Provides Continuous Background Ventilation To Combat Condensation

Kair^TM Flat Input Ventilators have been designed to create a continuous positive air pressure (providing a capacity to move in excess of 100m 3 per hour). This will effectively combat condensation dampness and mould growth and meets or contributes towards the F1 Building Regulations requirements for ventilation. 

Condensation occurs when the water content of air rises above a level called the ‘dew point'. At such time, water droplets will form on the coldest surfaces i.e. window, external walls etc. On average, a family of four people will produce about two gallons of water vapour per day from activities such as cooking, bathing, breathing and the washing and drying of clothes. 

It is also a fact that nowadays most properties are insulated to prevent warm air from escaping. This reduction in ventilation allows the air contained within the property to reach a higher relative humidity.

Kair^TM Flat Input Ventilators will help provide protection for hygroscopic material such as wallpaper, books, leather goods, wooden furniture, clothing and other fabrics from mould.

Please note that this unit is protected by system zero security screws. Either a tamperproof bit or tamperproof driver is required for installation.
