This unit connects to a central vacuum system via standard quick connector. Millimeters of HG are in increments of 2mm. The amount of potential vacuum delivered through this device can be set at the wall connector via a ball valve as well as controlled by a knob (blk/yellow) used to control the amount of suction being delivered. There is a lock to control suction in front of the main adjuster knob. The 2.5 inch gauge can be pivoted and secured in place to allow for optimal viewing. It's clear plastic pop off lens has some light scratching, but nothing that obscures the view. The overall condition of this unit appears to be good.
This is the only one of these I have run across. There is no manufacturers ID or model information on it. It appears to be a more robust version of what the standard plastic Allied and Ohmed vacuum regulators equipped with quick connects do (I have these listed as well). It is priced as it is because of the absence of comparable products, more than anything else. If you know what this is, you know it probably has replacement value 8 to 10 times the listed price.
