J. Phil Thien's Projects

Just curious .... isn't the dust from the filter just falling down through the cone and landing on the thien baffel ☺☺.. :)

I have attached a sketch of my idea for the top hat .... it is massive i know but the barrel is 600mm in diameter ... the top hat rougly the same

Data is about max 50 cfm at 0,4 bar normal condition ... and tripple cfm at turbo mode

The point is the blower is there to deliver enough volume to make airspeed in a 3inch hose move at around 7feet per second at various pressure due to length and height of hose for ceiling insulation .. for walls its constant pressure and various pressure dependig on blowertip size .... and the air for the blower is being sucked from the feeding chamber through the baffel/filter to keep dust from escaping the machine

I can live with about 0.15 bar max vacuum at the intake side without losing too much pressure on the output of the blower ... which means i could use that to hopefully get even better fine dust seperation and perhaps not clog the filter to much to quickly

I've been tempted to try it w/ my shop-vac based system but prefer having the bag in the shop vac act as the first line of defense.  No matter how good a separator you have, some always gets by and the vac bag (in my case) catches almost all of it and the final filter stays more-or-less clean.

I'd like the filter/protection inside the tophat to save space at the blower placement ... its tight enough there already :)

The suction is a 10 hp high performance  side channel blower  ... mainly because i need the high pressure and air flow to move paperinsulation  ... max airflow is 600m3 pr hour  and max vacuum is 0.45 bar

Has anyone tried making a top hat and placing a cylindrical filter as center suction ... i plan on trying it because i need the filter to protect the blower assembly from overflow ... but i also would like the extraction of particles to the bin for convinience

Plan is as follows:
Top hat cyclone 12 inches high 15 inches diameter with 4"round inlet gradually transitioning goind half way round to a thin slit about half inch ... the seperator slot would be 1 inch ... and the automotive filter i got is same height and outer diameter is 6,5 inches

Hello im a carpenter from denmark ... saw the Thien baffle concept by chance on youtube and now i bulit my own ... and already modified a few things .. i'll post pictures a a video later ;)
