Honeywell 1991-0147 End-of-Line Particulate Filter for Pneumatic Systems

The Honeywell 1991-0147 is an end-of-line particulate filter designed to protect pneumatic instruments, sensors, and control devices from airborne contaminants at the terminal point of a compressed air or gas distribution system. Installed at the point of use, it serves as a final line of defense against dust, pipe scale, rust particles, and other debris that can degrade performance or damage downstream equipment.

Key Features:

• End-of-line design provides point-of-use filtration at the termination of a pneumatic line
• Removes particulate contamination from compressed air or instrument gas supply
• Protects sensitive pneumatic instruments, actuators, and control valves from fouling
• Compact form factor suitable for panel or inline installation
• Manufactured by Honeywell, a trusted name in industrial sensing and process control

The 1991-0147 is commonly used in industrial process control environments where clean, dry instrument air is critical to the reliable operation of pneumatic transmitters, positioners, and regulators. It is a Honeywell genuine replacement or accessory component, ensuring compatibility and performance standards consistent with Honeywell instrumentation systems.
