About Odor Absorption (Carbon) Systems

The 2000 Series OA or Odor Absorption units incorporate all carbon or other absorptive medias ( alumina, potassium permanganate, zeolite and specially treated carbons) in-lieu of a HEPA filter. The “L” version will accommodate up to 60 lbs of carbon with one pre-filter and the “S” version will accommodate up to 75 lbs of carbon with one pre-filter.

The 2000 Series (2000 CFM) unit is the most powerful odor absorption system and is used only in conjunction with 5 ton HVAC units or larger. The 2000 is a popular system for larger homes and occupied spaces. While it can be attached to a 5 ton or larger HVAC unit, this system is often used as a stand alone system in the “S” configuration to move carbon filtered air throughout a home or larger area.

Absorption of a Wide Variety of Gases and Odors

For many applications the reduction and or removal of a specific gas or odor is the primary issue. The ability to combine the all carbon units with the variable speed ECM motors allows for finite air flow control (CFM) of the specific gas through the carbon to obtain best adsorption rate and maximize single pass removal efficiency.

In the past three decades Pure Air Systems have been used to remove gases from Acetone to Toluene and everything in between. They have also removed organic and inorganic solvents and all types of odors from a wide variety of sources.

Variable Speed Motor

The 2000 Odor Absorption system represents one of the more powerful carbon air filtration systems in our product line and is used in a wide variety of filtration applications around the world. The 2000 unit utilizes a 1 HP GE (Genteq) ECM variable speed motor rated at 120/240 volt, 50/60 Hz and provides over 2000 CFM of carbon filtered air with finite control of volume and speed while using up to 50% less electricity than standard induction motors. The 2000 units offer true 21st Century digital motor technology that is unavailable in any other system of its size.

Horizontal and Vertical Configurations

Partial By-Pass, In-Line or Stand Alone Configuration – “L” and “S” Versions

The 2000 unit was designed to be used in a wide range of applications and installation configurations. Either the “L” or “S” versions can be attached to any forced air ducted heating/cooling system in the partial by-pass configuration; in-line in HVAC applications for same air volume applications or stand-alone configurations. While the “L” version is most often used in partial by-pass configurations, the “S” unit can be used as well for situations where the “L” unit will not work. Either the “L” or “S” versions can be used for stand-alone applications.

Unlimited Installation Variations

Split housing design for “L” unit and multiple operations for “S” unit allows for unlimited installation variations. The 2000 “L” unit comes in two separate sections, the top half houses the three filters and the bottom half houses the blower/motor assembly and controller. The top and bottom are symmetrical so they can be rotated in any of four directions for best inlet or discharge configuration. This also allows for best access to the filter section via the filter access door. The “S” unit is a single piece unit that can be mounted horizontally right side up or upside down or in a vertical position.

Controllers for the 2000 Odor Absorption Series Units

HVAC Controller

The HVAC controller is most often used when the 2000 unit (either “L” or “S”) is attached to a heating/cooling system in the partial by-pass configuration. The HVAC controller allows the 2000 system fan unit to modulate (speed up and ramp down) in conjunction with the HVAC fan/motor operation.

VCU Controller

For applications where the 2000 unit is used either in-line with an HVAC system or as a stand-alone unit, the VCU controller is utilized. The VCU controller allows for air flow speed control from 1% of volume to 100% of volume in 1% increments.
