PPF9 Positive Pressure System.

PPF9 Positive Pressure UnitOne approach to the treatment of widespread condensation in a property is to use a 'positive pressure system.' This consists of a slow speed fan set into the ceiling. It draws air into the roof space from the outside through the eaves, and gently pushes it into the property. This causes a slight internal positive pressure, continually pushing out any moisture-laden air. Safeguard supply the the PPF9 Positive Pressure system which has the following benefits:

  • 3 pre-set speed settings
  • Robust construction
  • Long-life filter
  • Low noise levels
  • Low running costs
  • Protected with thermal cut-out
  • BRE Digest 398 compliant
  • 5 year guarantee

This type of system can also be used to dilute levels of radon in existing dwellings as part of a radon reduction strategy.
