I recently purchased a Koala KP1200 blower to power my Kilgen. It works great!!! It is a bit noisy, but I built a silencing cabinet for it that works very well! It actually sits under the main windchest with the rest of the organ.

My plan utilized the “box within a box” design and is made from 3/4” MDF. The boxes share two common walls - the front and bottom - but are otherwise two independent boxes and walls are placed in specific ways (on the inside) so that the air must first travel the entire length of the back wall, then down the right side, up and over the inner box, down the other side and finally into the inner box through a hole that is opposite the side of the blowers intake and fan, making it a very long and curving path to deaden as much noise as possible. The interior is all lined with Auralex foam to kill the noise. I also used a FRAM automotive air filter for the intake. It weighs 80lbs or so but works GREAT! Check out the pictures.

All of the walls are screwed and glued in place to prevent leaking and seeping. So far the design works great - it kills all the noise and has a sufficient intake and output. If however, any of you have any suggestions or questions, please let me know. I'd love to hear what you think, particularly if I made any disastrous mistakes that should be addressed before I go any further with this venture. Also, if any of you have any similar designs, please share and compare!
