50AE Posted August 14, 2022 Share Posted August 14, 2022 Hi folks,It's about an indoors drying box for varnish impregnated coils for transformers. You see, my workplace is still where I live and I need to find a way to make it odorless as possible. I thought about getting some of these indoor growth chambers with active carbon filter. The varnish is I think alkyd based air drying type. It dissolves some types of plastics and glues, so I need to take this into consideration.

Richtee Posted August 14, 2022 Share Posted August 14, 2022 (edited) Well... vent it outside. A small fan and some (metal) dryer vent tube. Edited August 14, 2022 by Richtee Link to comment Share on other sites More sharing options...
50AE Posted August 14, 2022 Author Share Posted August 14, 2022 Yes, it's probably the best idea. There's the kitchen chimney, I could install a T fitting for an additional pipe leading to the drying box. Link to comment Share on other sites More sharing options...

There's the kitchen chimney, I could install a T fitting for an additional pipe leading to the drying box.I guess I don’t know what is vented by that chimney, but of course be aware of the flammable nature of the box’s fumes when cooking. You venting a wood fired stove or anything like that? That would be an issue. Link to comment Share on other sites More sharing options...
50AE Posted August 15, 2022 Author Share Posted August 15, 2022 I rarely cook, no problem taking this into consideration. Link to comment Share on other sites More sharing options...
Richtee Posted August 15, 2022 Share Posted August 15, 2022 I rarely cook, no problem taking this into consideration. I cook quite a bit, so it popped into my head. ALSO..be aware of possible “backdraft” into the oven/stove. Give a sniff before you DO fire it up, just in case some fumes migrated that way. Outside wind COULD cause this.

50AE Posted August 16, 2022 Author Share Posted August 16, 2022 I use the stove mainly for production purposes, including waxing coils. No more than 130 deg C Link to comment Share on other sites More sharing options...
Scotty123 Posted August 24, 2022 Share Posted August 24, 2022 (edited) Re exhaust filtering: at one point I bought a box of activated carbon pellets, IIRC they were inexpensive; wondering about DIY exhaust filtering using such materials. Thinking of applying it to laser cutter exhaust, where you need to filter a lot of burnt wood, plastic, etc.For any pyro use, better keep sparks out of it!

Mumbles Posted August 30, 2022 Share Posted August 30, 2022 Charcoal is pretty good at removing odors and absorbing organics. I will caution that when actively absorbing organic solvent vapor vs. just deodorizing something, they will probably saturate faster than you think.

Arthur Posted August 31, 2022 Share Posted August 31, 2022 Can you use a retired microwave oven? Disable the transformer and magnetron and just use the fan and a suitable duct. Link to comment Share on other sites More sharing options...
