Industrial centrifugal fans with backward-bladed impeller SVM series
Industrial centrifugal fans with backward-bladed impeller SVM series are made as follows:
- steel cochlea equipped with flange connections on the suction and pressure ports, with fully electro-welded and blue powder coated structure
- chair for motor-impeller unit support connected to the augers with bolted plate for quick impeller extraction in case of maintenance
- electrowelded steel impeller, statically and dynamically balanced with cast iron hub with flat backward running blades
- electric motor suitable for outdoor installation, can be driven by 3-phase inverter.
They are offered from stock in 7 sizes from 250 to 450 all with 2-pole motors, but are also available up to diameter 1000 with 4- or 6-pole motors.
Application
For suction and conveying of clean or dusty air, with low-medium-high flow rates and low-medium pressures, sawdust, various chips, granular materials, excluding filamentous materials. Within the SECURAIR® program they find, for example, use for suction from self-supporting arms (when not already equipped with an on-board exhaust fan) or for making suctions with industrial hoods as shown in the image below.
Centrifugal fans can be complemented by a range of SECUREAIR accessories (The product photo refers to the version complete with all accessories) designed to facilitate their installation:
- circular fittings on suction and discharge, solving the problem of connecting fans to plant piping
- galvanized base frame for ground installation, complete with shock absorbers to reduce transmitted vibrations
- galvanized steel bracket for wall mounting, complete with shock absorbers to reduce transmitted vibrations
- vibration damping joints on suction and discharge, to reduce vibrations transmitted to the plant piping
Remember that when ordering for all centrifugal fans it is necessary to determine the direction of rotation of the impeller, also known as "orientation." Looking at the fan from the side of the electric motor, the possible positions of the air delivery port are defined, according to international standards, by an alphanumeric abbreviation in which the literal part (RD - right or LG-left ) indicates the direction of rotation of the impeller and the numerical part indicates instead the angle in degrees of airflow exit from the delivery port.
There are 16 orientations available, n.8 clockwise (RD) and n8 counterclockwise 8LG) remembering that the direction of rotation is defined, in a centrifugal fan, by looking at the fan from the motor side.
A correct choice of orientation is crucial for the fan to work with maximum efficiency and to avoid turbulence in the piping.
Our technical department is available to support you in making the correct choice.
