VCOIB Insulated Fans

This type of protection is usually used at temperatures above 150°C, for the purpose of separating the inner zone, at higher temperature, from the outer zone, at room temperature. The upper limit of the application range (200°C – 300°C) should be studied on a case-by-case basis, using high-temperature motors. For more information, contact our technical department. It is not feasible for directly coupled fans (versions 4 and 5) with size 63 motors.

Overall dimensions increase on dimension “B” by ~60 mm for fan versions 4, 1, 9, 12, 8 and 65 mm for fan versions 5. Above 300°C insulation of the entire snail is performed and it is strongly discouraged to use fan versions 4 and 5.
