The ARP is a modular style, direct operated precision regulator.&nbsp; A locking adjustment knob allows&nbsp;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.&nbsp; Special applications include (10-) clean room compliant, (20-)copper-free, fluorine-free, and (21-) clean room compliant, copper-free, fluorine-free and silicon-free.</p><ul><li>Direct operated precision regulator</li><li>Sensitivity: within 0.2%F.S.</li><li>3 types of set pressure allow more freedom in designing a circuit</li><li>Repeatability: within <span style="FONT-SIZE: 10pt">?1%F.S.</span></li><li><span style="FONT-SIZE: 10pt">Backflow function available</span></li></ul><br><p></p>
