Thread: Dust extractors

Hi Richard,

I have the Carbatec model. Other than “it does what it’s supposed to do”, I don’t know what else I can tell you. If you have anything specific you’d like to know, I can answer any queries (or try to ;-) ).

At $500’ish, I’d make the same purchase again. I purchased the Carbatec model as they are local to me, so saved on freight.

Thanks - Just like to get a second opinion before I make a capital purchase

I haven't had a look at DC's in a while but my advice is take a look at both machines and their specs carefully as I've always found Carbatec and Sherwood are direct competitors but at the same time don't compete with each other. What I mean by this is both machines are built to their unique specifications and therefore price point and even though they look the same they are different. eg different motors, thinner filters, dust bags, even power cord lengths etc.

So have a think about what is important to you and go inspect both machines to see if they meet those requirements.

The manufacturers air flow specs on DCs are somewhat meaningless. If they have been tested at all then they are usually done to an Australian standard procedure that know for a long time to be incorrect and have little relevance to when used in a real application..
My experience is in real world situations you can basically halve the manufacturers flow rates and some are even more exaggerated than that.
If a 3+ HP DC is used with 6" ducting then the limitations is rarely the DC but the size of ducting uses. Most of these DCs will pull close to the maximum amount of air possible through that size ducting and the size and length of the ducting and the size of the ports on machinery tend to be the flow limiting factors.

Agreed, what I meant was physically inspect the machines in person and look at the motor, impellor size, quality of filter bags, dimensions of inlet/outlet etc

Indeed all good things to check.

The most important technical spec that DC suppliers could provide is the impeller curve (Flow versus Pressure Loss) but given they don't even measure the max flow correctly I guess we can't expect to see these.
