HR30W

Overview
The HR30W has been specifically designed to provide balanced ventilation with heat recovery for installation in bedrooms giving virtually silent overnight operation with a daytime boost option. Low velocity and low noise heat recovery ventilation with a pollen filter for improving the internal environment.
The HR30W is a through the wall model, with a range of control and length options. The unit 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.
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.This provides control of condensation and odours and creates conditions which can eliminate house dust mites.
Two speed performance: Low 35m³/h and High 50m³/h. Specifically designed for installation in the bedroom.
Installation
Vent-Axia HR30W units require a 240mm x 160mm hole. Units should be fitted so that they slope 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.
Maintenance
Apart from removing odours, providing fresh air and recovering heat, this appliance extracts airborne impurities such as dust, dirt and grease. These gradually build up and detract from the efficiency and appearance of the appliance. Therefore to ensure peak performance, the appliance should be cleaned regularly. Filters should be replaced every six months or as conditions necessitate. The heat exchanger and grille should be washed in warm soapy water every twelve months or as conditions necessitate.
Extension Sleeve - EXT100
For installation in walls from 280mm to 500mm thick. Supplied with white ABS plastic external 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 2speed 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.
Ducting spigots: The unit should have 4 spigots, 2x150mm Ø to atmosphere and two 200mm for circulation inside the property.
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.
Sound Levels: Refer to above table.
Mains electrical supply: 230VAC 50Hz.
Complies to the following approvals/directives: LVD, EMC and CE.
