The Integra heat recovery unit has been specially designed to provide ventilation for flats or internal rooms in residential, commercial, educational or leisure applications. Balanced ventilation is achieved by using nominal 100mm diameter ducting. The unit is completely self contained and includes two integral centrifugal speed controllable fans plus a high efficiency polymeric heat exchanger.

Using a high performance, polymeric heat exchange cube, together with two powerful fans, the Vent-Axia Integra boasts a temperature efficiency of up to 70%. The compact cube interleaves outgoing moist air with incoming fresh air, allowing the heat from one to warm the other without the two air streams mixing. Energy is saved on room heating, with no power being used by the cube itself.

Performance of Integra: Up to 49 l/s FID. Ideal for installation in the ceilings voids or cupboards.


Easy Installation

The Vent-Axia Integra is designed for mounting in ceiling voids, lofts or above a suspended ceiling. Four 100mm spigots are provided for simple connection to insulated flexible or rigid ventilation ducting. The unit comes complete with a 22mm condensate outlet.

Typical Specifications

Supply and install an Integra Wholehouse heat recovery unit as manufactured by:

Fleming Way
West Sussex
RH10 9YX

Performance: m³/h l/s
Max ventilation rate 175 49
N° speed settings 6

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 240V 50Hz A/C with sleeve bearings, greased for life. It shall operate up to an ambient temperature of 40°C and be fitted with a manual reset thermal overload protective device.

Fan: The fan impeller should be of a forward curved centrifugal type, dynamically balanced.

Controls: The unit should be powered via a remote multi-step transformer that provides a switch gate between a selected slow speed and boost condition. The switch can be a manual or sensor type or a combination of both.

Ducting spigots: The unit should have 4-N° 100mm Ø x 50mm spigots. (Can be converted to flat ducting).

Filter: not fitted.

Condensation: the outlet provided should be 22mm Ø located on the underside of the unit.

Construction: the unit outer case should be a rigid black ABS moulding.The case should split along a horizontal joint to allow maintained access.
