The units is designed for continuous operation providing up to 70% heat recovery, effectively

controlling internal relative humidity. The integral high efficiency pollen filter helps eradicate house

dust mites to improve health and indoor air quality. Fresh pre-warmed air from the outside

is continuously provided to the room with simultaneous extraction of stale, moist air.

n An integral heat exchanger transfers heat from the outgoing stale air to the fresh air supply raising

the temperature of the fresh air and most importantly reducing the relative humidity of the supply air.

n This provides control of condensation and odours and creates conditions which can eliminate

house dust mites.

n Efficiency: the unit should retain up to 70% of the temperature differential of out going air.

n Heat exchanger: should be of a multi plate cross-flow type constructed out of a polymeric plastic

with ultra sonic welded joints.

n Motor: should be a 2speed 240V 50/60Hz A/C with sleeve bearings, greased for life. It shall operate

up to an ambient temperature of 40oC and be fitted with a one shot thermal overload protective device.

n Fan: The two polymeric fan impellers should be a centrifugal forward curved type, dynamically

balanced mounted on a common shaft.

n Controls: The unit should be operated via a remote Trickle Boost Switch or via various automatic

sensors. A light switch can be used providing a ‘timed out’ device is employed. Filter: should be

a reticulated foam type coarse filter on the extract air and a EU2 pollen filter on the supply air.

Condensation: The outlet should be via drain holes in the lower part of the external grille.

Construction: The unit outer case is manufactured from white powder coated sheet metal with a white

ABS internal grille and a grey UV stabilised PVC outer grille. Mains electrical supply: 230VAC 50Hz.

Complies to the following approvals/directives: LVD, EMC and CE.
