Fumex’s LF70 mobile filter for the extraction of airborne pollutants is now available through Flextraction.

The filter is suitable 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 laser branding.

The LF70 is said to feature highly efficient three-stage dust filters, comprising a G3 pre-filter, an F6 fine filter and an H12 Hepa filter, which separate 99.97 per cent of dust particles down to 0.3um.

For gases, fumes and other pollutants, a range of four different carbon filters are available depending on the gas to be extracted.

A digital display shows which type of pollutant the filter is being used for and the adjusted airflow speed.

For dust extraction, the filter starts at 0hrs 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.

An LFD (differential pressure manometer) that 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, an LFF (flow meter) is available as an option.

A remote control to start and stop the fan can also be supplied.

Depending on the application, the LF70 can be used with either one 75mm diameter extraction arm with an extracting airflow of 42 litres/s or two 50mm diameter extraction arms extracting 2 x 21 litres/s.

Using a plexiglass hood to enclose laboratory or other sensitive instruments, the LF70 with a single 75mm diameter extraction arm can extract up to 70 litres/s.

The LF70 is EMC, LVD and CE certified to meet EU Medical Directives and has a 56dB(A) noise level at 100 per cent rpm.

It is compact, mobile and weighs 25kg, enabling it to be moved from one location to another and then placed under the work station.
