Centrifugal roof fans with horizontal air exhaust
APPLICATION
- Exhaust ventilation system for various premises suitable for roof mounting.
- Compatible with Ø 200-630 mm air ducts.
- Suitable for any roof types as well as vertical ventilation shafts.
DESIGN
- The fan casing is made of steel with polymeric coating (VENTS VKH models), aluminum (VENTS VKHA), galvanized steel (VENTS VKHz).
MOTOR
- 2-, 4- or 6-pole single- or three-phase asynchronous motors with an external rotor and impeller with backward curved blades.
- The motor is equipped with thermal overheating protection with automatic restart as well as ball bearings for long service life.
