Inquiry (采购产品): custom job I am looking to develop a vertical wind tunnel and I need an air handler for this unit. The purpose for this unit is to simulate freefall from skydiving. The area will be a 10 ft radius and I will need the maximum velocity of the air flow to be about 140 mph. I believe just over a 1 million CFM. The drive unit could either be direct drive or electric motors. I am also looking for the most efficient use of power for air flow and keeping it at the lowest db rate. Let me know if you are able to help me.
