Mobile Filter for Gas, Fume and Dust Particle Extraction from flextraction

Fumex’s LF70 mobile filter for the extraction of airborne pollutants is available through flextraction Ltd, supplier and manufacturer of Local Exhaust Ventilation (LEV) products and sole UK representative for Fumex AB, Sweden. This filter unit is ideal for use in temporary workplaces or where a fixed installation would not be practical.

It is designed to extract gases, fumes and dust particles in educational, scientific and pharmaceutical laboratories, hospitals, electronic component manufacturing lines as well as in laser branding. The LF70 features highly efficient 3-stage dust filters comprising a G3 pre-filter, a F6 fine filter and an H12 HEPA filter which separate 99.97% of dust particles down to 0.3µm. For gases, fumes and other pollutants, a range of 4 different carbon filters are available depending on the gas to be extracted.

Using an easy to read digital display, shows which type of pollutant the filter is being used for and the easily adjusted airflow speed. For dust extraction, the filter starts at 0 hrs and the number of hours the filter has been operating is shown on the control panel. This will reset to 0hrs when the filter is changed. A LFD (differential pressure manometer) which indicates when the filter is full, is available as an option. For gas extraction the filter starts at the preset number of hours depending on the gas and the airflow. To obtain an exact air flow through the filter, a LFF (flow meter) is available as an option. A remote control to start and stop the fan is also an option. Depending on the application, the LF70 can be used with either one 75mm diameter extraction arm with an extracting airflow of 42 l/s or two 50mm diameter extraction arms extracting 2 x 21 l/s. Using a plexiglass hood to enclose laboratory or other sensitive instruments, the LF70 with a single 75mm diameter extraction arm is able to extract up to 70 l/s. The LF70 is EMC- LVD- and CE certified to meet EU Medical Directives and has a very low 56 dB(A) noise level at 100% rpm. It is compact, mobile and light in weight (25 kg) enabling it to be easily moved from one location to another and then placed under the work station.
