Thanks, Ashley Guardair Corporation Inside Sales Representative

what is the vacuume lift capacity and depth please?

I would say the length of the hose at least.

Does the drum have a drain port, and if so, what size and type of connection is it?

Good afternoon, There is a 2" hole towards the bottom. We do offer a liquid drain valve as well. https://guardair.com/products/liquid-drain-valve?_pos=3&_sid=7a43d4cd4&_ss=r
