Why the Sentry™?

Sentry logoIn case of a leak, the Sentry™ springs into action, capturing escaping chlorine gas before it puts unsuspecting employees and citizens at risk. And unlike outdated wet scrubbers that require constant upkeep and handling of caustic solutions, the Sentry™ is safe, reliable and dependable.

PureAir Filtration’s Sentry™ offers a one year free warranty on materials, a low cost 10 year extended warranty and free annual lab testing of its gas adsorbent media. Installation can take as little as three days and systems can be customized to meet your needs.

Guards Against Leaks: Improves EPA Risk Management Rating

In case of a toxic chlorine leak, you can’t afford to be without the protection of a Sentry™ with Safetysorb. A sudden leak can endanger lives and result in serious legal issues.

City of New Buffalo water treatment case study brochure
In late 2011, The City of New Buffalo, Michigan, completed an expansion and upgrades to their existing 40-year-old Water Treatment Plant.

Part of these upgrades included the addition of a third filter building to handle one million gallons per day, and with that, the requirement to add chlorine gas scrubbers to be on standby in the event of an emergency. PureAir’s Sentry™ Emergency Gas Scrubber and Safetysorb adsorbent media were chosen for the job.

A few years later, the municipality found itself in the terrifying situation of a leak, and all were relieved that the Sentry™ EGS was onsite.
