difalkner Posted April 22, 2018 Report Share Posted April 22, 2018 This window mounted fan support is a long overdue shop upgrade project. Every time I spray lacquer I had to rig the fan to stay in the window (it fell once and bent the blades). And it didn't work very well, either. As much air came in the window as the fan blew out. Also, every bug that got near the window got sucked in by the vortex on the periphery of the fan. This is much, much better! Enjoy!

lew Posted April 22, 2018 Report Share Posted April 22, 2018 That's pretty neat! I used a furnace blower motor mounted in the window. My shop is in the basement so I just removed the basement fold in window and replaced it with the blower and added some filters to keep the dirt/dust from clogging the motor. difalkner and HARO50 2 Quote Link to comment Share on other sites More sharing options...

Wil Posted April 22, 2018 Report Share Posted April 22, 2018 Not certain, but thought this was frowned upon due to the extremely flammable fumes passing thru an electric motor that could generate a spark to ignite the fumes.

Wil Posted April 22, 2018 Report Share Posted April 22, 2018 (edited) Yeah, hopefully the gas can is used for something other than gas if it's in the wood shop. I worked in a body shop in high school and the spray booth exhaust had to have the fan or blower removed from the duct. The fan itself could be in the duct but turned via a pulley setup so the motor was isolated. Maybe I'm wrong, but would highly encourage someone to do some homework before doing this.

They work great EXCEPT in a basement shop where the furnace is located in the same room. The fan creates enough airflow that it can suck furnace fumes DOWN the chimney. Don't ask how I know this!

Don't ask how I know this! the furnace box should be sealed and have make up air.. okay... itty bitty TEFC motor to turn a small squirrel cage.. it's the type of motor that is the issue...

A commercial set-up would require XP motor, OTOH commercial wouldn't use a prop fan. Quote Link to comment Share on other sites More sharing options...

Wil Posted April 22, 2018 Report Share Posted April 22, 2018 Great comments. Think the moral of the story is to really think this through before putting this solution in place. You may not got the chance to reevaluate this. Stick486 1 Quote Link to comment Share on other sites More sharing options...
difalkner Posted April 22, 2018 Author Report Share Posted April 22, 2018 Thanks guys, but I have thought this through and have been putting that fan in the window for the last 18 months. I just now decided to mount it so I don't have to jump through hoops to keep the fan on the window sill and to increase air flow. I realize it isn't explosion proof but when I spray it isn't very heavy and with the HVLP gun there's so little overspray and airborne material that it's gone in no time. Now if I was using a cup gun and filling the room with a cloud of vapors that would be a different story but I spray small items and it's over with pretty quickly. There's another window and it's open to bring in fresh air. Yes, the gas can has gas in it like millions of other guys have in their garages for their lawn equipment. I put the mower out on the back porch but if I put the gas can out there the plastic won't last and the gas will likely evaporate. It's a wood shop, no metal work, no open flames anywhere near the gas can that's been there going on 11 years. Is this ideal? Nope. But we don't have the budget or the space to build a dedicated wood shop out back or even a shed to put the lawn equipment and gas can in so this is going to have to do.

difalkner Posted April 22, 2018 Author Report Share Posted April 22, 2018 (edited) Thanks for your concerns, Stick. David Edit - I added a disclaimer to the description ***Disclaimer*** This is not an explosion proof fan. If you're wanting to build a similar stand for your shop you should probably look into an explosion proof fan or other setups to prevent fire and explosions Edited April 22, 2018 by difalkner Stick486 1 Quote Link to comment Share on other sites More sharing options...

It's possible that I could get there if I had a spill. And the possibility of a spill is not so remote as to render it inconsequential. accidents happen.

Stick486 Posted April 27, 2018 Report Share Posted April 27, 2018 you know the best way to ventilate for hazardous fumes is to bring fresh air in and elevate the room to positive pressure... and yes, a spill comes under the ''what if'' category.. schnewj 1 Quote Link to comment Share on other sites More sharing options...
PostalTom Posted April 27, 2018 Report Share Posted April 27, 2018 Two thoughts: 1. Everything is OK until something happens to prove it actually wasn't. 2. That said, has anyone actually heard of a situation (in a home shop, I'm not talking about OSHA controlled industries) where an explosion really happened due to this kind of set-up? This may be similar to the static grounding discussion in dust collection systems to prevent explosions, which I am convinced are only needed as a comfort factor.

PostalTom Posted April 27, 2018 Report Share Posted April 27, 2018 OK Stick. I had a similar experience with static coming through the antenna in a headphone radio. Not to be confused with radio headphones. I had to explain the difference to a Best Buy clerk. The static didn't cause any pain such as you described, but it did reset all my stations back to factory settings, so I can see the possibility of what happened to your friend Ray. I stand (or in this case sit) corrected. Quote Link to comment Share on other sites More sharing options...
