Flexvent 3/4

The compact, proven design has high efficiency and guaranteed operation for heating and air conditioning. The water within the installation contains air which can form corrosion and reduce the thermal transfer. A Flexvent is fitted at places where the air collects. Float operated, the air is collected in the Flexvent causing the float to drop and open the air release valve. The water pressure then pushes the air out, the float rises and closes the valve. The air cushion in the upper part of each Flexvent protects the valve seat against contamination. Technical Specifications: • Minimum/Maximum working temperature: -10 °C / 90 °C (peak load: 120 °C). • Minimum/Maximum working pressure: 0.2 / 10.0 bar (functional: 6.0 bar). • Suitable for addition of glycol-based anti-freeze up to 50%.
