Wilkerson ER1-04-0000 Electronic Air Regulator 150 Psi

Product Description

The WILKERSON ER1-04-0000 is an electronic compressed air regulator designed for precise, signal-driven pressure control in pneumatic systems. Operating on a 0 to 10 VDC control signal, it delivers regulated output from 0 to 125 psi against a maximum supply pressure of 150 psi. With a maximum airflow capacity of 200 CFM and a 1/2 inch NPT port, this unit suits high-demand automation and process control applications. The aluminum body keeps weight low at 1.76 pounds. A built-in relief function allows downstream pressure to vent when the setpoint is reduced, protecting connected equipment and maintaining accurate control.

The ER1-04-0000 is suited for industrial and commercial pneumatic systems where analog electronic control of air pressure is required. Typical applications include automated machinery, process lines, and control panels where a PLC or analog output card drives pressure setpoint via a 0 to 10 VDC signal. The modular connection feature allows this regulator to be banked with other Series ER1 components for manifold-style installations. Fluid type is compressed air only. Minimum operating temperature is 32 degrees F. Installation is typically performed by industrial maintenance technicians, instrumentation techs, or licensed pipefitters.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician, instrumentation specialist, or licensed pipefitter. Isolate and depressurize the air supply before servicing any pneumatic component. Ensure the analog control signal source is powered down before wiring the 0 to 10 VDC control input. Follow all applicable codes and the equipment manufacturer guidelines for pneumatic system installation and control wiring.
