An AHU with 20 HP motor is supposed to supply 26,000 cfm cold air to an open office area. During the testing and commissioning stage, it was reported that the air velocity taken at the duct (48”x 36”) is 1,800 fpm. The running current taken was 20.1 A. The motor pulley size is 6” whereas the blower pulley size is 4”. The full load current for that particular motor is 28.1A and the rpm 1455. Please comment.
