Condition: excellent (used), Year of construction: 2023, machine/vehicle number: 2804221, functionality: fully functional, input frequency: 50 Hz, type of input current: three-phase, volume flow: 18,000 m³/h, suction capacity: 18,000 m³/h, filter area: 60.6 m², actuation type: electric, The EK-24 unit is a dust and chip extraction and filtration system for wood and wood-based material processing. The unit is manufactured by the Polish company Euro-Komplex, which specializes in the design, production, and installation of comprehensive dust extraction systems used in various industries, particularly in woodworking and furniture factories. The filter effectively removes contaminants from multiple machines simultaneously, such as circular saws, panel saws, four-sided planers, veneer coating machines, CNC machines, milling plotters, and sanders. Technical specifications: • Airflow: 18,000 m³/h • Filtration area: 60.6 m² • Number of filters: 48 pcs / 2000mm / 200mm • Electrovibrator: 0.09 kW x 2 • Control cabinet with frequency converter • WTK fan • Air lock • Dry fire tube The filter's robust and solid construction is made of hot-dip galvanized or powder-coated steel with a thickness of 2mm, and the inlet tunnel and reinforcements are made of 3mm steel. The structural elements are fastened with 8.8 screws with Teflon inserts. It is worth noting that the filter basket used is uniform and smooth, without welded elements, which facilitates airflow with waste fractions without depositing them on the basket walls. The EK-24 is equipped with an 0.09 kW electrovibrator in an ATEX system, used to clean the filter bags made of antistatic and waterproof material with a weight of 350g/m² and an air permeability of 240l/dm²/min. The cleaning system is fully automated and operates in appropriately selected time cycles adapted to the type of dust being extracted. Thanks to the use of an air return lock (summer/winter flap), in winter, the cleaned and filtered air returns to the production hall, which has a very beneficial effect on maintaining the appropriate temperature and provides measurable financial benefits. The WTK fans used in the EK-24 have self-cleaning impellers and a reinforced design, which guarantees stable operation for a long time. Electrical control is carried out using a control unit equipped with protection and a time control system for the electrovibrator and the fan motor. The control cabinet is equipped with a frequency converter, which enables the adjustment of the fan motor speed and provides very precise control. The air lock is used to separate the filter zone from the external zone. It blocks the airflow, allowing only wood chips to pass through, so they fall freely into the bag without an air blast. The air lock is equipped with a system that mitigates the impact of the impeller in case a large solid object enters the unit. Pedpfx Alezba E Iswjgt It is equipped with a dry fire tube mounted on the filter, used to quickly supply water or extinguishing agent to the closed filter chamber using internal sprinklers. The installation is equipped with a fire brigade connection necessary to connect fire department equipment or a hose directly from a fire hydrant. The filter also has a pressure relief device, which lowers the pressure in the event of an explosion. It is designed to relieve an explosion developing inside a protected device, such as hoppers, silos, separators, filters, sorters, etc., where an explosion hazard exists. By releasing the explosion into the environment, the explosion pressure is reduced to a value below the allowable pressure resistance of the protected device.

Condition: like new (used), Year of construction: 2019, Vacomat 350 XP TWIN Pgodpfx Aozp Edwelwot The Vacomat 350 XP TWIN is a high-performance dust extraction unit and a true energy-saving marvel among mobile dust extractors. Two frequency-controlled motors (5.5 kW each) ensure that the suction power is adjusted accordingly, especially under highly variable operating conditions. This ensures that only the energy that is actually needed is consumed. This dust extractor handles air volumes of up to 10,000 m³/h and is ideally suited for extracting dust from large CNC machines or entire machining centers. The innovative and highly intelligent control system automates the extraction process in conjunction with the connected machines. Extraction starts automatically as soon as a connected machining center is switched on. If the power requirement is lower, only one fan is started. As soon as several extraction points are in operation, the second fan is automatically switched on. As standard, the filter sleeves are cleaned automatically during operating breaks, as soon as all connected machining centers are switched off. Our patented filter shaking system then ensures gentle cleaning via a pneumatic/mechanical process using a compressed air connection (inlet pressure 6 bar, air consumption per cleaning cycle approx. 11 l). Optionally, and particularly recommended for very high and extremely fine dust concentrations, such as gypsum dust, an efficient pressure pulse cleaning system is available. The cleaning process via the compressed air tank takes place offline, after the extraction operation (NOTE: height then +100 mm and length +350 mm). Our Vacomats are manufactured using a modular system. As standard, the dust and chip mixture is discharged into four dust-tight chip collection containers (4 x 120 l) with durable plastic liners. A negative pressure channel securely holds the foil bags in the collection container. Viewing windows make it easy to check the fill level. Low energy consumption thanks to a modern, high-efficiency motor (IE3) "Made in Germany" and a flow-optimized internal housing with low air resistance. Heat recovery through a recirculation system: The warm exhaust air is filtered and fed back into the workshop. Low noise level: A double-walled filter sleeve housing absorbs the extraction noise directly inside the Vacomat. In addition, the fan housing is soundproof. Approved for indoor installation in the wood dust area - manufactured according to the new DIN EN 16770 standard. Healthy return air: High-quality, specially developed filter materials made of antistatic polyester needle felt filter out 99.9% of dust and chip waste from the air (dust class M for St 1 dust, according to TRGS 553). Increased safety through fire and explosion protection measures according to DIN EN 16770: pressure pulse tested up to 20,000 Pa, automatically activated powder extinguishing system - no water damage! Operational reliability: A pressure gauge continuously monitors the extraction performance. Error messages are displayed by the signal light. Low follow-up costs due to high-quality components and long service life of the filter medium: For example, an extra-large settling chamber ensures an initial separation of coarse chip waste. This prevents the filter sleeves from being additionally loaded with material. Low maintenance effort thanks to the maintenance unit on the motor console and easy access to the inside of the filter. All specifications according to the manufacturer.
