A-4000-6001 Johnson Controls Filter

Overview

The Johnson Controls A-4000-6001 is a high-performance coalescing pneumatic oil filter engineered for demanding air preparation applications in commercial and industrial HVAC control systems. It is designed to remove sub-micron aerosols, liquid oil mists, moisture, and fine particulates from compressed air streams, providing clean, oil-free air to safeguard downstream components. This model serves as a direct replacement for the older A-4000-601 filter assembly.

Features

• High-efficiency coalescing design that effectively captures and separates liquid aerosols and fine mists.
• Equipped with a built-in automatic drain mechanism to continuously discharge accumulated liquids without manual intervention.
• Features an integrated differential pressure indicator (DPI) to provide local visual tracking of filter restriction and maintenance needs.
• Constructed with a durable plastic polycarbonate bowl protected by a rugged bowl guard.
• Designed to support high-flow performance while maintaining a minimal pressure drop across the filter element.

Specifications

• Airflow Capacity: 40 SCFM nominal (supports up to 50 SCFM maximum)
• Connection Port Size: 3/8 inch NPT
• Filtration Efficiency: 99.999% for particles 0.025 microns and larger
• Maximum Operating Pressure: 150 psi (1,050 kPa)
• Maximum Operating Temperature: 125 degrees F (52 degrees C)
• Filter Type: Coalescing Oil Removal Filter

Applications

• Main line air preparation for pneumatic building automation and environmental control systems.
• Protection of highly sensitive downstream pneumatic controls, thermostats, actuators, and instrumentation from oil and water contamination.
• Industrial air supply filtration when used in series with activated carbon charcoal filters to remove both aerosols and oil vapors.
• Mechanical equipment room air compressor and pressure-reducing station configurations.
