Stanje: novo, The AL-KO POWER VAC series units are used wherever strong suction power and high air flow volume are required simultaneously. Typical applications include chip extraction on saws in window manufacturing or direct extraction of milling chips on multi-head welding machines. Functionality: A vacuum of up to 10,000 Pa ensures that chips and dust are quickly and safely extracted directly at their source. This guarantees smooth production processes and consistent product quality. The bag filters guarantee a high separation efficiency for both coarse particles and fine dust. It is also possible to connect a duct system, allowing multiple processing machines to be linked to the dust extractor. All AL-KO POWER VAC units are equipped with the proven AL-KO OPTI JET filter cleaning system and come standard with a control unit featuring an integrated frequency inverter. This allows the extraction performance to be adjusted to specific operational requirements at any time. Applications: - Cleaning floors, machines, and workstations in industrial and trade environments - Extracting dust from hand-guided processing machines during grinding, milling, sawing, deburring Ledewwt E Ujpfx Aamohi - Vacuuming dry dusts up to dust class ST1 - Direct extraction at small process and work machines Advantages: - High suction power up to 10,000 Pa vacuum - Optimum filter cleaning thanks to jet pulse cleaning (AL-KO OPTI-JET®) - CLEAN dust barrier for improved cleanliness and health protection - Compact, modular design for minimal space requirement - Energy savings through standard frequency inverter for precise adjustment of extraction power - Low operating noise – integrated silencers and soundproofing elements enable installation directly in the working area

Stanje: novo, Oprema: odsesavanje prahu, For all industrial processes where dust and coarse particles are released, the clean air dust extractors of the AL-KO CLEAN UNIT D series are the right choice. Thanks to their powerful fans and highly efficient filter cartridges, these mobile extraction units ensure clean air in metalworking as well as in the plastics, food, and chemical industries. Functionality: Dust and coarse particles are extracted directly at the machine or via capture hoods and transported through a suction line to the AL-KO CLEAN UNIT D inlet. In a generously sized pre-separation chamber, coarse particles are separated out. The subsequent filter cartridges, classified as dust class “M,” remove the remaining fine dust. The differential pressure-controlled filter cleaning system cleans the filter cartridges of adhering particles even during operation. Venturi nozzles on the filter cartridges increase the cleaning effectiveness, ensuring consistent suction power and long filter life. Collected dust is deposited in an easily movable container with a disposable collection bag for low-dust disposal. The purified air is released back into the room from the top of the unit. Applications: Lhedpewwkrfjfx Aamji - Direct extraction of dust and chips - For single or multiple extraction points - Suitable for connection to machines, extraction tables, booths, and ductwork - For metal and plastic processing, and many other industries - In grinding, polishing, filling processes, and much more Advantages: - High suction power thanks to an efficient fan and cleanable filters with long service life - Suitable for a wide range of applications - Extremely quiet due to highly effective sound insulation - IE3 motors for high energy efficiency - Plug-and-play
