Super nice and well-cared for Hi-Vacuum pump that works great. All cast iron belt-driven pump, comes with Teflon core/braided stainless steel line that is about 8-10 feet long. Cord has on-off switch. There is a 0.2 micron exhaust filter. Gage was a fluid-filled type (so that vibrations were averaged out) but the gage is sprung.
