EnergySaver Dri Air Systems

Envirowise EnergySaver DriAir Systems (Positive Pressure Units)

The EnergySaver DriAir System from Envirowise is designed to provide a reliable solution to condensation and air quality problems within the home. Two versions of the positive pressure system are available – one for use in lofts in houses and the other designed for flats and apartments.

The systems works by introducing fresh, dry, filtered ambient air into the property. This ‘clean’ air is circulated around the property diluting and displacing the stale moist air and ultimately reducing the humidity levels to control condensation. The pictures below show the two versions – the loft version on the left and the flats and apartments model on the right.

The positive pressure systems are also proved to be beneficial in repelling the natural seepage of Radon Gas in areas where Radon levels are a danger.

Envirowise EnergySaver Positive Pressure Ventilation System features:

  • Five year guarantee
  • Helps lower energy costs
  • Controls condensation and mould growth within the property
  • Reduces the build up of Radon Gas where this is a problem
  • Low maintenance

Our EnergySaver Positive Pressure Loft System also features:

  • A new state of the art digital motor – The positive pressure unit will constantly measure the airflow and keep the airflow at the desired rate. This new motor is also more efficient than our previous motor.
  • A new LED light on the heat switch panel – A clear indicator to show when the filter needs changing.
  • New style filter cover – Our new filter is now the largest available for a positive pressure loft unit giving clients an increased working life of the filter. Air is also now filtered from all sides of the unit.
    As can be seen from the picture to the left the new unit can now be hung directly from a rafter or a cross member. This allows a less intrusive installation than the traditional unit which was fitted directly on to ceiling joists. An added benefit is also less vibration and noise when in use.

How the positive pressure units work

The loft unit is fitted into the roof void and ducted via an air diffuser, normally mounted in the ceiling above a stairwell. Where there is a pre heat facility a control switch is conveniently sited to allow the user to control the heat facility and the fan speed.

The flat unit is fitted on a convenient wall, as close to the intake point as possible, Ideally the unit should be fitted inside a half cupboard, where access to an external wall and ambient air is possible. Supply ducting is then run to an outlet air grille, normally situated in the hall, in order that the introduced air is delivered to a central point within the dwelling.
