Carbon scrubbers absorb carbon dioxide (CO2) and help to contain nuisance and harmful odors and exhaust gases. General Aire offers a variety of carbon scrubbers to meet the needs of your facility.
Carbon Scrubber Products
Purafil® Deep Bed Scrubber Purafil® ESD Drum Scrubber- 500 Purafil® Positive Pressurization Unit (PPU) Camfil ProCarb HBD Camfil ProCarb VDBE
Purafil® Deep Bed Scrubber
The Purafil® Deep Bed Scrubber (BDS) is designed for areas where high contaminant gas levels are present. It provides protection against environmentally induced corrosion in control and switchgear rooms equipped with electronic process control systems. The DBS is ideal for refineries, steel mills, smelters, chemical plants, petrochemical plants, and other hostile environments.
Each DBS is designed to deliver “G1” air to the space it is protecting according to the environmental standard definition set by the Instrumentation, Systems and Automation Society (ISA).
Read MoreFeatures and Benefits
- Provides “G1” corrosion-free air to the space it is protecting. The scrubber’s aluminum corrosion is corrosion resistant and capable of withstanding outdoor conditions.
- To control specific contaminant gases, the DBS is filled with up to three different dry scrubbing media manufactured by Purafil, Inc. Each media type effectively removes a range of contaminant gases for maximum protection against corrosion.
- Effective at a low cost per CFM.
- Designed to be compatible with the Purafil Corrosive-Air System (CA) and the Purafil Side Access System (PSA) when room requirements include environmental recirculation.
Purafil® ESD Drum Scrubber- 500
The Drum Scrubber–500 (DS-500) is ideal for removal of odorous gases found at pump stations, lift stations, wet wells, force mains, and even at the wastewater treatment plant. Recommended for moderate-load applications, the DS-500 is sized for airflows up to 500 cfm.
At the core of ESD’s high-efficiency odor control systems are dry-chemical air filtration medias. The DS-500 is bulk filled with multiple layers of Odoroxidant™, Odorcarb™ II, and Odormix™ media for broad-spectrum removal of sewage odors at 99.5+% efficiencies.
Read MoreFeatures and Benefits
- Constructed of corrosion-resistant materials and requires essentially no maintenance, making it ideal for remote, outdoor applications or areas where high levels of acid gases are present.
- Low maintenance
- Designed for quiet operation in residential neighborhoods.
- Two media sampling ports, located on the side of the DS-500, allow for easy access to the media beds.
- System media are UL Classified Class 1 and 2.
- Spend media is landfill disposable.
- Maintains superior performance in climates with fluctuating temperature and relative humidity.
Purafil® Positive Pressurization Unit (PPU)
The Purafil Positive Pressurization Unit (PPU) is a self-contained, air cleaning system, designed to provide pressurization air, free of corrosive gases. The PPU is recommended for controlled environments containing sensitive computer electronics and electrical equipment. Designed to stand alone, it can also be used in conjunction with Purafil’s Corrosive-Air System when recirculation is also required. Key application areas for the PPU are computer rooms, control rooms, motor control centers, and electrical equipment rooms in industrial environments, such as pulp and paper mills, petrochemical plants, refineries, steel mills, laboratories, and other process industries.
Read MoreFeatures and Benefits
- Supplies pressurization air, free of contaminant gases, to a controlled environment.
- Designed to maintain continuous positive pressure within the space.
- Configured with two separate banks of chemical filtration media. This allows a user to choose the media whose performance characteristics are particularly suited for targeted contaminant gases.
- Available in four horizontal and four vertical configurations, ranging from 500 CFM up to 4,000 CFM.
