Product features:

• Scientific overall design of the fan, using fiberglass SMC molded shell, in line with air flow characteristics, high air volume, high efficiency, and corrosion resistance;
• Adopting the self-developed permanent magnet brushless variable frequency motor for direct drive fans by Gaofeng, it has high efficiency, wide operating range, strong load capacity, high speed stability, and an intelligent digital control and drive module with built-in microprocessor chip, which is convenient for 0-10V analog control and RS485 interface control. The protection level is IP67 and the insulation level is F;
• The inclined butterfly door design ensures high air volume while improving operational reliability. It uses specially made alloy door panels with high strength, no deformation, and good sealing performance;
• The direct drive structure design reduces the use of accessories and lowers the failure rate. The specially designed blade shape ensures a large air output even under high negative pressure.
