Thread: Anyone have any thoughts on the OBM grinder?

If the fan spins backwards, just install it backwards....

Grinding steel goes everywhere. When I was in the finishing department for a way cover manufavturer, we would have the days between Christmas and new years to clean. On top of lights, fans, etc.

Reconsider any "long" duct work or many elbows, this increases the load on any systems. This is called "head pressure" in fluids texts. Any filter should be fine, but a cheapo car or home filter is easily replaceable.
