D.Fans series industrial large fan is a new type of HVLS energy-saving super large industrial fan independently developed by Dawangfan based on the principle of aerodynamics. It has It pushes 1~3 levels similar to natural wind effect at low speed large air volume and all-round air circulation. It can eliminate high temperature stuffy, balance air humidity, increase oxygen content in the space, smoke and dust removal, low bacterial concentration, effectively solve the problems of stuffy and humid of high and large spaces, air stratification, and persistent smoke and dust.
The features of Dawang D.Fans
1 . High energy-efficient: meet IE2 efficient energy-saving standard, 5~10% energy-saving than that of IE1
2 . High reliability: high axial and radial load capacity to ensure operational reliability;
3．Low noise: low tooth gap assembly process and grinding technology, small vibration, lower noise
4．Low noise: low tooth gap assembly process and grinding technology, small vibration, lower noise;
5 . Pass CCC, CE, UL certifications.
1 . Easy debugging, built-in application macro, no need for self-learning
2． Excellent performance, perfectly matching the operating parameters of the load motor
3．Excellent performance, perfectly matching the operating parameters of the load motor;
4．Safe and reliable, multiple protection programs are set to increase product life.
1 . 5052H32 aviation-grade aluminum blades with thickness 1.5mm, which can withstand more than 3 tons of tension, the blades will not get break down when being impacted.
2．Streamlined fan blade with variable cross-section, it gets narrower and thinner gradually from the blade root to blade tip, the force on the blades is more balanced with smaller wind resistance, making blade move air more uniformly without any holes underneath the fan.
3．More lighter & more safer: it’s only 6.7kgs per blade for 7.3m fan blade, the lighter the safer.
1．Nice mechanical property: made of 6061T6 aviation-grade aluminum plate, after CNC precision machining, perfect appearance & metal streamline to ensure nice mechanical performance.
2．Precise dynamic balance. after CNC machining, the max. tolerance is only 100μm, which can ensure nice dynamic balance performance.
1 . Motor and hub chassis: through the tight connection between the inner tapered bushing and outer tapered bushing, even if the motor shaft is broken, the inner and outer bushings form a structural self-locking to prevent falling.
2．Chassis and petiole: The petiole and the chassis are connected by hook-type mortise and tenon joints, and the bolts are not stressed to ensure the whole structure strength;
3．The petioles are coated wtih polyurethane rubber, which match the buffer cavity of blade perfectly. It can absorb the blade stress & airflow vibration efficiently, and this helps to reduce the motor load and prolong the motor life.
