Improve Indoor Air Quality and Odor Removal
VariSorb XL SAAF City specialises in removing gaseous contaminants from urban environments, offering superior performance in reducing VOCs, SOx, NOx, and Ozone levels from both indoors and outdoors.
Construction
VariSorb XL SAAFCity filters consist of filter elements assembled in a V-bank configuration for assembly in front or rear access standardized universal holding frames or side- access track systems to fit standard dimension filter sections in air handling units. VariSorb XL SAAFCity comes factory-ready for installation. No special tools are needed to install or replace the filter element. The individual VariSorb seals and holds in the frame with the latching system or in the track with its header and the track- specific gasket system. Side seal gaskets are supplied upon request.
Media
VariSorb XL SAAFCity filters are designed for combined particulate and gas-phase removal of medium and low concentrations of gas-phase contamination in urban fresh air and recirculation AHU systems. The cell sides are fitted with pleated packs, comprising mini carbon granulate media embedded between two non-woven synthetic support layers. The air inlet side is provided with a layer of class M5 prefilter media. The pleat packs are arranged in a V-shape to utilize maximum amounts of media for the given face area. Each VariSorb XL SAAFCity is plastic bagged and carton packed.
Spontaneity and Yield
Unlike traditional granular bed chemical filters, the granular micro-structure ensures a much higher effective active area per kg of media, resulting in a high spontaneity of reaction. Combined with the dense packing of the micro-structure, this creates a tortuous path for the contaminant, resulting in a high yield for the filter. The construction greatly reduces pressure drop, eliminates by-pass and abrasion. The entire VariSorb XL SAAFCity can easily be disposed-off and is fully incinerate. Always follow the local, state or federal regulations for disposal.
Application Guide
VariSorb XL SAAFCity uniquely combines particulate prefiltration and gaseous filtration in one filter element. Use of prefiltration is essential to avoid dust settling on the chemical media. This ensures optimized lifetime of the chemical filter system without an increase in pressure drop.
