Air Separator Afriso AAS 260 with automatic air vent and swivel female G1"A connection

Afriso AAS 260 is an air separator designed for heating and cooling systems that removes entrained air to improve hydraulic performance and system reliability. This model includes an automatic air vent for continuous degassing and a swivel female G1"A connection that allows flexible orientation during installation. The device is intended to reduce air-related circulation problems, decrease noise, and limit corrosion in closed circuit systems.

Advantages

The integrated automatic air vent continuously discharges trapped air without manual intervention, supporting stable operation and lower maintenance needs. The swivel female G1"A connection enables easier alignment with existing piping and simplifies installation in confined spaces. By facilitating air separation, the unit contributes to improved heat transfer efficiency and reduced risk of pump cavitation and flow disturbances.

Suitable for (tasks / use cases)

• Removal of entrained air from closed-loop heating systems (boilers, radiators)
• Degassing of chilled-water and cooling circuits
• Prevention of noise and flow irregularities in hydronic installations
• Applications requiring a compact air separator with built-in automatic vent

When it may not be suitable

This air separator is intended for closed heating and cooling systems and may not be appropriate for open systems or systems with aggressive fluids not compatible with the device materials. Systems with extremely high contaminant loads or heavy particulate matter may require additional filtration or dirt separators in front of the unit to avoid clogging or reduced performance.

Key specifications

• Function: air separation and automatic venting for hydronic systems
• Connection type: swivel female threaded connection G1"A for flexible installation
• Built-in feature: automatic air vent for continuous degassing
• Typical application: closed heating and cooling circuits
• Effect: reduces air-related noise, improves circulation and heat transfer

How to use

Install the Afriso AAS 260 on the system return or another suitable location where flow velocities promote air separation, observing correct pipe orientation and ensuring the swivel female G1"A connection is tightened and aligned for leak-free operation. After installation, the automatic vent will release trapped air continuously; periodic visual inspection is recommended to confirm vent function and to check for signs of leakage. If the system contains debris, fit a strainer or dirt separator upstream to protect the unit and maintain performance.

What to consider before purchase

• Confirm compatibility with system type (closed heating or cooling circuit)
• Verify pipe size and thread standard to match the swivel female G1"A connection
• Assess system fluid quality and consider pre-filtration if particulate matter is present
• Check available installation space for the device body and vent access

Usage recommendations

For best results, install the separator where flow encourages air collection (commonly on the return line near the heat source), combine it with appropriate filtration in dirty systems, and include routine checks of the automatic vent and connections as part of regular system maintenance.
