IHS Mikrovent

As low pressure hot water/chilled water enters the Mikrovent, the reduction in velocity caused by the Mikrovent's larger diameter ensures that any solid debris carried around the system precipitates out and can be removed periodically from its blow down point.
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 brushes ensures that any main system dissolved gases are removed by the lower brush, whilst gases entrained in the primary boiler 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.
