Mixed Flow fans are an excellent choice for return air, supply, or
general ventilation applications where low sound is critical. As
compared to similarly sized tubular centrifugals and vane axials, a
mixed flow fan will be 5-20 dB quieter! In addition, the mixed flow
wheel is extremely efficient and will cut down on operating expenses.
Unique features of the MVA Mixed Flow Fans include:
- Universal Mounting System that allows the unit to be field rotated at
the job site
- Compact design with standard slip-fit duct connections for ease of
installation
- UL/CSA listing for electrical is available
- Continuously welded housing with a standard powder paint finish
suitable for indoor or outdoor applications
- A complete three plane vibration test of all assembled fans prior to
shipment
Model MVAB:
* Belt drive construction with motor out of the airstream
* Air Handling Quality bearings selected with a minimum life in excess
of L(10) 50,000 hours at the maximum operating speed
* Performance capacities from 1,000 to 100,000 cfm (1,700 - 165,000
m3/hour) and pressures up to 8 in. wg. (2000 Pa)
Model MVAD:
* Direct drive construction eliminates belts, pulleys, and shaft
bearing maintenance
* MVAD design is more compact for space critical application
* Partial wheel widths allow for wide performance capacities ranging
from 500 to 105,000 cfm (900 - 170,000 m3/hour) and pressures up to 9
in. w.g. (2300PA)
Another in-line fan for for air moving in round ducts by Canada Blower
is a high pressure small vaneaxial fan finally resolves the problem of
boosting air flow in long ventilation ducts of today's large
residential houses.
