Automatic air vent, vertical PrimoVent G 3/8 inch with Aquastop and check valve R 1/2 inch 7773510

Automatic air venting and heating system protection

This vertical PrimoVent automatic air vent from AFRISO is a reliable solution for removing air from closed heating systems in accordance with PN-EN 12828. Its design allows for effective operation both during normal operation of the installation and during its draining, where it functions as an air release valve. This ensures optimal performance and trouble-free operation of the system.

Key features and benefits

• Aquastop system: Protects against water leakage in case of damage or contamination of the valve, minimizing the risk of flooding. It works by increasing the volume of seals in contact with water, shutting off the air supply.
• R1/2 inch bottom valve: Allows easy removal of the air vent without the need to drain the entire installation – this facilitates maintenance and device replacement.
• Durable construction: Made of brass, which guarantees corrosion resistance and long-term use.
• Versatility: Can be used with water and water-glycol mixtures (up to 50% concentration), making it compatible with various types of heating systems.
• Automatic operation: Eliminates the need for manual venting, providing continuous protection against air entrapment and its negative effects – such as noise, reduced efficiency or corrosion.
• Vertical mounting: Ensures correct operation of the device – mounting in the highest points of the installation guarantees effective removal of accumulated air.

Application and compatibility

The PrimoVent air vent is ideal for use in:

• Central heating (CH) installations
• Refrigeration systems
• Heating boiler installations
• Wall and ceiling radiators
• Expansion vessels

Thanks to its operating parameters (maximum temperature 110°C, maximum pressure 12 bar), this air vent will work in most standard heating installations. The bottom valve with a GZ 1/2 inch connection facilitates integration with the existing piping system.
