Vacuum Excavators

Vacuum Excavation, also known as “Potholing” or “Daylighting” is the process of using vacuum and sometimes an assisting process such as high pressure water jetting and high velocity air jetting to “suck” a hole in the ground. The hole size can be from 4 to 12 inches in diameter and can be from 1 to 20 feet deep. This process replaces manual or machine digging when there is the possibility of damage to anything in the underground vicinity of the area being uncovered.

These units are offered as a skid mounted vacuum or can be built onto a flatbed or trailer. Pacific Tek offers eight basic tank sizes with over 100 different configurations and options, depending on the customer’s needs. The larger tanks have a reverse flow option where, at the flip of a lever, flow is reversed in the system which allows you to either pump liquid or slurry out of the tank to a higher place, or, to free up clogging in the pickup hose by having air blow the reverse direction.
