Armstrong International A5345 Thermostatic Air Vent

The Armstrong International A5345 Thermostatic Air Vent is a precision-engineered replacement component designed specifically for Series B Float and Thermostatic Steam Traps. Built to withstand the rigorous demands of industrial steam systems, this thermostatic element ensures rapid discharge of air and non-condensable gases during startup and continuous operation. By facilitating efficient air venting, the A5345 prevents steam trap air binding and improves overall heat transfer across the system. This balanced pressure thermostatic air vent features a robust bellows design capable of handling high-velocity discharge without premature fatigue. It is essential for maintaining the operational integrity of Armstrong F&T steam traps, ensuring that condensate drainage remains uninterrupted. Integrating the Armstrong A5345 replacement kit into your preventative maintenance schedule reduces the risk of water hammer and thermal shock within the heat exchanger. This component is optimized for HVAC steam system maintenance and industrial process steam applications where reliable air removal is critical for efficiency.

• Ensures rapid automatic air venting for faster system start-up times.
• Hardened stainless steel construction for superior resistance to corrosion and water hammer.
• Direct Armstrong B Series repair part compatibility ensures a precise fit without field modifications.
• Improves energy efficiency by eliminating air-insulating films on heat transfer surfaces.
• High-capacity discharge design prevents air binding in industrial steam traps.

How do I know if my Armstrong A5345 thermostatic air vent has failed?
Failure is typically indicated by a cold steam trap despite pressurized steam in the line (air binding) or if the trap is blowing live steam through the vent port due to a ruptured bellows.

Is the A5345 compatible with all Armstrong F&T traps?
The A5345 is specifically engineered for the Armstrong B Series Float and Thermostatic traps. Consult the trap nameplate to verify the series before installation.

Can this vent be serviced without removing the trap from the piping?
Yes, once the steam supply is isolated and the trap has cooled, the cap can be removed to replace the A5345 element directly in-line.
