Vacuum (absolute pressure less than 1 bar) can form in the filter's pressure tank when a pressure booster or reverse osmosis system is run downstream of the filter. This might cause it to implode. We advise using a BEV aeration and deaeration valve to prevent this. The valve for the outgoing product water line needs to be fitted on location. It needs to be installed at a higher location near the pressure tank.

Operating temperature 1 – 65 °C
Conditions of use If there is no aeration and dearation valve, the warranty will be void in the event of a vacuum causing the pressure tank to rupture.

Utilization OF Aeration and Dearation Valve For HSF/HEF/HAF Filters

  1. Fits filter series HSF, HEF, and HAF.
  2. Safeguarding a filter that runs upstream from a reverse osmosis system or pressure booster against negative pressure or pressure tank collapse.

Advantages OF Aeration and Dearation Valve For HSF/HEF/HAF Filters

  1. Adds additional security for pressure tanks.
  2. Simple installation.
