Optimum noise insulation for especially smooth running.
Easily replaceable, two-ply disposable filter bag in a practical mesh basket.
The integrated castors make the D-LE 255 extraction units highly mobile.
The large-area super-fine filter located downstream of the filter bag catches 99.98% of even micro-dust particles with a grain size 0.5 μ.
CAD CAM connection
Automatic switch on and off
Brushless Suction engine
High extraction power from industrial high-pressure fan motors, highly effective filtration and optimum noise insulation make sure these units stand out from the crowd. Our range of models provides the best possible device for every type of use. The D-LE 255 SD is designed for one to two extraction points. Best suited for use in preparation stations, it is fitted with an automatic switch-on device and the latest electronic air-flow rate regulation.
Flow rate control device
The air-flow rate is regulated automatically. The air-flow rate at the suction funnel remains constant, irrespective of the degree of soiling of the filter material. In a fraction of a second, the electronic control system detects a turning hand piece and initiates extraction immediately. At set time intervals, the extraction unit performs a self-test, during which the air ducts are sucked clear.
The air-flow rate can be set to suit the type of collection device (suction muzzle) and its air-flow rate, and can be read on the display.
The extraction unit consists of a powerful, very quiet extractor fan combined with a large paper filter bag, which can collect approx. 10 kg of dust and features a super-fine filter downstream. This catches 99.98% of even 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.
