## Summary description

Afriso FAR 311 is an air separator for hydronic heating and cooling systems, equipped with an automatic air vent to remove entrained air. It features Rp3/4" connections and is intended to improve system efficiency, reduce noise and corrosion, and maintain stable circulation in radiators, boilers and heat exchangers.

## Long description

Afriso FAR 311 is an air separator designed for hydronic heating and cooling systems. The unit integrates an automatic air vent and Rp3/4" threaded connections to remove entrained air from circulating water. Installed in supply or return lines, the separator helps reduce noise, improve heat transfer efficiency and minimise corrosion by preventing air pockets in radiators, boilers and heat exchangers.
Advantages
The FAR 311 combines a compact body with an internal flow path that promotes separation of microbubbles and larger air pockets. The built-in automatic air vent continuously discharges collected air without manual intervention. The Rp3/4" connections provide compatibility with common residential and light-commercial piping, and the device is constructed for reliable operation in typical hydronic circuit conditions.
Suitable for
Residential and small commercial hydronic heating systems
Central heating circuits with radiators and convectors
Boiler and heat exchanger feed and return lines
Hydronic cooling systems where trapped air affects performance
When it may not be suitable
The FAR 311 is intended for typical heating and cooling circuits and may not be appropriate for very large industrial systems or process plants that require higher flow capacities or specialised materials. Systems with unusually high concentrations of dirt or particulate matter may reduce separator effectiveness unless adequate filtration is installed upstream.
Key specifications
Connection type: threaded Rp3/4"
Function: air separation with automatic venting
Application: hydronic heating and cooling circuits
Installation position: inline on supply or return pipework
How to use
Install the Afriso FAR 311 in the pipework where flow velocity allows air to rise into the separator chamber, typically on the return line near the boiler or heat source. Ensure the unit is mounted upright and the automatic vent is accessible. After installation, bleed the system according to standard commissioning procedures then monitor the vent; the device will continuously remove entrained air during operation. Periodic visual inspection and routine system maintenance are recommended to ensure long-term performance.
What to consider before purchase
Verify pipe thread compatibility with existing Rp3/4" connections
Confirm flow rates and system size are within typical domestic or light-commercial ranges
Check that upstream filtration is present if the system contains particulates
Ensure sufficient space and upright mounting position near the boiler or heat exchanger
Usage recommendations
For optimal performance, install the separator on the return side near the heat source, keep the automatic vent accessible for inspection, and combine the FAR 311 with a suitable strainer or filter when particulate contamination is expected.
