Audited Supplier Ywl4d-250qd 250mm AC Single Inlet Centrifugal Ventilation Blower Fan for Kitchen
YWL series centrifugal fan is a new type of centrifugal fan developed and produced by our company absorbing advanced technology at home and abroad. It has the advantages of small size, large air volume, high efficiency, low vibration, low noise, convenient installation and debugging, etc.
The gas transported by this series of fans is not allowed to contain viscous substances, is non-corrosive, non-flammable and explosive.
This series of fans are widely used in civil, industrial buildings, laboratories, etc. for ventilation, environments with strict noise requirements, as well as in air conditioning, purification, and refrigeration industries.
This kind of fan can be made of pp, carbon steel, stainless steel, glass fiber reinforced plastics, and Stainless steel centrifugal fan has beautiful appearance, good stability, easy to maintain, its structure is compact. The optimized impeller reduces the axial force to a low degree. With static and dynamic balance checking, which makes the whole machine run smoothly. Without any vibration reduction equipment, the bearing amplitude is small, which ensures the stability of the operation of the equipment.
When the stainless steel centrifugal fan is running, there is no mechanical conflict, we choose reasonable blade shape line to reduce the sound to be lower. Stainless steel centrifugal fan has good heat resistance and certain corrosion resistance.
The centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas changes to the radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of flow and the increase in the cross-sectional area of the duct slows down the gas flow, which converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller, and secondly in the diffusion process. In a multi-stage centrifugal fan, a recirculator is used to move the airflow to the next impeller, creating a higher pressure.
