The DryTrak Axial Fan is a type of fan designed for use in water damage restoration and mould remediation. It is typically used to help speed up the drying process in areas affected by water damage, such as after a flood or a plumbing leak. The fan works by moving large volumes of air across wet surfaces, which helps to evaporate moisture and promote drying. The DryTrak Axial Fan is often used with dehumidifiers to create a more efficient and effective drying system.
