Solvent exhausting
Hello all,
I am about to move to a larger working area in my new house. I use a Mimaki CJV30 as a digital printer with SS21 ink (mild solvent). I did not care about solvent fumes up to know although I can’t stay in the room while printing (headache etc..). 😕
I plan to do things well in the new office. The printer will be in a room where I am not working on the computer and I plan to install something to exhaust solvent fumes.
I am wondering how you in your office do with solvent fumes. Do you have a special venting installation, DIY stuff, …? Please show me (with pictures if possible) how your office looks like.
I know Mimaki is selling an option which includes exhaust and drying unit together, not separately, I find it really expensive (~2000€ excl VAT) for what I need.
I was thinking about simply connect air pipes to the bottom of the printer (fixing holes are already available) but how to make an air flow to the outside?
Any advice would be very helpful.

The solvent fumes are heavier than air so tend to "drop" off the printed surface rather than rise into the air. We have installed a 300mm wall fan directly behind our CJV30 -130 at low level and when run at full power this copes with the extraction unless full flood coats of red are being printed.
Whatever extraction you use, remember to allow for the same amount of air to enter the room or the extraction will be ineffective. An open window will suffice but obviously not near the outlet of the fan.
Incidently, we have also just made our own drying unit for the CJV which now allows us to print and cut in one operation with a 15min delay built into the software. Total cost around £30 for our 12 fan unit which is a bit better than the £700 we were quoted for the drying unit!

thanks for your input.
Do you use SS21 or ES3 inks on your CJV30?
Would you like to post some pictures of your installation please? Just to have some example of how people manage to vent their room 😉
