HR100 R and HR100 RS



The HR100R and HR100RS are ideal for single bedroom/bathroom applications such as hotel rooms, nursing homes and residential care homes.

The HR100R features top access and is ideal for loft installations.

The HR100RS features bottom access and is ideal for installation on the ceiling slab above a suspended ceiling.

The unit comes fitted with a single 2-speed motor, and provides continuous low volume ventilation with a boost option. A variety of control devices are available for manual or automatic speed control.

An integral heat exchanger transfers heat from the outgoing stale air to the fresh air supply, raising the supply air temperature whilst at the same time reducing its relative humidity.

Up to 66m³/h FID capacity (extract airflow). As the unit provides superior control of condensation and odours best use would be in bathrooms or small internal rooms.



The HR100R is compatible with 100mm diameter flexible ducting which fits onto the unit via the metal spigots and can be fastened using tape or worm drive clips.

A 22mm diameter condensate drain connection is situated on the base of the unit, this should be connected to a suitable outlet for condensate drainage.

The HR100R comes complete with a four core flying lead for connection to the chosen controller/power supply.
