8 CENTRIFUGAL ROOF FANS - ACCESSORIES Speed Controllers - speak to our Technical Department to determine which controller to use (cannot be used with explosion proof fans). Soaker Sheets - A full range of the most commonly used profiles is available for all fans sizes. Manufactured in glass fibre, they offer a convenient method of weatherproofing for profiled roofs. Purlin Boxes - These are available for use with soaker sheets to provide a solid fixing for the fans to the roof support structure. They are manufactured in galvanised steel (dimensions page 3) OTHER VECTAIRE INDUSTRIAL / COMMERCIAL / DOMESTIC PRODUCTS Roof Mounted Axial Fans Plate Axial Fans Long Cased Axial Fans Centrifugal Fans In-Line Fans Air Handling Units Built-in Wall Fans Window / Wall Fans Toilet / Bathroom / Kitchen Fans Vectaire Ltd Lincoln Road Cressex Business rk High Wycombe Buckinghamshire HP12 3RH Tel: +44 () Fax: +44 () Vectaire Ltd reserves the right to alter specifications as part of its policy of continuous development.
