The integrated ball castors make the unit completely flexible in terms of location.
The front panel opens for easy access to filter materials.
The D-LE 280 SD three-place extraction unit has an automatic switch-on device and regulates the air-flow rate automatically.
The display provides information about the number of channels, their extraction power and the condition of the filters.
A maintenance-free, brushless, two-stage, high-pressure fan ensures a dust-free working environment, and is also extremely quiet.
The extraction power is between 25 l/s and 37 l/s, depending on the number of loads in operation.
The extraction unit consists of a powerful, very quiet, brushless extraction fan, combined with a large-volume fleece bag with a dust collection capacity of approx. 10 kg and a downstream class “M” super-fine filter. This catches 99.98% of micro-dust particles with a grain size of 0.5 μ. This is significantly better than the 0.1% let-through value required by the trade association.
The extraction unit features automatic electronic switch-on, automatic cut-out with filter change indication for pre-filter and super-fine filter, and automatic air-flow regulation. The air-flow rate can be set according to the type of collection device (suction muzzle) and can be read on the display.
The air-flow rate and information about the degree of soiling of the filter materials can be read on the display.
