LBF is a range of straight flow in-line centrifugal duct fans designed for circular ducts. They are compact, high capacity fans which operate quietly and can be fitted in any position.
LBF fans have forward curved impellers and are designed to cope with high pressure and long duct.
The fans have a rigid housing made from galvanised steel. They are moisture proof and approved for use in outdoor environments. The motors are maintenance free and protected from overheating by thermo contacts. The impellers only require occasional cleaning. This cleaning is made easy with the LBF's swing out design. All fans are supplied fully wired and ready to fit in a sealed installation unit with an IP44 protection class.
