Features
|
- The Multiflow TDE 500 to 710 range consist of fully cased, cylindrical models with circular mounting flanges at both ends and a wired terminal box.
- Mixed flow non-stall airflow properties and a non-overloading absorbed power curve allow a wide range of operating performance.
- The Multiflow TDE mixed flow fans can typically provide 25% more performance than many conventional fixed blade fans or 25% less space for the same performance.
- Multiflow, mixed flow performance can provide clear benefits over centrifugal and axial fans.
|
Construction
|
- The guide vanes support the drive motor and provide enhanced airflow performance.
- Galvanised steel housing with modern flange connections
- Multiflow’s unique, adjustable blade angle mixed flow impeller.
|
Motors
|
- Electricity supply - Single phase motors suitable for 220 or 240V and 3-phase motors suitable for 380 to415V.
- Single phase variable speed controllable motors with high resistance rotors are available.
- The use of stepped transformers or inverter speed control is also recommended.
- Specification - Output to BS 5000 Part 10, performance to BS 4999 Part 101 and IEC 34-1, dimensions to BS 4999 Part 141 and IEC 72
|
Testing
|
- Air flow tests to ISO 5801:1997 (incorporating BS 848 Part 1,1997)
- Noise data tests to BS 848 Part 2,1985 (Inlet and Outlet sides)
|
Special Features
|
- The required performance can be achieved from a smaller fan size due to the airstream leaving a Multiflow TDE impeller being more axially orientated.
- The casing can then be closer to the impeller periphery, without incurring losses and retaining excellent air performance, power and sound levels.
- The smaller fan size can be used in confined spaces.
- Also, the relatively wide air passage design of the impeller results in greater air movement.
|
Pressure Values
|
- Achieved static pressure is the more commonly used pressure for fans of this type which the accompanying performance curves show.
- Should the fan total pressure be required, use the formula:
