Do I really need an extractor this large?

[Albert Lee]

I have a SCM sander that I need to hook up to the extraction system.

the machine manual states the following for the main suction and the blower() unit

327694

327695

4040m3/hr + 2280m3/hr= 6330m3/hr = 3720CFM at 2313Pa

3720CFM at 2300Pa is a lot for a 4~5.5hp extractor. My current extractor is a 5.5hp extractor. I have a feeling it wont do a proper job.

I guess I may have to buy a smaller dust extractor for the oscillating blower unit and place it right next to the sander just servicing the oscillating blower.

Or just upgrade to a larger 7.5hp or 10hp hp extrator?

Try what you have and let experience guide you not numbers on paper.

Is that a 43" single or double head? The double head needs at least a 7.5 hp bagger with oversize bags. dave
