Vacmasters Introduces Powerful Air Vac System

摘要

Vacmasters has introduced a new air vacuum excavation system model in the Vacmasters product line. It also is the largest commercially available air vacuum system on the market, said Trevor Connolly, Vacmasters vice president of marketing. Connolly said the System 6000 is the first air vacuum excavator with the power to trench as well as dig potholes. Compressed air for excavation is delivered through a proprietary air lance to penetrate, expand and displace all types of soil. A System 6000 can dig a 12- by 12-inch pothole to a 5-foot depth in three to five minutes, depending on soil conditions. "The primary benefit of excavating with high-pressure air is that large quantities of water are unnecessary, eliminating both the time required to continually replenish water supplies and the cost to transport and dispose of muddy spoils," said Connolly. "In addition, air will not damage underground utilities as high-pressure water can, making air excavation safer for operators and other crew members. Water is a non-compressible fluid that can cut or otherwise damage utilities. Water also is conductive, making it potentially dangerous when working around buried power lines or equipment. Also, air will not damage the road base and won't spread contamination plumes as water can do.
