2 2 General Description The VR series centrifugal fans directly coupled to the electric motor are the result of our experience in the design and construction of fluid-carrying systems. Versatility and reliability are the main characteristics of this series, which is suitable for many areas such as steam intake, drying systems, plastic moulding machines and all applications requiring a small amount of flow with limited pressure. VR Series The housing is in sand-blasted die cast aluminium. The impeller in galvanised plate is the forward curved type. The series is produced in 5 sizes with 108 mm to 180 mm diameter impeller. Available on request with inlet drilling or tapping The fans can have clockwise rotation (RD) or counter clockwise rotation (LG). All of the discharge positions shown on page 12 are possible both using the electrical motor in the B3/B5 form and using a special die-cast base as shown on page 15. In standard execution, the VR fan can convey fluids up to a temperature of 80 C with a relative humidity of less than 80%. When produced in execution (T ), it can convey fluids up to 150 C. Page 12 shows the wide range of accessories available to make installation easier. Electric The electric motors in the VR series are compliant with Unel-Mec standards. They are enclosed with external ventilation and can be flanged (B5), or with feet and flange (B3/B5) upon request. They can be single phase with voltage V 230 / 50 Hz and three-phase with voltage V 230/400 / 50Hz - V 265/460 / 60 Hz. All have IP55 protection and insulating class F. From kw 0.75, IE2 efficiency class. Special voltages in the Eex-d or IE3 efficiency class (NEMA Premium) can also be supplied upon request. Special executions Series VR fans can be supplied with the following variations: - Aisi 304 impeller - all parts in contact with the fluid in Aisi Ral 5009 powder coated housing - Ral painted housing upon request. - Atex group 3, category 2 The performance of the VR fans was measured with outlet ducting according to UNI P fig. 1 and AMCA fig. 7. The impellers are statically and dynamically balanced with electronic equipment according to ISO 1940 grade G=2.5. The selection curves are valid for fluid with a density of 1.2 kg/m3 which is equivalent to air conditions at 20 C at sea level. The sound pressure values LP(A) are expressed in db(a) and are measured in free field at a distance of 1.5 m with a free inlet and ducted discharge. - The information indicated is subject to change without notice -
