The AIRMIXS AR4000-04 High-Precision Air Pressure Regulator is a heavy-duty, high-flow air control unit designed for demanding industrial pneumatic distribution systems. Featuring a standard G 1/2" port size and a balanced valve design, this regulator minimizes pressure offset and stabilizes downstream airflow to ensure connected actuators, machinery, and air tools operate at steady performance levels.
Constructed with a rugged die-cast aluminum housing, it provides exceptional physical durability in challenging production environments. The ergonomic top-adjustment knob includes a push-to-lock detent mechanism—pull up to set the exact pressure, then press down to lock it in place to protect against setting changes caused by machine vibration. Outfitted with a back-mounted pressure gauge and a heavy-duty mounting bracket, it is ready for standalone or modular installation.
