Thread: dust extractor differences

The differences are basically the same as with any other machine - quality, warranty, brand.

A better quality machine will be quieter, run cooler, deal with longer running periods, filter better, last longer. The units under $400 are junk from what I've seen - but definitely better than nothing.

Obviously there are some differences in the basic metalwork, but the major cost differences come from the motors used.

Depends on your budget of course, but at least look at the Jet with cartridge filter - I love mine. I ditched my $400 odd 1hp for a $1000 2hp Jet and got much better filtration and a machine that I'm sure I'll be using 10 years from now at least.

Regardless of the the filtration capacity which is important, one of your primary concerns should be of the capacity of the machines you are using...in that if you intend buying a 1 hp unit then the total capacity or draw power(cfm cubic feet per minute)needs to be realised.
A typically 1hp unit may have a draw power of 400cfm provided it is dedicated to one machine as well as the hose diameter usually 100mm.
A 1 hp unit is ok for you if you have a means of isolating each machine you have connected..and this generally is by employing a blast gate at each point of isolation so that total suction is dedicated to the machine in use at the time.
Of course a 2hp which I use with 1300cfm does remove chips readily and therefore sawdust is also no problem.
I started out with a 1hp unit but progressed as my updated machinery and needs dictated.
There is no need to spend a lot of money but it does depend on your total requirements ..that is whether you would be happy with a 1hp of a 2hp which ducted,may meet any requirements should you decide in the future to upgrade to heavier use.
Just my views.
Cheers
