Air vent FLEXVENT TOP 28515, female thread 1/2 inch, without check valve, operating temperature up to 120°C, pressure up to 10 bar, glycol concentration up to 50%

Automatic air vent for heating and air conditioning systems

This automatic float air vent, known as FLEXVENT TOP, is a reliable solution for removing air from heating and air conditioning systems. Its design based on the float principle ensures effective and maintenance-free removal of accumulated air, which translates to optimal system performance. This model is particularly recommended for commercial applications where high performance and reliability are required.

Construction and application

The FLEXVENT TOP air vent is characterized by a solid brass construction, which guarantees its durability and corrosion resistance. It has a cylindrical BSPT-Rp internal thread with a diameter of 1/2 inch, which allows for easy installation in standard installations. The lack of a check valve makes it ideal for mounting at the highest point of the installation, where air naturally accumulates. Using this air vent allows maintaining optimal pressure in the system and prevents problems related to the presence of air, such as noise, reduced efficiency or corrosion. It is adapted to work with glycol with a concentration of up to 50%, which makes it suitable for installations with antifreeze fluid.

Key features and benefits

• High efficiency: Float design ensures effective removal of air from the system.
• Durability: Made of brass, resistant to corrosion and mechanical damage.
• Wide range of temperatures and pressures: Adapted to work at a temperature of up to 120°C and a pressure of up to 10 bar.
• Glycol compatibility: Can be used in installations with antifreeze fluid with a concentration of up to 50%.
• Easy installation: 1/2 inch internal thread facilitates integration with the existing installation.
• No check valve: Allows mounting at the highest point of the installation for maximum efficiency.
• Leak protection: The design ensures tightness and minimizes the risk of leaks.
• With air inlet barrier: Additional protection against dirt and contaminants entering the device.

The FLEXVENT TOP air vent is an investment in trouble-free operation of the heating or air conditioning system – both for professionals involved in installation and for end users who value comfort and reliability.
