do you guys use oil compressors to power the pumps, or any other (oil-free?)

Thanks!
Regarding detector I had something like this in mind: https://en.safetygas.com/gas-organic-vapor-detector-pac-8000-ov
Tanks and pumps grounded. Pump will be a double diaphragm pump with Atex certification. I plan to mix in the sugars with hdpe stirring paddle. 

My first post here 👋
I'm putting together an equipment list for my small batch liqueur "distillery." I have read and learned as much as possible about Atex equipment and handling high-proof neutral alcohol, both here on ADI forums and elsewhere.

I plan to macerate in 200L tanks, and the question is which to choose - variable capacity tanks with air-sealed lids or closed tanks (images attached). The way I see it, the variable ones are easier to macerate in (bigger opening at the top, easier to clean), while the closed ones appear to be used more for high-proof alcohol (safer?). I will macerate some botanicals at 90% for a day or two, but most at around 60%.
When considering a filtering system, at first, I thought about plate filters, but I just found out about cartridge filter housing which I guess is much safer (and better?) way to filter?
One last thing: Do any of you use vapor detectors while working with high-proof alcohol?

Experiences and recommendations appreciated!
