Axial fans - duct mounted, short case, long case, plate mounted, or spider frame supported - for practically all applications where air movement and control is required.

• Fan blades are 4, 5, 6 and 7 blades, usually in aluminium.
• Diameters range from 200 to 1600mm, with different pitch angles to suit performance air flows and static pressures required.
• Available in both stream directions.
• Speed adjustable by varying voltage.
• Three-phase and single-phase motors.
• IP55 as standard allowing outdoor use.
• Explosion-proof motors available, according to Atex Directive 94/9/EC, designed and produced according to EN 14986 and EN13463-1.
• Delivery in free air from 400 to 120,000 m3/hr.

Motors are asynchronous three-phase, at single or double speed, or single-phase which can be speed adjustable by varying the motor applied voltage. The electric windings are made in class F insulation as standard, but class H on request.

Motor ball bearings are sealed at both sides with maintenance-free special lubrication and guaranteed for noiseless operation. The standard temperature range is from -30 C° to +150 C°.

Motors may be provided with thermocouples to protect against overheating.
