CA1 Automatic Air Vent - Automatic Air Vent

Automatic air vent designed to automatically release unwanted air and microbubbles from closed-loop heating and cooling systems. It helps reduce system noise, prevent airlocks, and maintain efficient circulation. Its vertical design allows it to be installed at the highest points where air tends to accumulate. The unit is constructed from nickel-coated brass, features a float-controlled vent mechanism, and operates without requiring external power or regular servicing.

Features and benefits:

• Float-controlled automatic air release mechanism.
• Vertical installation only – ensures air separation performance.
• Nickel-plated brass body for long-term durability and corrosion resistance.
• Suitable for water and water/ glycol mixtures (up to 50% glycol).
• Robust polypropylene float designed for long service life.
• The design includes a ½” BSP male connection with a slight installation gradient (2° max).
• No electrical or manual intervention is required during operation.
• Supplied with a removable ½” cap to allow system pressure testing during commissioning.
