An air scrubber is one of the most advanced and important tools a water damage restoration professional can have in their collection of equipment. An air scrubber requires regular maintenance to perform at its peak.The addition of the DOP filter makes the RA-650 a high efficiency three-stage air filtration unit, ready for any sensitive job requiring first-pass HEPA filtration. With the standard pre-filter, DOP Stage 2 pre-filter and the HEPA primary filter installed, the RA-650 passes laboratory DOP testing conducted per ANSI standards, achieving an efficiency rating of 99.97% against oily aerosol particles down to 0.3 microns.

• Passes laboratory DOP testing when installed as part of 3-stage filtration process
• Equips the RA-650 for a wide range of environments that require first-pass high efficiency air filtration
• Achieves an efficiency rating of 99.97% against oily aerosol particles down to 0.3 microns
• The addition of the DOP filter makes the RA-650 a high efficiency 3-stage air filtration unit, ready for any sensitive job requiring first-pass HEPA filtration

Activated Carbon Filter upgrade boosts RA-650 functionality HEPA filtration is increasingly seen as the single most important safety device available for creating a safe environment for jobsite workers. Now, with the Activated Carbon Filter, the RA-650 can play an even more important role in keeping an enclosed environment clean and safe - both for workers and for occupants. The activated carbon filter now equips the RA-650 to capture a wide variety of volatile organic compounds (VOCs), including soot and smoke, food odors, fumes from paint and paint thinners, sewer odors and many other compounds. No modification of the RA-650 is required - users simply place the new carbon filter inside the cabinet in front of HEPA filter and then re-secure the cover. Capacity of the carbon filter will vary widely depending on conditions, but it should be replaced when a decline of effectiveness is noted.

• Captures a wide variety of volatile organic compounds (VOCs)
• Utilizes extruded activated carbon - carbon pellets manufactured to uniform size helps to ensure maximum airflow and maximum contact
• Works by adsorption, carbon filtrations natural ability to attract and hold gas and liquid molecules on its surface
• 1 lb. of carbon has 534,438 sq. yds. of available surface - equivalent to the area covered by more than 100 football fields
