancy from expensive filter cartridges. However, air must be 99% dry before entering the chemical filters or neither objective will be met! To accomplish this, an after-separator and a priority valve are required. The latter unit is an adjustable check valve which holds about 1700 psi of back-pressure on the filter system at all times. This raises the density of the air, increases the efficiency of the separator (100% or more), and thereby lengthens the life of the filter chemicals. The process is called pressure-drying. Preset at about 1700 psi. One inlet, 2 outlets - 1/4 NPTF. 6,000 psi rating. Rebuild Kit #46151.
Working Pressure: 6,000 psi.
Inlet Port: 1/4 NPT female.
Outlet ports (2): 1/4 NPT female.
