The Vent-Axia HR100W range is designed for continuous operation providing up to 70% Heat Recovery. Effectively controlling internal relative humidity. The Vent-Axia HR100WH unit come complete with
integral humidity sensor and controls condensation and reduces mould.
Fresh pre-warmed air from the outside is continuously provided to the room with simultaneous extraction of stale, moist air.
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 to the room.
The HR100WH has a two speed motor which provides for constant low rate
ventilation automatically switching to boost speed on rising humidity level of approximately 70% relative humidity at 20°C. This level can easily be adjusted by removing the front cover and heat exchanger to reveal the adjustment spindle.

HR100W units require a 240mm x 160mm hole. The unit should be fitted so that it slopes towards the outside (nominal 1°) to assist in-built condensate drainage.
The telescopic flange (adjustable to fit walls 220mm to 280mm thick) covers cutting marks and provides a surface for forming a seal with the external wall surface. An extension sleeve is available for thicker walls up to 500mm. (Stock Ref. 370419)
Filters should be replaced every six months or as conditions necessitate. Replacement filters can be purchased in packs of four. (Stock Ref. No. 37 03 78).The heat exchanger should be washed in warm soapy water every twelve months or as conditions necessitate. Access to the filter and heat exchanger is via two screws on the internal grille.

Efficiency: The unit should retain up to 70% of the temperature differential of out going air.
Heat exchanger: Should be of a multi plate cross-flow type constructed out of a polymeric plastic with ultra sonic welded joints.
Motor: Should be a 2 speed 240V 50/60Hz A/C with sleeve bearings, greased for life. It shall operate up to an ambient temperature of 40°C and be fitted with a one shot thermal overload protective device.
Fan: The two polymeric fan impellers should be a centrifugal forward curved type, dynamically balanced mounted on a common shaft.
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 washable reticulated foam type coarse filter.
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.
