Inline Duct fans and mixed Duct fans are the appropriate selection where space is at a premium. These duct type fans can be used as either exhaust air or supply air depending on what is required. Typical applications for duct fans include enclosed garages, spray booths, heat & smoke ventilation or any space where air is moved through ducting. Square Inline Duct fans are the right choice where space is limited. The compact housing with removable access doors can be mounted in any place. Multi-Purpose Duct fan applications include: bathrooms, kitchen range hoods, utility rooms, cafeterias, offices, welding fume extraction, equipment cooling, workshops and smoking areas. Industrial Fans Direct carries the right inline duct fan for most commercial and industrial application.
