Mikrofill Low Loss Headers

Mikrovent 250

Low Loss Header

The Mikrovent 250 is a Low Loss Header and Air & Dirt Separator suitable for connected loads of up to 250 kW.


As water impinges on the spiral wound brushes a low pressure area is created behind each filament of the brush, this forces any dissolved gases to be released.

The use of two removable stainless steel brushes ensures that any dissolved gases within the system are removed by the lower brush, whilst gases entrained in the boiler header system are released by the upper brush.

These gases then rise to the top of the unit and are expelled by the automatic air vent.

Mikrovent headers are available to suit connected loads of 150, 250, 400, 750 and 1000 kW.

All in all the Mikrovent is a worthwhile addition to any new or refurbished commercial heating or chilled water system.
