A-4000-1049 Johnson Controls Filter

Overview

The Johnson Controls A-4000-1049 is a high-performance coalescing oil removal filter designed to deliver clean, oil-free air for pneumatic control systems. Operating in series with an activated charcoal filter, this 3/8-inch NPT unit effectively eliminates both oil aerosols and vapors to protect downstream pneumatic equipment from contamination. It features an integrated automatic drain to automatically expel accumulated entrapped liquids and a differential pressure indicator to signal when the filter element requires maintenance.

Features

• Dual-stage purification removes both oil aerosols and vapors for comprehensive air treatment
• Automatic drain system automatically blows out entrapped liquid accumulations to maximize service life
• Integrated differential pressure indicator provides local visibility into filter status and maintenance needs
• Constructed with a durable plastic bowl suited for demanding mechanical equipment room environments
• Cost-saving design minimizes friction and supports higher airflow rates when integrated into pneumatic stations
