Hydro Excavator

The GapVax Hydro Excavator is the world's most advanced industrial vacuum truck. From Texas to Canada, and everywhere in between, the GapVax Hydro Excavator is the do-it-all truck for every job. Our wet-dry, cyclone-based filtration system allows you to vacuum both wet and dry materials, and our hydro excavation system brings the power of water to the power of air moving. Whether you're a hydro excavation specialist or a industrial service generalist, this is the best hydro excavator on the market. We've put over 37 years of experience in the industrial service industry into every detail of this truck to make it the longest-lasting, lowest-cost-of-operating hydro vacuum excavator on the market.

GapVax vacuum trucks are renowned for their highly efficient filtration, low baghouse maintenance costs, and long filter-bag service life. With proper service, a GapVax truck can normally operate 1,500 to 2,000 hours before requiring a change of filter bags. Since filtration/blower maintenance is the single greatest expense of a wet/dry vacuum truck, superior filtration immediately lowers operating costs. Another benefit of the GapVax filtration system is more efficient loading and lower fuel consumption costs because clogged filter bags slow down loading and can cause excessive fuel consumption. Lastly, GapVax filtration is single mode, meaning there is no changeover required to go from wet mode to dry mode.

Simply put, the best filtration is the filtration that reduces dry carryover into the baghouse (and completely eliminates wet carryover). On a GapVax, many design elements work together to acheive this result. The whole truck was designed from the ground up to minimize carryover into the baghouse. Let's take a look at how that works:

No truck on the market today filters dry material as efficiently as a GapVax. The combined function of top loading, the baffle plate, the long tank, and cyclones prove unmatched filtration performance. Our proven design originated in power plant service vacuuming fly ash. Today, the GapVax provides excellent service in the widest operational envelope for wet and dry applications, while keeping filter and blower maintenance costs to a minimum.
