The 1HP DCs are just not going to cut the mustard.
The 2HP DCs in stock form using 100mm ducting will appear to catch most of the dust but what they will not do is capture the fine (ie most significant in terms of health) dust, made by these machines. You won't even see this fine dust so cannot tell by looking if it's being captured.
Things to consider;
1) Do you want to capture the majority of the fine dust using only the DC the DC - if so
- The 2HP DC will need to be modified to utilise 6" ducting using the method described in the Sticky Thread at the top of the dust forum.
- Then 6" ducting and flexy will be needed
- The machine dust ports will need to be opened up to about 6" or equivalent to allow enough air through the machine to seep up the dust
- Leaving you DC inside the shed is not a good idea as they leak fine like sieves, especially those towed around inside sheds. To avoid this problem the Dc should be located, or enclosed in an air tight cupboard, and vented outside the shed.
- Yes, it's a bigger than "Ben Hur" undertaking, and I'm sure you're very pleased to hear this.
