Condition: used, Year of construction: 2026, FM230-L1 low-noise vacuum extractor. Large design and powerful vacuum allows for removing sawdust and chips from machines and floors. Machine features Extractor with a powerful vacuum (horizontal system rotor) Metal, balanced rotor Strengthened motor Workplace vacuuming capability Large bags capacity Wide suction nozzle in the set Portable due to large wheels Ergonomic handle for machine manoeuvring Quiet work, high efficiency Due to its small size it doesn't take a lot of space in the workshop Many years of our team's effort resulted in creating a WhirlWind series multi-wing metal rotor, which, along with the rigid metal body, constitutes the heart of the extractor. Vacuum air-flow perfectly sucks out excess amount of sawdust produced during machining wood. Large design of the extractor is equipped with a solid frame providing stability and vibration-free operation. Entire construction is also strengthened with appropriately thick supports, which hold the cylinders along with the weight of the waste bags in proper position. Another advantage is the usage of an elastic and durable gasket, located in the integral part of the machine in order to improve the tightness of the entire system. By default, our extractors are equipped with burlap (filtering and waste) as well as additional, disposable, durable, plastic waste bags. Elastic metal bands ensure long-term reliable bags replacement. Usage of rotary wheels in bearings provides quick relocation of the machine.
