Johnson Controls T-4000-622 Aspirater Filter

The Johnson Controls T-4000-622 Aspirator Filter is a critical replacement component for maintaining high-performance pneumatic control systems. Engineered specifically for the T-4000 Series Pneumatic Room Thermostats, this kit ensures clean air and gas flow by effectively removing airborne contaminants that can leading to abrasion or mechanical failure in sensitive temperature control elements. This comprehensive HVAC filter kit includes a high-grade aspirator elbow, resistor, and 1/8-inch O.D. polytubing with filter, providing a complete solution for field repairs and routine maintenance. Built for industrial-grade durability, it operates reliably across a broad temperature range of -4?F to 122?F, making it suitable for demanding commercial HVAC environments. By preventing dust and debris from fouling pneumatic thermostat orifices, the T-4000-622 maintains calibration accuracy and optimizes overall system efficiency. Proper filtration is essential for the longevity of your HVAC control equipment, ensuring that air sampling for thermostats remains precise and unobstructed under standard operating pressures.

• Critical Component Protection: Purifies air streams to protect sensitive internal bellows and orifices from debris-related damage.
• Precision Sampling: Facilitates accurate room air sampling when used in concealed mounting or aspirator wallbox configurations.
• Complete Installation Kit: Includes the aspirator elbow, resistor, and 1/8" O.D. polytubing for a seamless field replacement.
• Industrial Resilience: Specifically rated for performance in environments ranging from -4?F up to 122?F.
• OEM Compatibility: Guaranteed fit and function for Johnson Controls T-4000 Series devices used in complex pneumatic loops.

• What thermostats is this filter compatible with? It is designed specifically for the Johnson Controls T-4000 Series, including single and dual temperature models requiring an aspirating feature.
• Why is an aspirator filter necessary in pneumatic systems? Pneumatic controls rely on small orifices that are easily clogged; this filter prevents contaminants from entering the control head through the sampling air.
• How often should the T-4000-622 be replaced? It should be inspected during seasonal PMs and replaced if discoloration or restricted airflow is observed to maintain thermostat sensitivity.
