Armstrong International C5534 Air Vent

The Armstrong International C5534 Air Vent is a high-performance Series 1AVC See-Thru Air Vent engineered for the continuous removal of air and non-condensable gases from hot water systems and specialized steam applications. Featuring a 1/2" NPT connection and a 1/8" orifice, this industrial air vent utilizes a transparent polysulfone body, allowing for immediate visual inspection of operation without system downtime. Designed to withstand a maximum operating pressure of 150 PSI, the C5534 ensures your HVACR system maintains peak thermal efficiency by preventing air-related corrosion and heat transfer resistance. The assembly integrates a stainless steel float and lever mechanism with a zinc-plated steel retainer ring for enhanced chemical resistance. Whether used in hydronic heating or industrial liquid lines, this automatic air vent provides a durable solution for maintaining a gas-free environment in critical piping networks.

Key Benefits of the Armstrong C5534

• Enhanced System Efficiency: Effectively eliminates air pockets that cause pump cavitation and reduced heat transfer.
• See-Thru Visual Monitoring: The polysulfone body allows technicians to verify float movement and fluid levels instantly.
• Superior Corrosion Resistance: Equipped with stainless steel internals and a reinforced nylon plug to prevent degradation in harsh environments.
• High-Pressure Versatility: Rated for up to 150 PSI, making it suitable for both commercial and industrial liquid services.
• Compact Installation: The 1/2" NPT inlet/outlet design fits seamlessly into standard piping manifolds.

Common Questions About Air Vents

How do I know if my air vent is malfunctioning?
If the system becomes noisy or you notice a decrease in heating efficiency, check the transparent body of the Armstrong C5534. If the float is stuck or fluid is leaking from the vent orifice, the unit may require cleaning or replacement.

Can this vent be used in high-temperature water applications?
Yes, the Series 1AVC is specifically designed for hot water systems. The polysulfone and stainless steel construction are selected for their ability to handle elevated temperatures and pressures up to 150 PSI.

Where should the Armstrong C5534 be installed in a piping system?
For maximum AEO performance, install the vent at the highest points of the system or immediately after air separators where gases naturally accumulate.
