Sample Gas Filters
The distance between the extraction point of sample gas and the analyser cabinet is normally bridged by tubes or hoses in continuous emission monitoring (CEM) systems. Depending on the method of analysis (FDIR, HFID, hot wet analysis, total hydrocarbons, etc.), these gas lines can be unheated or must be heated to prevent unwanted condensate formation.
Due to the nature of such installations, additional in-line filtration is required.
Bühler offers a wide selection of unheated and heated filters specifically designed for gas sampling applications.

Dry seals for compressors and turbines require clean, dry gas to maintain seal integrity and ensure longevity. Gas seal support systems as specified in API-614 require filters and sometimes water-removing coalescers to ensure gas quality to the seals.
For critical seal gas filtration, the ideal arrangement is to have “duplex” filters. In the duplex configuration, there is always one filter on-line filtering and/or “drying” the gas, even when the other filter element is being replaced.
Dry Seal Gas Duplex Filters meeting API-614:
• Reduce cost by eliminating expensive stainless steel fittings and assembly time. Compact design saves space
• Simple duplex housing arrangement reduces possibility for incorrect operation and potential for shutting off the dry gas seal flow
• Zero-leak integral transfer valve and double block valves provide assurance of tight shut off when replacing elements
• 316 stainless steel materials
• ASME code construction
• Available with coalescing (liquid removal) and filter (particulate removal) cartridges
• Designs to 2600 PSI

M&C Universal Filters reliably separate solids, in particular extremely fine particles,occuring in analysis techniques in gas filtration, using very fine, deep-acting filter elements.Thanks to their universal design, the filters can also be used as separators (without a filter element), liquid filters or, with adsorption cartridges, as an adsorption filter. For ambient or medium emperatures up to 180 °C, a stainless steel version FSS or FT-H version can be offered. Heated filters up to 320°C are also available.

willpore L
willpore L filters are made of reticulated foam impregnated with a liquid recipe based on active carbon powder. It has been developed to treat low concentration of odours, organic vapours, ozone even in air or in water.
willpore L is the combination of reticulated foam impregnated with a liquid recipe. Afterwards the obtained complex is dried in order to fix the different components of the recipe. Thanks to this process, we avoid particle loss. Furthermore, Willpore L technology gives the opportunity to add other properties to the final filter such as chemical catalyst or preservative.
Foam characteristics
Foams used are especially dedicated to filtration thanks to a reticulation process that gives to this medium a controlled porosity (from PPI 10 to PPI 25). Adjusting this parameter, pinta filtration is able to manage pressure drop as well as efficiency. For applications dedicated to water treatment, pinta filtration uses a dedicated foam resisting to hydrolysis, named TPPI (instead of SPPI for air treatment).
The following graph represents the impact of porosity between TPPI and SPPI on pressure drop (data given for a same carbon & weight, airflow of 90m3/h).

TURBOGLASS
Rigid pocket filter in microfiber of glass.
ll filter TURBOGLASS is constituted from a resistant plastic chassis to the heat, totally riciclabile. The leaking material is in microfiber of idrorepellente glass lacking in cellulose, in class of filtration from F5 to F9. The filter does not introduce to its inside some metallic member, as the assemblage of the chassis and the resistor of the leaking septum concurs to avoid ulterior reinforces. The glue chassis being completely on all sides, with sealing poliuretanico, resistant to acids, is lacking in any by pass of the air. The air crosses alone and exclusively the leaking septum. A gasket in polyurethane completes filter TURBOGLASS.
The leaking septum that it constitutes filter TURBOGLASS is 100% microfiber of glass. The microfiber of glass is folded with a system that allows to obtain a uniform spacing between the folds, for a better leaking efficiency and a better withholding of particles and consequently a greater one I accumulate of the powders. Such characteristic assures a resistor begins them much lowland and an elevated operating life of the filter.
The microfiber of glass having to its inside fibers in cellulose is not totally idrorepellente.

The filter type FBI is a filtering unit with a counter current cleaning system employed to separate pulverized solid products, which are suspended in the air or in other gaseous products. The filter is equipped with a tank to accumulate pressurized air and the sleeves' cleaning system, both contained inside the filter body. The cleaning system is controlled and managed by a cyclic electronic timer with a ?P incorporated. The filter is supplied with the work and pause sequences programmed and may be reprogrammed according to the client's requirement. It is also equipped with a three digit display to visualize the inlet differential pressure. The efficiency of the filter type FBI is within the values prescribed by the current anti-pollution italian law (d.P.R. 203/88). Its construction is also in conformity with european directive and italian law (d. Lgs. 277/91) On noise reduction in the working environment. The filter shape is cylindrical with the sleeves' extraction from the top. Its engineering is a result of the research and experience in the dry filtering with the use of sleeves and optimization of space in the plants. The air-product mixture is suctioned in the filter. The heavier product particles drop to the bottom by gravitational force whilst the lighter rise to the top and are filtered by the filtering sleeves wich are supported by steel frames. All filters may be executed in carbon steel, stainless steel Aisi 304 or Aisi 316, and aluminium.
