The Alpine Ventilation range of subfloor vent kits is an easy and low-cost DIY way to remove moisture from under your house. There is a 150mm and a higher capacity 200mm version. Each consists of an axial fan with a power cord, an aluminium exterior vent with a neck adapter, ducting, timer and clamps, duct tape and hanging tape – everything that should be required for most installations. The kits can be extended with the use of Y pieces and additional lengths of ducting. The fan can draw in dry air from outside and force out the moist air through other vents – or it can be reversed to extract the moist air and have dry air from outside replace it via other vents in the subfloor.ContentsBrick-sized aluminium louvre vent with mesh and 150mm neck adapter2m x 150mm d rectangular ducting150mm Axial fan (with plug)Timer30m x 48mm duct tapeDuct hanging tape3 x 150mm steel clamps
