2 AIR HADIG UITS (AHU S) TECHICA IFORMATIO BEEFITS OW DEPTH 185MM The shallowest available, ideal for applications where space is at a premium. HIGH EFFICIECY Heat recovery efficiency in excess of 70% possible, this together with low watt D.C. motors gives all round energy savings. QUIET, COMPACT & POWERFU ow noise levels, compact design and a high performance, provides the perfect engineering solution. ECOSMART EFFICIECY Supplied with Ecosmart control, providing a simple to install, easy to commission, energy efficient solution. PUG AD GO Ecosmart controls and sensors, (please refer to controls section) simply plug directly into the unit and extract then respond to the conditions being monitored. An ES-CI will also be required. FEXIBE SOUTIO Supply and extract airflows are easily fine tuned using integral speed adjustment and built in balancing dampers at each spigot. QUICK ISTAATIO A single point fixing bracket with anti-vibration strip enables quick and easy installation. OW MAITEACE COSTS Heat exchanger block and filters are easily removed from below and cleaned ensuring longer fan life whilst maintaining efficiencies. QUIETEST UIT AVAIABE Acoustically lined with advanced impeller technology, ensuring the quietest system possible. 5 YEAR WARRATY For peace of mind. TYPICA ISTAATIO: OPTIOS ICUDE: Ceiling Grid Mounted Supply Diffuser Ceiling Mounted Extract Grille Extract Air Fresh inlet Easy access to filters. Min and max speed and run on timer adjustment.

The and extract fan will trickle and boost independently

6 AIR HADIG UITS (AHU S) TECHICA IFORMATIO COSUTATS SPECIFICATIO OPERATIO The and extract ventilation unit shall be as indicated on the drawings and shall be in accordance with the particular fan schedule in the specification. Where a stand alone heater battery it will raise the temperature of the air to the design room temperature after the air has passed through the heat exchanger. The ventilation unit shall automatically vary the ventilation rate, as it receives signals from one of the optional interconnected sensors. When signals are received, the fan shall either vary its speed proportionally or on a trickle and boost principle. COTRO OPTIOS All versions shall have the following functions integrally mounted within the fan unit on a purpose made PCB, all such components pre-wired and factory fitted by the manufacturer: - Integral speed control on and extract. Integral background ventilation control/set point. Integral boost ventilation control/set point. Integral run on timer. Integral S/ terminal for boost from remote switch, e.g. lightswitch. The fan unit will have a 5 year warranty. The unit shall have the facility to commission the and extract fans individually via inbuilt minimum and maximum speed adjustment, the fans themselves shall have infinitely variable speed control. Units shall be the as manufactured by uaire. - UIT SPECIFICATIO The fans shall be acoustically lined with high density class O flame retardant insulation, giving extremely low noise levels. The unit shall have a heat exchanger block manufactured from aluminium with a thermal efficiency of approximately 70% which shall be protected by G grade filters on and extract. It shall come complete with a condensate drip tray and drain connection, integral minimum and maximum speed controls, run on timer and facia mounted failure indication. The breakout noise level and power requirements shall be as detailed by the unit manufacturer and as detailed in the ventilation equipment schedule. The unit shall have low energy, high efficiency d.c. fan/motor assemblies with sealed for life bearings. The depth of the low profile unit shall not be greater than 185mm and shall incorporate a low profile single point mounting bracket, with a pre-stressed synthetic anti vibration strip. The unit shall be constructed with two removable panels allowing full maintenance access to all components. To facilitate the interconnection of branch ducts the unit shall have multiple spigot connections with integrated balancing dampers. Spigot connections provided.
