Product Description
Dynamically balanced, the NBK Replaces the Dayton 6FHX8 (4C446) Blowers, mounts in any position and operates with minimal noise and vibration to maintain CFM at higher static pressures.
This is probably the most used blower in the outdoor wood furnace industry. The NBK Blower is better Quality and will last longer than the Dayton Products. We no longer Carry any Dayton Products.
Typical Applications
This Fan is used on the WoodMaster 4400 & 5500, HeatSource Model 1000 & Taylor T-750, This Fan is also used on the Heatmor 200css & 400css, Heatmor 200SSR2 &400SSR2, Johnson John (Jr models), Freedom Outdoor Eliminator and many other applications.

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
