National Ventilation has launched its Monsoon Energysaver™ IntelliSense i7 fan. A clever multi-function fan, the 7 in 1 IntelliSense i7 bathroom fan is the intelligent choice for wholesalers, electricians and households alike. With a choice of intermittent or continuous running, this ultra-quiet, ultra-modern, smart bathroom fan runs extremely quietly at low speed at just 17dB(A). The ingenious fan also offers an intelligent humidity sensor, a useful overrun timer and presence sensor, an airing function to avoid stuffy odours in the bathroom, while offering a high performance of up to 110m3/hr.

Versatile enough to ventilate bathrooms, toilets and utility areas, the 7 in 1 IntelliSense i7 boasts six core ventilation modes including: three continuous ventilation modes; three intermittent modes; plus, one heat mover mode that allows the fan to transfer surplus heat to an adjacent room. Suitable for installation in wet areas (IP44) such as WCs and bathrooms the fan offers further installation flexibility since it is suitable for both wall or ceiling mounting. This makes IntelliSense i7 the ideal choice for electrical wholesalers, who can offer this intelligent fan to their customers, confident that with its 7 in 1 options the fan’s versatility means it will fit the majority of bathroom installations. With one fan suitable for most installations, it also means wholesalers can hold less stock in their warehouses. Meanwhile, electricians can keep the fan in their van knowing they will always have the right solution for their customers to hand and that they can also expect happy customers thanks to all its intelligent features.

“The new Monsoon Energysaver™ IntelliSense i7 is quiet yet versatile and with its 7 in 1 options, wholesalers and electricians can be confident that they are making the right choice”, said Robin Francis, Managing Director at National Ventilation. “It also offers reduced energy consumption due to a low-voltage motor – using about a third less than conventional bathroom fans. Plus, the IntelliSense i7 is only manufactured with materials that have a low environmental impact. All in all, the IntelliSense i7 fan is the intelligent choice.”

The IntelliSense i7 is stylish yet great value and is packed with clever features, all backed up by a 5-year warranty which will be attractive for households. To help protect a home from condensation and mould the fan boasts an intelligent self-adjusting humidity sensor which continuously measures the humidity level in the room. When it senses a sharp rise in humidity (e.g. when taking a shower) or if the relative humidity (RH) exceeds 70% it starts up automatically. When the humidity level is restored, the fan returns to basic flow or stops. Meanwhile, a useful presence sensor is activated by motion (IR) or when the light is switched on to ensure the fan operates when the room is in use. The over run time is 15 minutes with the fan switching to a medium speed, 60 m3/h, and depending on the choice of mode, it starts up immediately or after 2.5 minutes. However, if the humidity control or presence sensor has not been active for 24 hours, the airing function will start up with the fan operating at medium speed for 30 minutes every 12 hours. This avoids stuffy, musty odours in the bathroom when the room is unoccupied for a while.

Offering excellent performance with a high capacity and very good pressure capability, the IntelliSense i7 also features a unique self-calibrating motor that senses and compensates its speed if, for example, wind resistance increases in the ventilation duct. It can be compared to a built-in cruise control that automatically ensures an optimal ventilation flow and avoids backdraughts even when the fan is running at low speed.
For electricians install is made easy. Suitable for both wall and ceiling mounting, once the wall frame is installed the fan is simply fixed to the wall frame, phase and neutral are connected and the job is done. The fan offers plenty of space for electrical connection; a liftable terminal block; has integrated seals around the back side of the wall frame and cable and screw entries; and a built-in multi-pole switch. Changing the function is made easy too. Simply lift the cover plate, select the desired mode with a screwdriver and close the cover. It’s also possible to change mode when the motor unit has been removed from the wall frame.
