The problem
The existing 9,000 cfm unit was jammed up in a mechanical room with virtually no room to replace the unit. The only way to replace it would be to provide a complete knockdown custom air handling unit.
The solution
There was plenty of room above the AHU to install Q-PAC ECM fans on top of the unit and field manufacture a plenum box with access to each fan. Sometimes you just have to think outside the box.
