This is a powerful 550W, 2850 RPM air centrifugal blower fan. It can deliver 10 cubic meters of air per minute at 885 Pascal pressure. You can use this blower wherever high-pressure air is needed. For example, it is effective for paddy drying dryers, paddy cleaning, grain storage, factory ventilation, dust/smoke removal, AC systems, and gas or diesel burners. Not only that, you can use it for onion storage, potato storage, and creating oxygen in ponds. It can also be used for many other purposes. If you need one, feel free to knock. I have used it effectively for 3 months for onion storage. I have sold all the onions, so I don't need it anymore.
