The Studio Ventilation System

This is a general article on my installation, not a step by step how-to. You must adapt your setup to your particular situation and according to your homeowners association, local building code and budget.

I had several considerations to take into account when installing the ventilation system. I didn’t want to make large cutouts in the walls and didn’t want to get involved with the county building department with permits, etc.. Craig Milliron at Arrow Springs was kind enough to show me their classroom ventilation setup and Craig also directed me to Andrea Guarino-Slemmons web site that has a very helpful ventilation article.

This is what I built after studying several setups. Two identical systems; one for each torch on the bench. The fans, mufflers and blast gates were purchased on eBay for a good price. The switches, plugs, cement board, flex hose, etc. was purchased at one of the local big-box builder supply stores.

Ventilation
Torch ventilation on the side of the house.

I keep expecting the cops to stop by to see if I’m growing pot in my house because of the fans. I don’t have the front covers fully secured yet. The housings are made from a type of cement board. It is not flammable, water doesn’t degrade it and it can be painted to match the house.

Mounting the fans.

The fans and mufflers are the ones recommended on Andrea Guarino-Slemmons web site listed above.

Vent window feed-through with 6″ blast gate.

The blast gate is closed to keep cold air from blowing in from outside while the fan is off. Open it for fan operation. There are locks on the window track to keep bad guys from lifting the window off of the window insert and entering through the open window.

CGFI switch to plug the fan into.

The electrical cord is connected to the fan and plugs into the CGFI extension cord switch to avoid electrical permit hard wiring. The rocker switch above the plug turns the fan on.

This setup works extremely well for us. No gas combustion odors in the studio. Both vents are also next to the kiln so it helps remove the escaped heat and keeps the studio a little cooler.
