• -- Double wide impeller with double inlets: large volume, low speed, run more quietly.
• -- Reasonable noise reduction: inlet size recommended by AMCA makes airflow more smoothly with no turbulent flow, so as to bring lower noise. In addition, choosing acoustical lining can reduce noise further more.
• -- New design of airflow channel: Suppress the side noise generated by installation effectively.

• -- Over heating protection: All motor equipped with over-temperature protection device ensure running safety and reliable.
• -- High static pressure: impeller blades special designed according to different characteristic of pros and cons, can increase airflow stability when static pressure changes.

• -- Compact structure: New cabinet design in smaller volume, it is easier to installation and saving space.
• -- Multiple adjustment options: Equipped with three gear variable-speed control, user may choose different volume to meeting the requirements.
• -- Anechoic Centrifugal Cabinet Fan is mostly used in such sites as: (In-Line Cabinet Fan is mostly used in such sites as：hotels, shopping malls, hospitals, theaters, dance halls, auditoriums, colleges and scientific research units, as well as industrial and civil building ventilation etc. Max Volume is 9600m3/h and max Static pressure is 600Pa, supplying seven models totally.

The fan shall be cabinet type, which shall have a Straight drive double inlet centrifugal fan installed inside a cabinet. The wheel shall be constructed of galvanized steel, and statically and dynamically balanced to Level G2.5 as per AMCA204 standard, which shall be backward inclined centrifugal type.

The fan shall be tested in accordance with AMCA Standard 210 and 300. The manufacturer must own the production license for industrial products and ISO9001 quality system authentication.

Housing shall be constructed of galvanized steel. The wall thickness shall be adequate to reduce vibration and noise.

Volute of the fan shall be made of galvanized steel. Its thickness and strength shall be able to bear the maximum operation weight of the fan. It must be equipped with a manhole for removing of foreign matters entering the fan.

Motor shall be carefully matched to the fan load, production class IP20, and insulation class F. Motor shall be inside of the cabinet to be waterproof and reduce sound radiation.

Permanently fixed aluminum nameplate shall be fixed on fan body clearly display fan mark, product model and serial number (i.e.: unique ID for each fan), so that the customer can use this number to find out the parts used.
