APPLICATION |
|
- Designed to extract contaminated hot air up to 120 °C, containing grease (when using grease filters), in high resistance conditions.
|
- Ideally function in various ventilation systems for:
- restaurant or café kitchens
- industrial bakeries
- removal of gases generated during welding operations
|
DESIGN |
|
- The casing of the fan is made of heat- and sound-insulated two-layer panels made of aluzinc.
- The panels are insulated with 20 mm thick non-combustible mineral wool.
- Connecting spigots, which also serve as vibration damping inserts, can be of square or round cross-section.
|
- Spigots of round cross-section are equipped with rubber seals.
- Connecting spigots are not included in the delivery set, they are ordered separately.
- The electric motor, located outside the air flow, is mounted on an additional panel inside the fan.

ELECTRIC MOTOR |
|
- Highly reliable single-phase or three-phase motor with squirrel-cage rotor and steel high-performance centrifugal impeller with backward curved blades.
|
- The motor is maintenance free.
- Motor insulation winding class - F.
- Degree of protection - IP55.
|
SPEED CONTROL |
|
- Speed control can be both smooth and stepped and is carried out by means of a frequency or autotransformer regulator, several fans can be connected to one regulating device, provided that the total power and maximum current do not exceed the rated parameters of the regulator.
|
INSTALLATION |
|
- The fans are designed for installation with square or round ducts using a flexible adapter of the appropriate cross-section.
- The fan can be fixed with supports, hangers or brackets.
|
- The fan can be installed in any position provided that the arrow on the fan casing corresponds to the air direction in the system.
- During installation it is necessary to provide access for maintenance of the fan.
