Fan Noise Suppressor

Grain storage facilities like to be good neighbors, and sometimes that means reducing the noise generated by aeration fans.

Safe-Grain, Inc. is an experienced designer of custom fan noise suppressors using standard components. We do this routinely, and can provide a custom solution to meet the requirements of your applications. Typical noise reduction is 1.1 dba per foot of suppressor at 10-ft from the fan.

Noise suppressors are constructed with galvanized double-wall pipe, flanged ends for easy assembly, a galvanized weather cap and optional bird screen.

Call or email with the details of your fan model and location, and tell us what you’d like to achieve.
