Overview

The Midwest Control MCWB18B-50A compressed air filter regulator combines particulate filtration and pressure regulation into a single air preparation unit for pneumatic systems. The integrated filter helps separate dust, dirt, moisture, and other contaminants from compressed air lines while the regulator maintains steady outlet pressure despite inlet pressure fluctuations.

This unit features an aluminum body construction with a quick disconnect aluminum bowl and a 5 micron filter element designed for compressed air system maintenance and protection. The regulator section uses a balanced valve design with a spring-loaded diaphragm for stable pressure control performance.

The MCWB18B-50A is suitable for industrial compressed air systems, pneumatic equipment, air tools, automation systems, and general shop air preparation applications.
