Introduced in 1999, the 1200HS 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 1200HS unit utilizes a ¾ HP GE (Genteq) ECM variable speed motor rated at 120/240 volt, 50/60 Hz and provides over 1200 CFM of HEPA filtered air with finite control of volume and speed while using up to 50% less electricity than standard induction motors. The 1200HS units offer true 21st Century digital motor technology that is unavailable in any other system of its size.

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

The 1200HS 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.

Controllers for the 1200HS Plus Series Units – HVAC and VCU Controllers

The HVAC controller is most often used when the 1200HS unit (either “L” or “S”) is attached to a heating/cooling system in the partial by-pass configuration. The HVAC controller allows the 1200HS system fan unit to modulate (speed up and ramp down) in conjunction with the HVAC fan/motor operation. For applications where the 1200HS 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.

Split Housing Design for “L” Unit and Multiple Operations for “S” Unit Allows for Unlimited Installation Variations

The 1200HS “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 filer 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.

Three-Stage Filtration

The 1200HS 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 Gas and Odor Absorption

For applications where the issue is primarily odors and/or specific gas reduction or removal the 1200HS 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.
