With only one moving part, the Sentry™ is safer and more reliable than old fashioned wet scrubber systems, requires less maintenance, is easier to operate, and costs less. If you currently have a wet scrubber system in place, call us today. Your current system may qualify for our trade in program.

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 And unlike outdated wet scrubbers that require constant upkeep and handling of caustic solutions, the Sentry™ is safe, reliable and dependable.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