AAA products feature a low-noise forward centrifugal fan, along with components such as a motor, bearing, transmission parts, and a muffler box. To accommodate various installation requirements, there are 12 different inlet and outlet angle options available. These products are categorized into two types based on firefighting and ventilation needs: Type A and Type B. Type A motors are externally mounted for firefighting and smoke extraction, capable of continuous operation for over 60 minutes at temperatures reaching 300℃. In contrast, Type B motors are housed within the unit for ventilation purposes.

The fan lineup includes 12 specifications based on diameters ranging from 9" to 36". The airflow capacity spans from 1650 to 85000 m3/h, with total pressure ranging from 180 to 1000 Pa. Following ongoing enhancements, the HTFC cabinet centrifugal fan is classified into four types: I, II, III, and IV. Types I and III operate at a single speed, while Types II and IV feature dual-speed motors, allowing for two-speed regulation to meet varying performance demands under different operating conditions. Additionally, the fan can be fitted with a variable frequency motor and controller for seamless speed adjustment, with a recommended frequency lock between 25Hz and 50Hz. 

Note: If the motor is on the top of the box, if the motor frame size is more than 200, the motor should be placed at the bottom. If the motor still needs to be placed on the top of the box, please indicate when ordering.

Remarks:  

1.H and L are the overall dimensions of air outlet No. 14~12; H1 、 L1  Is the overall dimension of the air outlet No. 2 and 

2.The width of type a fan box does not include the width of belt cover; Height excluding motor height.

3.If the motor is on the top of the box, if the motor base number is  ≥ 200, the motor shall be placed under the box. If the motor is still placed on the box.

Configuration

To accommodate the demands of an explosion-proof environment, the fan can be designed as an explosion-proof unit. It has a coal proof rating of EXdllBT4, making it suitable for areas where flammable and explosive gases are present. 

To address noise requirements in various settings, the fan can be fitted with mufflers of varying lengths, and the fan muffler box can be reinforced to further minimize noise levels. 

Additionally, the fan can be outfitted with primary, medium, or separation effect filters to enhance air cleanliness. When selecting filters, it is essential to take into account the actual pressure loss, and the length of the fan box should be adjusted accordingly.

The Processing Technology

1.The impeller and casing of the fan are of high quality galvanized sheet, all of which are moulded and produced by means of riveting and biting. The surface is clean and smooth, and there is no welding deformation phenomenon. 

2.Fan type silencing box body framework, corrugated board assembly design, the framework USES the advanced metal cold bending unit time stretching and aluminum profile is used for (also can according to user needs), Box board for color coating board (galvanized sheet), surface clean and beautiful, corrosion resistance is strong, the inner for acoustical micro perforation plate, galvanized sandwich superfine glass wool, can reduce noise - step. The product can be disassembled and installed on site.

Shipment

My shipment arrived early than with the expected date. Everything according to package was safely shipped to me with no defects. The supplier was excellent enough to satisfy the customer’s needs.
