Respirable Crystalline Silica (RCS). is to be avoided at all costs.  One of the reasons why the Sigma air banker is so successful. The air banker dust extraction system manufactured by Sigma Group addresses the needs of equipment required in a stone masons workshop.  The banker is a wet extraction method, involving a three stage filtering process. The dust is drawn into the banker through a fine mist of water.  This ensures that most of the dust particulates are "dropped" into the water reservoir. The air is then sent through a set of wet filters, where further cleaning takes place. Finally, the air passes through a set of dry filters before going to atmosphere.

There are a number of advantages to the Sigma air banker design. Maintenance of any type of air banker is essential in order to ensure it remains effective. The wet filters in the Sigma air banker are of a cassette design, allowing easy removal for cleaning.  The filters are easily cleaned, simple washing with clean running water brings the filters back to efficient working condition. The water jets are designed to be removed and cleaned, no tools are required for this process.

The alternative dry cartridge  filtering  systems pose a hazard during maintenance, as the filters and dry dust contained in the bench have to be handled during maintenance.  The dry filter cartridges have a limited life, increasing the running costs!  Exposure to dust is to be avoided whenever possible, that is why Sigma Group have developed the wet extraction air banker.

Crystalline silica is present in most types of stone, concrete and brick products.  Consequently a hazardous  working environment is created whenever these products are to be worked or re-worked, either with power tools or indeed masons hand tools.  The dust created during these processes is categorized as Respirable Crystalline Silica (RCS)

LEV TESTING: IF YOU REQUIRE A TEST & INSPECTION PLEASE CONTACT US HERE⇒       Our LEV testing engineers are qualified to British Occupational Hygiene Society (BOHS) P601 – Initial Appraisal and Thorough Examination & Testing of LEV Local Exhaust Ventilation Systems. As stated in HSG258 competence is a legal requirement  

INFORMATION:  An employer who uses local exhaust ventilation (LEV) to control any dust, fume or vapour etc. It is a legal requirement to ensure that it is operating effectively and is in good repair. It is your legal obligation to ensure a formal examination and test of the LEV system is carried out. LEV testing must be carried out at least once every 14 months.
