Filter Max DF - Modular dust multi purpose collector

FilterMax DF is a efficient and compact solution to your dust and fume problems. FilterMax DF handles the air polution from metal industries as well as non explosive dust from other industries. The filter has the capacity to handle up to 13 000 m?3;/h (7800 cfm). A wide range of cartridges for different purposes are available. With it’s sturdy design, smooth inner surfaces, optimized angles of repose and digital control system, the filter fulfils stringent demands for continuous operation and effective filtration. The modular design makes it easy to to expand the capacity of an installed system and will also make transportation, handling and installation as easy as possible.

To simplify use and guarantee optimum performance, FilterMax DF is equipped with Nederman’s automatic cleaning system. The pulse-jet system shoots short, powerful jets of air into the filter cartridges. The dirt is released from the filter surface and falls down into a container. The pulse-jet system cleans the filter cartridges in sequence while the filter is in operation. The FilterMax DF can also be cleaned after operation if so desired. The FilterMax DF cartridge is a high performance, compact filter cartridge. The design is optimized for efficient media use and good cleaning properties. The small inner volume in combination with the air distributing support cage gives efficient cleaning. Shallow open pleats allows efficient removal of dust. The cartridges is available in different materials. The flat pocket shaped minimizes the area of the “lost” media on top of the cartridge.

FilterMax DF W3 kit The kit includes dP Control kit, filter regulator, shut off valve, flashlight and plastic bags for the dust contai- ner. With this kit the FilterMax DF is BGIA-certified for the highest available welding fume category (W3). Welding fume category W3 means that the unit is able to reliably extract and clean low, medium and high alloyed steels, e.g. containing a part of nickel and chrome of 30% and more with a separation efficiency of ? 99%. With this kit the FilterMax DF is certified according to the international effective standard DIN EN ISO 15012-1 (2005) that controls industrial and health protection for welding and related processes	12375080	12375080
