A-4000-156 Johnson Controls Drain

Overview

The Johnson Controls A-4000-156 is a high-performance condensate filter assembly equipped with an automatic drain, specifically engineered for use with the A-4400 series refrigerated air dryers in pneumatic control systems. Designed to remove moisture, dirt, and fine particulate contamination, this device protects downstream pneumatic components like actuators, damper motors, and control valves from premature wear and clogging, thereby extending the overall life and reliability of commercial and industrial HVAC air preparation systems.

Features

• 5-Micron Filtration: Efficiently captures fine particulate and liquid condensate to ensure clean, oil-free air delivery.
• Automatic Drain Operation: Features a continuous, hands-free purge mechanism that automatically clears accumulated liquids from the filter bowl without interrupting system operation or dropping pressure.
• Comprehensive Assembly: Includes essential maintenance components such as a bowl o-ring (A-4000-610), drain valve (A4400-607), and filter element (A-4000-608).
• High Reliability: Built with durable materials for long-term operational consistency and reduced manual maintenance intervention.
