Exhaust fans

The fan blades are precision-stamped from Krupp stainless steel, ensuring a dust-free surface as well as aesthetic appeal and durability.

The unique blade profile is engineered to deliver a high airflow volume while remaining resistant to deformation and breakage, thereby ensuring a consistent and uniform air volume across the entire airflow path.

• Both Chinese-manufactured motors and Siemens motors are available as options.
• The motor voltage and frequency can be customized to meet specific requirements.
• The Chinese-manufactured motors feature a specialized design tailored for fan applications; notably, they are the first in the industry to incorporate a phase-loss protection device that automatically cuts off power in the event of a power supply anomaly.
• The motors carry an IP55 protection rating and an Insulation Class F rating.

• The fan pulley is die-cast from a high-strength aluminum-magnesium alloy, which reduces overall weight while maintaining the structural integrity of the impeller assembly. The pulley features a reinforced rib design that enhances its inherent rigidity and stability, ensuring it remains shatterproof.
• The fan bearings utilize a double-row configuration with a waterproof seal design, effectively preventing water ingress. These bearings offer high structural strength, low noise operation, are maintenance-free, and boast an exceptionally long service life.
• The fan employs a nylon centrifugal shutter-opening mechanism, ensuring that the shutters open and close smoothly and reliably.
• The fan belt is constructed from high-strength material, guaranteeing a long operational lifespan and requiring no maintenance.
