The Johnson Controls A-4000-1037 In-Line Pneumatic Filter Barb is a compact filtration component designed to protect pneumatic HVAC control systems from dust, oil, and debris. Installed directly in pneumatic tubing, the in-line barb filter allows compressed air to pass through while trapping contaminants that could damage sensitive control devices. It is commonly used with pneumatic thermostats, actuators, dampers, and air control valves in building automation systems. By maintaining clean airflow, it improves control accuracy, extends equipment life, reduces maintenance issues, and supports reliable operation of pneumatic HVAC control networks.
For an efficient and reliable HVAC system, the Johnson Controls In-Line Pneumatic Filter Barb is a great choice for optimal system performance.
