    Exhaust options for garage roasting

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I am used to roasting inside on the hottop with the rangehood running, however I have now setup a workbench in the garage and would like to start roasting in there.

    Looking for ideas and suggestions around the best way to exhaust all the exhaust out. The garage walls are brick and would be difficult to install an exhaust fan.

    My thinking was to have an overhead exhaust fan above the hottop and have it duct outside using flexible hosing. This option though wouldn't be permanent and would require opening the door to the backyard open and manually locate the duct to exhaust outside each time I roast. So something like this: https://www.bunnings.com.au/ixl-170m...-duct_p4449333

    I've also seen activated carbon fans that are more directed to soldering but don't think that will do a good enough job.

    Put a rangehood in.... Often come with the vent pipe and the wall vent can be bought from bunnings. If it works ok in the kitchen, it should be ok in the shed... I picked one up recently on junk day, bit greasy, but it should clean up ok. Aldi has them for cheap I think I saw in latest catalogue...

    Any ideas how the vent pipes could work in the garage ?

    yes- some basic handyman skills and common sense are required though

    Just leave the garage door open, the smoke clears very quickly, a $10 pedestal fan from Target, strategically placed will help it dissipate.

    Yes, put the rangehood above where you don't want the smoke, put the vent where you want the smoke, join the 2 spots with vent pipe. Remove bricks where required...

    Probably yeltas fan and a open garage would suffice for at least a test run

    I thought Aldi had the best supermarket fans?

    I'm sure common sense is a given.

    I was asking in the context of the OP's comment that an exhaust fan was hard to install due to the brick wall.

    I've been using this method for years, my Coretto is positioned near the door with the fan positioned to blow the fumes outside, works fine, not a trace of roasting fumes or smoke when finished.

    A SDS drill with a selection of bits and drills will remove bricks and half bricks very easily (and messily). Mark out where you want the hole (check for services behind), drill along the marked holes, then change to chisel tip to remove what's left.

    Think I'll be going with this too while building my corretto next.

    Will take a look and see how much room it takes up, at the moment I'm roasting on top of a workbench that has shelves on top which restricts the height of what I can install above the roaster.

    I currently have a fan and last I roasted I had the garage door opened and the back door opened, though there wasn't enough air flow to vent the garage out. Will try some more powerful fans to get more circulation going as that is probably the cheaper options so far.

    A bit of range hood flex works for me, carries the chaff and smoke out the open door, with a small fan assisting in direction.

    You can also get small inline fans to mount in the flex to draw air out. eBay has them, marketed for venting grow tents, not sure what level of heat they will take.
