AutoPurge 2
No electrical required
Purges FPS piping to ensure entire system is blanketed with 98%+ nitrogen purity
Patented, calibrated orifice custom tunes to each individual riser based on its total capacity (gallons), minimizing runtime of N2Blast

One AutoPurge is required per dry or pre-action system
AutoPurge Timer
Manual reset to resume purging when the FPS is tested or trips
Purge automatically turns to the “closed” position after 5 weeks (field adjustable)
Eliminates the continuous venting of the AutoPurge System/s by closing the purge after 98%+ nitrogen (i.e., the desired purity level to inhibit corrosion) has had sufficient time to cycle throughout the FPS

South-Tek’s Regular Air Maintenance Device (RAMD) is a pressure regulating device that will keep nitrogen or air pressure at the correct level in dry pipe and prepare-action fire sprinkler systems. RAMD is used in conjunction with sprinkler systems with automatically controlled compressed nitrogen at a pressure higher than required for proper system operation. The RAMD includes a manual bypass that, after sprinkler system maintenance or operation, allows quick filling of the sprinkler system.
