Product Description
Dynamically balanced, the NBK Blower Replaces Dayton Models 1TDR3 (4C447) Blower mounts in any position and operates with minimal noise and vibration to maintain CFM at higher static pressures.
Dayton Blowers 1TDR3 PSC Draft Fan Blower, 115 Volt. The NBK Blower is better quality and will last longer than the Dayton products. We no longer carry any Dayton products.

Features
- Dynamically balanced blowers provide smooth and quiet operation.
- Noise and vibration are held to a minimum to maintain CFM at higher static pressures. Motors have cast aluminum end shields for greater heat dissipation and protection, resulting in less downtime and longer service life.
- UL and C-UL Recognized (E47479), except No. 2C646 is not UL or C-UL Recognized, and No. 2C647 is UL Recognized (E22286) and CSA Certified (LR12645).
- Direct replacements for many OEM blowers with same physical footprint
- All-position mounting
- Min./max. operating temp. range: -20 Degree to 104 DegreeF
- Max. inlet and ambient temp.: 104 DegreeF
- Motor enclosure: open
- Replaces the Dayton 1TDR3 and 4C447
