#Terminal Units

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.

Unique to Nailor, the “Stealth^™” Induced Air Dissipative Silencer option provides maximum acoustic attenuation by reducing radiated sound power levels. The medium insertion loss design does not however affect fan performance.  When units are installed above the occupied space, the addition of the silencer reduces the radiated sound level in the occupied space by a significant 5 NC. It is available as standard with Fiberglass Media. A Mylar/Spacer Liner option is also available for IAQ sensitive applications.
