Allegro's Multi-Regulator Air Filtration Panels are the industry standard in multi-worker air purification. The 3-stage filtration system removes harmful contaminants to keep your workers safe! These MR units' unique design allow each regulator to be adjusted individually at different pressure settings, allowing separate outlets for air tools. Built in monitoring window allows viewing of pressure gauges. A 16 gauge steel stand is included for support as well as brass plumbing and quick-disconnect Hansen couplers. All models meet NIOSH requirements for point-of-attachment.
