DUBAI, UAE, 9 November 2022: Dunli launched the B-Max backward-curved centrifugal fan, saying that it developed the fan for the purposes of high-end HVAC unit applications.

Making the announcement through a Press release, Dunli said the impeller, motor and controller of the fan feature a brand-new design that brings the customers a better user experience.

According to Dunli, the B-Max facilitates easy installation. The fan is a one-piece solution, where the motor, impeller, inlet ring, supporting rack and mounting plate are matched and assembled perfectly with one piece, which enables the customer to assemble the fan easily, Dunli said.

The fan also has excellent efficiency, Dunli claimed. The fan has industry-leading static pressure efficiency, which meets ErP2020 Standard requirements, Dunli further claimed. The fan also has aerodynamic efficiency as high as 75% and above, Dunli said, adding that it features a compact-structure external rotor EC motor and that the efficiency of the motor meets IE4 standard.

Dunli said the fan has optimised, aerodynamic, airfoil-shaped blade design, achieved through using CFD technology. The company further said, the fan has industry-leading noise level and that it has gone through over 40 reliability tests.

Additionally, Dunli said, the fan has a plethora of control functions, including 0-10VDC (15VDC)/PWM signal control. It also features phase-missing, over-current, over-voltage, over-temperature protections, and signal control and fault alarm functions, Dunli said. It also features 485 communication functions with MODBUS-RTU interface to monitor working, stop, speed and malfunction of the motor status, the company said.

According to Dunli, the fan lends itself to a wide range of applications and can be used for AHUs, and in data centres and environment that require precision air conditioning.
