Shipping weight ( lbs.):

Operating temperature range:
-20° F - 120° F
Supply pressure range:
* 5 - 120 psi max.
Supply requirements:
Clean air or inert gas
Safe pressure (CI/CII):
0.25" / 1.0"
Safe pressure flowrate:
** 0.1-3.5 SCFH
System supply fitting:
1/4" tube fitting
Enclosure supply fitting:
1/4" tube fitting
Enclosure reference fitting:
1/4" tube fitting
* With enclosure protection vent - 120 psi maximum
Without enclosure protection ven - 5 psi maximum
In order to comply with the NFPA 496 standard requiring
protection against over pressurization of the protected
enclosure, the installer must install one of the following items
in addition to the enclosure protection system.
a) Install an enclosure protection venon the protected
enclosure.
b) Install a tamperproof regulator upstream of the enclosure
protection system's system supply inlet to pre-regulate
protective gas supply to 5 psi max.
In addition, for small, tightly sealed enclosures, or to
compensate for a fluctuating protective gas supply, it may
be necessary to pre-regulate the protective gas supply to a
constant 5 psi regardless of whether an enclosure protection
ven is installed. This will reduce the amount of "drifting"
that can normally occur when maintaining a "Safe" pressure
inside a protected enclosure. The pre-regulation can be
accomplished by installing a TR-10G tamperproof regulator
accessories or equivalent.
** Enclosure integrity determines actual flow rate
