Hi I'm working on a project where I would need to lift about 400 pounds about 1 inch off the ground and keep the momentum in order to manually move it. I thought about using four fans with a skit on each corner facing downward to allow for upward movement, but I'm not sure how much power I would need the fan to be at or what calculations I would need to figure out the specifications. I also thought of using four air compressors but was unsure if I could keep the continuous air flow. Any suggestions would be extremely helpful! Thank you!
