Extraction system for aluminium and PVC swarf from work units,. Silenced exhauster with double suction nozzle, that is also suitable for continuous operation, complete with automatic start with power supply from the mains or directly from the machine. The use of a high-capacity fan, makes it suitable for various extraction requirements. A wheel-mounted, quick-release, automatic vibrating fi lter and collection tank cleaning system, for the quick and easy disposal of exhausted material.
The extractors may be equipped, depending on the model, with cast aluminium side duct turbine suction units where high performance is required, or with centrifugal electric fans in the event greater intake capacity is needed. In both applications the impeller is fixed directly to the motor shaft, thus without transmission systems: this reduces component wear and tear and subsequent maintenance needs. These features, together with noiselessness, make the motor particularly suitable for continuous service.
Within the steel filtering chamber one can find, depending on the extractor model, a polyester filtering bag or a high performance cartridge filter, intended to protect the suction unit. These ensure a high retention of dust and guarantee purity of the outgoing air, thanks to a large surface area and at a high filtration efficiency. For the models fitted with a bag filter there is an automatic cleaning system, comprising a vibrating filter shaker operated by a pneumatic motor which as well as easing cleaning, provides greater durability and performance of the filter itself.
