The 2000 Series (2000 CFM) unit is the most powerful HEPA system and is used only in conjunction with 5 ton HVAC units or larger. The 2000HS is a popular HEPA 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 HEPA filtered air throughout a home or larger area.

Variable Speed Motor

The 2000HS HEPA Shield system represents one of the more powerful certified HEPA air filtration systems in our product line and is used in a wide variety of filtration applications around the world. The 2000HS 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 HEPA filtered air with finite control of volume and speed while using up to 50% less electricity than standard induction motors. The 2000HS 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 2000HS 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 2000HS “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 2000HS Plus Series Units

HVAC Controller

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

VCU Controller

For applications where the 2000HS 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.

BCU (Bluetooth) Controller

The BCU speed controller allows you to adjust the speed from 0 – 100% in 1% increments. The app shows the speed in percent of air volume capacity.

Three-Stage Filtration

The 2000HS series, like all our systems, use a three-stage filtration process. Each unit includes a commercial grade dual-layer polyester high capacity ring panel that is the first stage of filtration and is designed to remove the larger particles and protect the carbon and HEPA filter. The second stage is the 15lb carbon media that is designed to remove odors and gases. The final stage is the certified, commercial grade, metal framed HEPA filter rated initially at 99.99% at 0.3 microns.

All Carbon Option for Odor Absorption Available

For applications where the issue is primarily odors and/or specific gas reduction or removal the 2000HS can be configured with all carbon media in-lieu of the HEPA. 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.
