WANTED -> I need a renerative blower

[JeffW]

Worm harvester I made..[attachment=0:3lqvo0wz]g.jpg[/attachment:3lqvo0wz] First pic is view of outside rain water tank (both are 250G totes) I can transfer water as need from this to the inside tank and make tea. Next pic is the top of TEA tank, it needs clean up and minor adjustments. Need to finish mounting air lines and set up "basket" which holds castings/compost as it is being brewed. That will be easy to do once I figure out where and type of screen, needs to be easy to clean and easy to setup so I am thinking about it.[attachment=1:3lqvo0wz]f.jpg[/attachment:3lqvo0wz][attachment=2:3lqvo0wz]d.jpg[/attachment:3lqvo0wz]

The blower needs some type of AIR filter AND can i clean this thing? I do not want to open it and discover I messed it up so any advice on that I will adhere to.
