Ensure Water Quality and Safety with AST-Vent
Without a doubt, our water supply is our most precious commodity. And you are entrusted to protect it from several factors, including:

Humans: terrorism, sabotage and interference

Nature: birds, insects and foreign objects

Environment: freezing temperatures and rain

Now you can sleep better knowing you have help from the AST-Vent (Always Safe Tank), a fail-safe means to protect our valued water supplies and your reputation.

While the threat of human sabotage is real, it is limited. Yet the daily challenge to protect tanks from natural and environmental factors is critical. Don’t think so? Just ask someone who had a tank explode or implode because of improper vapor release or faulty vacuuming.

Fail-Safe
The fail-safe AST-Vent will protect your precious water supply from humans, nature and our ever-changing environment. The vent allows air and vapors to flow properly, minimizing excessive pressure or vacuum in the tank. The proprietary design allows proper air movement at all times, even when the protective screen becomes frosted over or blocked by insects. Should these conditions occur, a pressure or vacuum pallet will lift to relieve the excess forces. When the air flow is restored, the pallet returns to its original position. And the unique lockable design makes the vent secure to deter any efforts to sabotage, corrupt or vandalize your water supplies.

Professionally Built. AWWA-Compliant.
The AWWA-compliant D100-05 aluminum construction, also available in stainless steel, ensures a lightweight, non-corrosive and low maintenance vent. The vent was designed by a 35-year veteran of the water industry and continues to be manufactured by Advance Tank Construction, a leading and trusted water tank fabricator. Proven to withstand all kinds of environmental extremes, from hot desert conditions to the frozen rigors of the Antarctic, the AST-Vent is built to last and give you the peace of mind you need that your water supply will remain safe.
