4 AIR PREPARATION PRODUCTS APP-124 For further information www.norgren.com * Approximate flow with 1000 psig (69 bar) inlet pressure, 60 psig (4 bar) set pressure and a 5 psig (0.35 bar) droop from set. † Outlet pressure can be adjusted to pressures in excess of, and less than, those specified. Do not use these units to control pressures outside of the specified ranges. R44 R83 Underwriters Laboratories, Inc. listed (file number SA1089) for use with air, argon, carbon dioxide, krypton, neon, nitrogen, xenon. For use with other gases, including oxygen, consult factory. Non-relieving and relieving models. Relieving models allow reduction of outlet pressure even when the system is dead-ended Ordering information Models listed have PTF threads, and relieving diaphragm.
