getting my HVAC parts for the Thien Baffle project. I originally was going to relocate the blower from being vertical on it’s Grizzly stand to horizontal above the Thein Baffle chamber. I “thought” the outlet arms to the 2 filter bags were joined by square joints, but they are rectangular. Which means, since i rotate the motor 90 degrees from vertical to horizontal, so too are the outlet arms, so too would the bags.. which means I would have to rotate the bags back to vertical.. but the rectangular unions will not match up anymore. Grrrr….So now the idea is to keep the Grizzly on the floor where it is.
Thought about 7” round flex.. but WOW. $120+ for 10’. I looked around to see how other’s connected their separator to dust collector. I see lots of flex hoses 4”-7” popping out vertical and a direct beeline to the dust collector down at floor level, incurring 2 very sharp 90 degree bends, which I thought was a no no ?
My possible solution is to install 2 7” 90 degree adjustable elbows for the top bend, followed by 3 or 4 feet of straight 7” duct, then a single 7” 90 degree adjustable elbow into the impeller fan. I called my local HVAC supplier and the 7” adjustable 90 degree elbows are $3 a piece. These elbows have a more gracious bend to them, are not corrugated, total price would be $20 instead of $100+, oh… and this will allow me to put in a 7”x 7” x 7” wye in case I wanted a branch to vent outside in warm weather and a branch to the filter bags/canisters.
I know any adjustable elbows will leak so I am prepared with lots of HVAC sealing tape :)
