A design enhancement of the Low Profile Fan Powered Terminal Unit Series 37S and 37SST, improves performance on Unit Sizes 1 - 3, allowing for larger fan airflow capacities. The Unit Size 3 airflow range is increased by 300 cfm and is now between 440 cfm and 1250 cfm. A Unit Size 2 with ECM is now added to our selections, for when a more intermediate airflow range is required.
The new design is in effect from May 30, 2017, and we recommend that you review the performance pages and the Selectworks program for more information.
