        Energysaver™ Dryair Compact Positive Pressure System
a
 

Our Energysaver™ Dryair positive pressure systems are simple to install and inexpensive to run. Two versions are available; one for loft installation and one for flats. Both come with preheat options.

Fresh, dry, filtered air at ambient temperature is introduced continuously into the property - diluting and displacing stale, moist air and reducing condensation.

The Dryair Compact is also beneficial in repelling the natural seepage of radon in those parts of the country where levels are thought to be a problem.

Design includes a digital motor with a pressure sensor that triggers an LED alert should the filter become blocked. An innovative ‘Feedback’control ensures the system continues to operate at 100% efficiency until the filter becomes 70% clogged.

a Construction
Housings are rotational moulded, flame retardant plastic with a lifetime warranty.

Filters
Loft Model: Non woven type processed to labyrinth structure ensuring good air distribution. The synthetic fibres are resistant to moisture, fungi, bacteria and frost. Model VNF250. Heat resistance <100ºC. Flammability – self extinguishing to DIN 53438 F1
Flat Model: Totally open reticulated foam post, treated to improve flame retardant properties

Installation
A loft unit is fitted in the roof void and ducted via an air diffuser, normally mounted in the ceiling above a stairwell. For units fitted with pre heat facility, the heater control switch is sited on the landing wall at a convenient height to enable the user to switch the heater on or off. Also, the fan speed control is set from this position.

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 hall 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.		 a a
