DC3900L twin dust extractor


The DC3900L twin is a mobile but very powerful dust extractor optimized for large quantities of dust due to its integrated pre-separator. It is particularly well suited for concrete grinding since 80-90% of the coarse material is removed in the pre-separator. With such a large amount of material being separated in the pre-separator only smaller particulate makes it to the filter medium thus extending your filters life. The DC3900L is fitted with the continuous bagging system known as the Longopack. Filtration is done in three stages consisting of a cyclone, pre-filter and a certified hepa filter. HEPA filters used in our mobile extractors are individually tested for effectiveness. Improvements to the DC3900 twin over its predecessor the DC3800 twin include, lowering cyclone and more serviceable motor package. The DC3900L twin provides a powerful machine capable of handling heavy applications in a compact easy to move and transport package. Using single phase 120v power (20A plug) the DC 3900L twin provides a high capacity machine with a convenient power supply. The air flow capacity is suitable for concrete floor grinding machines with diamond discs of up to 500 mm/20" diameter. Other hand held tools with discs up to 9" can also be used with this machine.
