Ventilation: Will this work?

[jaylee78]

Ok, I'm completely clueless when it comes to all this ventilation stuff, but wondered if this would work?

If you are lookng for a one size fits all GLASS ventilation solution, no this probably would not do....

About the closest thing to a out of the box vent system is the GLASSCRAFT hood and it has some issues as it come from factory...

Not trying to be a pain, just curious as to why it won't work as well. kind of helps me figure out what I need to be looking for . . .

If you are going to use it for a glass kiln, don't bother. A "glass annealer" in almost all cases really does not need a vent hood except to maybe remove excess heat. and a small fan will do that. As for a work station hood the round hood design makes it to complicated to control air flow to be sure the proper amount of fresh air is deliver into glass workers breathing zone... Also flexible ducting is probably worst type of duct work you could use for ventilation it is to restrictive to air flow.

You need to design your ventilation, by figuring hood size, developing air flow calculations to get sufficient volume of air movement and control where your contaminated air is exhausted and in what relationship it is to your make up fresh air.

You need to register on site to see graphics.

Basically you need a hood like a small restaurant hood or stove hood, maybe 18X 24 inches square opening or make a fume hood like used research laboratories, which will have a face opening of about 3 square feet, the you will need at least a 300 cfm blower to maintain a 100 cfm face velocity air flow. and you will need to duct this out of studio in shortest possible route using as few turns as possible. Also duct diameter should be at least 8 inches.

This is all been discussed on may sites and all the sizes and formulas pretty well proven and most problems have been worked out...

You need to do the research and be informed before making any selection in this area...

Thank you Dale, this was what I was wanting to know!
