Low Noise Type Cabinet Fans are ducted ventilating fans with both intake and outlet opening fixing at interior and exterior of the house respectively. They can be used as single port or multi port to exhaust air from several areas with one unit. Since only a small ventilation opening is required, the appearance of the interior is not spoiled.

All models are manufactured from galvanized steel enhancing high durability. The unique suction fan design and acoustic noise absorbing material realize low noise operation. The high performance induction motor offers low consumption, long life and high reliability.

The slim, compact and light-weight structure allows easy installation at narrow ceiling space. Those units can be installed upside down, that location of inspection opening can be selected to ensure easy access for maintenance. Particular U-grooved mounting brackets prevent loosen of mounting bolts that reinforce installation safety

Wide range of models, either single/double speed or single/three phase, are available for different requirements

• Long life condenser motor with thermal cut-off
• Twin flow fan
• Fan casting with tapered scroll
• Embedded terminal box
• Noise absorption material adopted
• Compact size

Twin Flow Fan

The newly developed twin flow fan achieves a better air flow inside the fan casing.

It is divided into two portions which can generate large air volume and high static pressure respectively

Tapered Scroll

Wind velocity varies according to the shape of fan casing. The tapered scroll at the fan casing can minimize the turbulence induced by uneven wind velocity insice the casing

Embedded Terminal Box

Terminal boxes of new models are embedded into the product frame.

Wiring to power supply are covered with metal enclosure that enhances the durability and safety concern
