Instruction LPMA 1. General The LPMA fans are suitable for air conditioning as well as for industrial installations. The air flow range of the LPMA fan is up to 7 m3/s (25 000 m3/h),­pressure increase up to 600 Pa (60 mm vp). The LPMA fan is available in two models: LPMA-1 for mounting to wall LPMA-6 for connection to duct The fan motor is located directly in the air flow. Therefore the temperature of the transported air is limited to 40°C. The air must not contain aggressive or explosive components. The fan is, as standard, manufactured for 3-phase operation. The LPMA fans can, in some cases, be used for stepless speed regulation. See next page. 3. Design LPMA-1 contains a 3-phase asynchronous motor, placed on a strong bracket. The wall ring has a stream lined inlet and is provided with four lugs for mounting to wall. Both wall ring and bracket are manufactured of galvanized sheet steel. LPMA-6 contains a 3-phase asynchronous motor, placed on a strong bracket. The casing is manufactured of strong galvanised sheet steel and is, in both ends, provided with connection flanges. The casing is provided with inspection door and cable entry. 6. Optional accessories LPMA-6: Protective louvre Plastic flexible connection Flange GOCA POAA FODA 4. Axial fan propellor The blades of the LPMA propellor are manufactured of plastic and its' hub is of silumin. The propellor has a temperature working range of –40°C up to 80°C. The propellor can, for special cases, be delivered completely in silumin. 5. Maintenance Check necessity of cleaning of fan and motor at least twice per year. Depending on the type of dirt the fan is vacuum cleaned or cleaned with a mild, non-corrosive detergent. The motor is brushed off or gently cleaned with a mild, non-corrosive detergent. Specifications are subject to alteration without notice.
