Combination Unit

Westech’s Most Versatile and Best-Selling Product

The Westech combination vacuum unit is our most popular and versatile piece of equipment. Designed with our customers input, this combi-vac truck unit built to provide similar service as a Hydrovac but with additional hauling capacity. More hauling capacity means increased revenue potential for the customer.

The combo vac truck has similar capabilities as the popular hydrovac design but without the heavy boom and associated hydraulics. Available in a number of customizable configurations, the most versatile units are designed as TC407 Hazardous waste hauling trucks. Also available non-coded.
