If you are installing a new ventilation system or bathroom fan, both are clever investments and require specific products. Bathroom fans are advantageous for reducing damp in the house as the damp is removed and risk of mould damp decreases. You will need a fan, vent pipe and a framed louvre vent or similar for outside. A fresh air vent is a simple way to ventilate that has a great effect when a more comprehensive ventilation system is not needed. With a fresh air vent, you can use a screen vent or a traditional round air vent. Air vents, ventilation ducts, hose connectors and fittings are needed for all ventilation installations. At Clas Ohlson, we have a wide range of products for supplying and extracting air in your home.
