This fan-forced sub-floor vent chassis fits into a space of two (2) bricks high, by one (1) brick wide. With a 20mm flange that is integrated into the louvered model, fits snuggly into the space that is occupied by a terra-cotta (TC) vent. The solarpanel occupies a space on the roof of 400 x 300. This system does not store energy but works directly when the sun is on the solarpanel which generates power to the quad fan system. The Solar concept is ideal where dry air is to be induced into the sub-floor area and when it is damp and rainy it does not activate. A kit comprises of 1 x quad fan system (white or brown) 1 x solarpanel (SP4) to operate the quad fan system and 12m of low voltage cable (LVC) and connectors (minimum order for this product is (2) kits.)
The Envirofan Quad Fan extracts 5,500 litres per minute (5.5m3/min) of damp air, and is the quietest system in its class. Cost to run is free energy from the sun so it leaves no carbon footprint. This system is ideal for applications where a standard passive terracotta brick vent is to be replaced.
