Woodwaste Extraction System

Woodwaste Extraction System

Woodwaste Extraction System

Having been on the BIOH M303 Testing of LEV systems course, I was quoted 10-15m/s duct velocities for medium density dusts however, other publications state 15m/s as what I presume is a minimum.

Could anyone clarify the exact figure as when advising someone I need to be exact and not appear vague


RE: Woodwaste Extraction System

I would defer to the Manual of Industrial Ventilation by American Conference of Governmental Hygenists.

RE: Woodwaste Extraction System

The number I have for Air Velocities for Pneumatic Converying are:

4000 fpm, Wood Dust
3800 fpm, Dry Sawdust
4500 fpm, Wet Sawdust
4200 fpm, Metal Dust
5000 fpm, Aluminum Dust
7000 fpm, Cement Dust
4500 fpm, Foundry Dust

fpm = feet per minute

What kind of dust are you conveying?
