The SQN has the shortest depth of any available square inline fan. Standard universal mounting feet allow the customer to have total control of the fan’s installation without the need to purchase any mounting accessories. Three access doors allow total access to the fans internal components in any vertical or horizontal mounting installation. By utilizing the side-discharge options, installation costs, pressure loss, system effect, and space requirements are reduced. (Side discharge options are illustrated on page 10) The SQN-B, SQN-HP, and SQN-D are licensed to bear the AMCA Certified Ratings Seal for Air and Sound Performance.
