Installation Tips for Dirt and Air Separators

Even the best dirt and air separator will underperform if installed incorrectly. Following best-practice installation guidance ensures long-term efficiency and reliability.

 

Recommended Installation Location

For most systems:

  • Install on the flow pipe
  • As close to the boiler or heat source as possible
  • Before sensitive components (heat exchangers, pumps)

This placement improves separation efficiency by utilising higher temperatures and lower pressures.

Orientation and Positioning

  • Install vertically unless specified otherwise
  • Ensure air vents are positioned at the highest point
  • Allow sufficient clearance for servicing and magnet removal

 

Isolation and Servicing Access

Best practice installation includes:

  • Isolation valves above and below the unit
  • Drain points for debris removal
  • Easy access for routine cleaning

This reduces downtime and simplifies maintenance.

Installation for Heat Pumps

Heat pump systems require:

  • High-efficiency dirt separation
  • Continuous air removal
  • Minimal pressure loss
  • Minimal down time to ensure consistent flow

Choose separators designed specifically for low-temperature, high-flow applications.

 

Common Installation Errors

  • Installing on the return pipe unnecessarily
  • Insufficient servicing clearance
  • Incorrect orientation
  • No isolation valves
