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 And unlike outdated wet scrubbers that require constant upkeep and handling of caustic solutions, the Sentry™ is safe, reliable and dependable.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.

UL’s Highest Rating

Unlike our competitor’s charcoal-based media, PureAir Filtration’s Sentry™ with Safetysorb adsorbent media is alumina-based so it is fireproof, earning it Underwriter Laboratory’s coveted ‘Class 1’ rating.

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.

North Texas Municipal Water District case study brochure
FACILITY TYPE: Municipal Water Treatment Facility

LOCATION: North Texas

EQUIPMENT/MEDIA USED: Emergency Gas Scrubber (EGS-300) and Safetysorb adsorbent media

PROBLEM: The water treatment facility stores more than 300 pounds of chlorine onsite and needed a solution in the event of a leak

SOLUTION: PureAir’s EGS-300 kicked into gear when one of their dry scrubbers had a leak, pulling the toxic gas from the air and through the scrubber where Safetysorb absorbent media neutralized it, releasing only purified, clean air into the building. According to the Instrumentation Technician working the night of the leak, “your system is working very well. It was dealing with the chlorine leak before our main system detected the leak.”
