FEATURES<br />
Ingersoll Rand ARO Compact Series piggyback units are <strong>compact</strong> to save space, giving<br />
more design flexibility. The filter and regulator have a common inlet and a common outlet.<br />
This saves on space, set-up time, and piping costs.<br />
• Units have threaded ports for direct connection to pipe plumbing or, when used with<br />
modular port adapter kits, a single unit or combination of units can be piped into the air<br />
system in a modular arrangement.<br />
• Push / pull, non-rising knob allows one-hand adjustment. Pull to adjust, push to lock.<br />
Arrows on the knob indicate pressure increase and decrease.<br />
• Balanced valve-type diaphragm regulation assures positive pressure adjustment and<br />
rapid response to inlet pressure changes.<br />
• Regulator offers in-line repairability. Valve and diaphragm can be replaced without<br />
removing unit from line.<br />
• Bayonet bowl attachment provides easy filter element removal.<br />
• Inlet / outlet is stamped into housing for easy air line hookup.<br />
• Automatic drain has 1/8" NPT connection for draining away contaminants.<br />
• 10 psig minimum operating pressure.<br />
NOTE: See cautions on the use of polycarbonate bowls.<br />
DIMENSIONAL DATA<br />
Dimensions – in (mm)<br />
Relieving with manual drain<br />
CAUTION: Outlet pressure adjustment ranges are not minimum or maximum outlet pressure limits. Regulators can<br />
be adjusted to zero psig secondary pressure and, generally, to pressures in excess of those specified.<br />
The use of these regulators to control pressures outside of the specified ranges is not recommended.
