Plasticair’s DMF Series of FRP Exhaust Fans have been specifically designed for exposure to gas streams containing corrosive fumes. The rugged mixed flow impeller and robust housing offer favourable features such as corrosion resistant FRP construction for all gas contact parts,high efficiencies and quiet operation. Industries such as Waste Water Treatment, Pulp and Paper, Research Laboratories and Chemical Manufacturing can benefit from this product as it provides Industrial quality, and long life.
The DMF Series is available in fourteen sizes and covers volume ranges of 1300 CFM (614 l/sec) up to 65,000 CFM (30,680 l/sec), and the industrial heavy duty Class 2 construction allows for smooth operation up to 7.25”W.G. (1801 Pa).
Plasticair Inc. certifies that the DMF Mixed Flow Fans shown herein are licensed to bear the AMCA seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 210, publication 300, energy efficiency classification 205 and comply with the requirements of the AMCA certified ratings program.
Shaft and Teflon Seal:
This effective design has completely protects the motor steel shaft from the corrosive gas stream. The shaft is encapsulated with a solid FRP shaft sleeve, which protrudes out from the teflon disk shaft seal, located on the inner tube wall. The teflon seal and shaft sleeve are a machine fit for the best possible elimination of leaking gas.
FRP Housing Construction: Designed for industrial applications, the housing is solid FRP throughout. All FRP exposed to the corrosive gas stream is constructed with a resin rich corrosion barrier complete with C-veil. Airstream straightening blades
are fixed into the housing from the motor plate to the end of inner tube. Motor is completely protected from the corrosive air- stream by the FRP inner tube. Features 6 cooling ducts that protrudes from outside fan housing to inside tube.
Motor is accessible from inner cooling ducts.
Direct drive setup offers best efficiency due to 0% friction loss on drive set.
Fasteners: 316 stainless steel
Flanged outlet: Supplied as standard not drilled
Inlet connection: Slip type, supplied as standard
(Flanged inlet available as option)
Wheel Construction: The DMF Series impeller is of a high efficiency non-overloading design. The mixed flow wheel is constructed of solid vinyl ester resin and reinforcing glass.
