Improve Indoor Air Quality and Odor Removal
VariSorb® SAAFCity high efficiency filters are designed to remove gaseous contaminants from urban environments, both indoor (outgassing from carpets, paint, solvent and detergents) and outdoor sourced (industry and transport). This includes VOC’s, SOx, NOx, Ozone. The VariSorb® SAAFCity filter is suitable for retrofitting into existing HVAC systems, for specification in new construction, or for direct replacement of 12″-deep, single header filters.
VariSorb® XL SAAFCity filters consist of filter elements assembled in a V-bank configuration in high impact polystyrene (HIPS) end caps, and Acrylonitrile Butadiene Styrene (ABS) profiles 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 seals gaskets are supplied upon request.
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. HIPS 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 incinerated. Always follow the local, state or federal regulations for disposal.
