Dust Collection: Snap-lock Ducting

Snap-lock ducting offers a great compromise between affordability, durability, and ease of install.  Fittings and adapters are easy to find locally and online. The only tools needed are a HVAC crimping tool and an offset tin shear.  I purchased both for less than $25.

I am using Gripple’s Hang-Fast system.  It makes hanging your ductwork a breeze.  Simply, hang the loop on an eye-bolt or j-hook.  Then, slide one end of your wire through the grip.  Loop the wire around and insert it through the other end.  It’s self-locking and can be loosened using a supplied key.  I am very happy with this product and would use it again in a heart-beat.

The straight pipe goes together easy enough.  Cut the pipe to length using a pair of offset shears.  Then, snap the seam together by starting at one end and working down towards the other.  Once snapped together, it helps to drive a self-tapping sheet-metal screw near each end.  You could also use pop rivets.  Finish each section by crimping one end.  The crimped ends should always point back towards the collector.

I secured each section and fitting using a couple of sheet metal screws and then sealed all the seams with clear silicon caulk.

I’m currently about two-thirds of the way complete with my ducting.  Even with ample planning, it’s hard to know exactly what you’ll need until after you get started.  I am short a few fittings and patiently wait for them to arrive.

Stay tuned.

Dust Collection: Installing the Super Dust Gorilla

Good dust collection is a productivity saver.  Good fine dust collection is a lung saver.  That’s why I invested money into a powerful dust collector with pre-separation.

I did a lot of research and decided on the Super Dust Gorilla from Oneida Air.  It has a powerful 3hp motor, cyclone separator, and HEPA filter (filters 99.97% of .3-.5 micron particles).

I have nothing but good things to say about the great people at Oneida Air.  They were fair and very helpful.  Their product is extremely well made and made entirely in the USA.

Bracket and Cone-web

I opted for the wall bracket.  Initially, I attached the bracket to two studs.  I was a concerned about durability so, I tied in two more studs using 2×6 cross-braces.  This feels much more secure.

Then, I assembled the barrel to the fan housing, and the motor to the fan housing.  The top half of the assembly weighs well over 100 lbs.  Attaching it to the cone on the bracket was not easy for two able men.  Do not attempt this by yourself.

Then, I simply attached the filter using the supplied hardware.  I replaced the supplied plug with a L6-30 twist lock.  I had an issue with the bolts used to connect the filter plenum to the fan housing.  They were too short.  This is due to the gasket material used between parts.  They might have worked if I had clamped down the flange to compress the gasket.  Instead, I went out and spent a few bucks on longer screws.

I did a quick fire with everything attached using the optional remote control.  Everything works flawlessly.  I can’t believe how much air this thing pulls.  I’m looking forward to a dust free work area.  I just need to get the ductwork installed.
