DDE Centrifugal Blowers

Direct Driven DDE blowers designed to range of high efficiency  and low noise, with capacities from 400 m3/h to 7000 m3/h, matching various housing + wheel sets with a wide selection of FHP motors.  The direct driven solution, avoids extra costs, risks and maintenance which are peculiar of the belt driven design.  The DDE blowers have to be installed in weather protected environments to operate with powder free air, and with room temperatures ranging from -30°C to +40°C.  Standard models are available either with "open" motors (protection class IP20) or with "totally closed" motors (protection class IP54), with one or more speeds, with 4 or 6 poles.  The DDE blowers are supplied with the capacitor lready connected, assembled to the housing when using "open" motors, or inside the connection box by "closed" motors.

All motors have insulation class B, and are equipped with pre-lubricated maintenance free sleeve bearings.  They are designed and manufactured in accordance to the Direttive Bassa Tensione and Compatililita Elettromagnetica, as well as to the Direttiva Macchine, according to CENELEC EN 60335-1 Standard Norms. 

Housing and wheels (these last static and dynamically balanced) are manufactured with galvanised steel plates to avoid any corrosion process.  

The blowers can be supplied without fittings, with a set of 4-positions support feet, or with a preassembled flange on the air blowing outlet.  For trouble free operation it is advisa le to check, before starting, that no foreign matters eventually dropped into the housing.  It is also required not to operate the blowers as "free blowing" (no pressure drops) to avoid motors' overheat.
