The Primary element is of the pleated washable type, with Secondary elements either HEPA, Micro-Cell or Hi-Cell.The units are designed to accept any standard dimension proprietary filter combination.Manufactured in three dimensions, the range extends to six variations by selection of appropriate filtration media allowing for standard dust protection with filter efficiencies ranging from 80% through to 99%.The CLEANPACK range of Standard and Heavy-Duty fan-filters units meet the demands of varied applications requiring dust free and clean air conditions utilising standard production componentry such as fans and filters.Should the fan total pressure be required, use the formula:.Achieved static pressure is the more commonly used pressure for fans of this type which the accompanying performance curves show.Also, the relatively wide air passage design of the impeller results in greater air movement.The smaller fan size can be used in confined spaces.

The casing can then be closer to the impeller periphery, without incurring losses and retaining excellent air performance, power and sound levels.The required performance can be achieved from a smaller fan size due to the airstream leaving a Multiflow TDE impeller being more axially orientated.Noise data tests to BS 848 Part 2,1985 (Inlet and Outlet sides).Air flow tests to ISO 5801:1997 (incorporating BS 848 Part 1,1997).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.The use of stepped transformers or inverter speed control is also recommended.Single phase variable speed controllable motors with high resistance rotors are available.Electricity supply - Single phase motors suitable for 220 or 240V and 3-phase motors suitable for 380 to415V.Multiflow’s unique, adjustable blade angle mixed flow impeller.Galvanised steel housing with modern flange connections.The guide vanes support the drive motor and provide enhanced airflow performance.Multiflow, mixed flow performance can provide clear benefits over centrifugal and axial fans.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.Mixed flow non-stall airflow properties and a non-overloading absorbed power curve allow a wide range of operating performance.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.
