Standard features include a relieving regulator, which can be quickly locked by pushing down on the adjustment knob. There are many options, which include gauges, auto-drain, metal bowl and covers, different set pressures, etc. The AW is part of the family of modular air preparation units and can be combined with other similar sized products.
IR1000-A, IR2000-A, and IR3000-A series precision regulators as well as IR1200-A, IR2200-A, and IR3200-A series regulators were released in August 2014. 
The ARP is a modular style, direct operated precision regulator. A locking adjustment knob allows the pressure to be set, and then locked to prevent accidental setting changes. The ARP20/30/40 series is available with a back flow function that exhausts the air pressure in the outlet side reliably and quickly.
