Mixedflow Vertical Discharge Rooffan

Main features• Very high efficiency.• Very low noiselevels.• Mixedflow impeller (axial+ centrifugal).• All fans are speed controllable as a standard.• Motor out of airstream. ( IP 55, Insulation class F ).

and incl. of overload protection.• Wide range of ambient working temperatures

- 30/ +100 oC.• The fan is totaly recyclable.• The casing is not vulnarable to deformation or breakage.

ImpellerThe unique mixedflow impeller consists of two aluminium dis-hes with polyamide blades which, because of the very specialshape and positioning between the dishes, gives the impellerits charasteristic axial and centrifugal mixedflow design.

CasingThe casing is made of HDPE (High Density Poly Ethylene.Colour light beige) and is 100% recyclable and resistantagainst all weather conditions.

All fans are supplied with a birdscreen on the discharge side.

WiringThe fans are supplied with either a service switch or serviceswitch with thermal overload protection mounted on the unit.

Noise All noise figures are shown on the technical data sheets foreach fan.

Special applicationAcid resistant fans are available with all metal componentseither specially coated or made of stainless steel.

Flameproof fans are available upon request.

All fans are measured as per BS 848 part 1
