The MG range of wheeled and noise-dampened exhausters includes models sized for all workplace cleaning needs and for the proper evacuation of aluminum and PVC chips. The characteristics of each model are identified by its code. The number indicates the size of the swarf exhauster; the letters have the following meanings: • V: suction system with fan for high flow rate requirements; • VP: suction system with fan and automatic start directly from the machine; • T: turbine suction system for high head requirements; • TP: suction system with turbine and automatic start directly from the machine. Models with automatic start have autonomous power supply from the network; a special connection system to the machine’s PLC allows them to be operated based on the work cycle. Other models can be powered directly from the machine’s electrical panel, if equipped, and are operated by the PLC through the provision of electrical power. Alternatively, they can be connected to the electrical outlet and started manually. All models are noise-dampened and suitable for continuous operation. They are equipped with an antistatic filter suitable for the suction of aluminum, steel and PVC chips, an pneumatic filter cleaning system, and a quick-release collection tank mounted on wheels for easy and quick disposal of the exhausted material.
Manual work-area cleaning
The suction system has a die-cast tangential suction inlet, available in diameters of 100 mm or 160 mm (depending on the model). The tangential inlet allows optimal separation of debris from the air, reducing maintenance, energy consumption and improving overall efficiency. The system is connected via a plastic pipe with metal reinforcing, with the suction presettings mounted on the cutting machines, cutting-off centres and machining centres.
The extracted material is then deposited in a suitable container with quick release, made of steel and mounted on 4 wheels, which allows disposing of the swarf resulting from machining in a simple and fast manner.
The support frame is equipped with 2 fixed wheels and 2 pivoting wheels with brake, which ensure a high degree of mobility and handling ease. Locking the wheels with brakes allows their position to be fixed stably near different work areas.
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.
