    Can you describe more about your garage and the room above--how big, how are they built, are they insulated, how are they used, etc.? Have you looked into Lunos through-wall ventilators?

    the garage is about 1000 square feet i use it as a workshop and i do wood working so alot of polyurethane fumes etc. - have a mini split air conditioner but if i vent it with a fan it gets way to hot as its 120 outside. So its either im sweating or breathing in chemicals. So ideally i would want it vented sufficiently. Above it just an an unconditioned attic. I was ideally trying to get a decentralized ERV because i didnt see the point of installing an ERV just for one room with ductwork - but maybe that makes the most sense?

    If the fumes are as strong as you make it sound it seems like they will damage a EVR.

    Also, it seems likely VOCs are likely cross thru the heat exchanger of an ERV and contaminate the incoming air.

    They make equipment to deal with fumes it is called a pain booth if you must spray lacquer. Consider trying some of the modern water-based finishes.
