Condition: like new (used), Year of construction: 2019, Vacomat 350 XP TWIN 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. Bwodszp Edwepfx Aiger 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.

Condition: new, In addition to pigments and additives, wet paints also contain other harmful substances that must be extracted without fail. AL‑KO COLOUR JET extraction units are the ideal solution here, offering four performance levels to ensure sufficient capacity at all times. Bwodpfx Aiswv T R Uogor The devices in the COLOUR JET series are optimally designed for the extraction of paint mist and solvents at wet painting workstations. The front guide plate ensures collection of emissions from below and at the side inlets, as solvents from paints settle and accumulate near the floor. At the same time, the guide plate ensures uniform air distribution across the filter and protects the filter medium from direct impact. Paint pigments are separated out via the large-area exchangeable filter, and the cleaned exhaust air is then routed outdoors via a pipe or hose. Applications: - Wet painting workstations in trade, industry, and workshops - Painting stations with ATEX Zone 2 Advantages: - Clean and safe painting workstations thanks to high extraction performance and an effective filtration system - Flexible use due to mobile design - Cost-effective and powerful, in many cases a substitute for a closed spray booth - Safety via certification for use in potentially explosive atmospheres (ATEX Zone 2) - Individually adaptable with a wide range of accessories

Condition: new, Year of construction: 2025, Mobile Paint Container Take your painting process to the next level with mobile convenience. Mobile paint booths in a container design for painting and coating various objects. They are specifically designed for mobility, making them easy to transport and set up on different construction sites. The booth is typically equipped with a ventilation system to ensure air quality, lighting, and a filtration system to prevent paint overspray. The ventilation system ensures that fumes and particles released during painting are contained within the booth, preventing any danger to the surrounding area. Mobile paint booths are a practical and flexible solution for companies that need a portable and effective painting system that can be transported from one construction site to another. Design and Features Overview Our mobile 20-foot Sapi paint containers consist of a robust steel frame with welded wall and ceiling panels. We can add special equipment such as cranes or lifting devices inside. The floor is made of teardrop plate. Both door panels contain ventilation grilles fitted with fine-pored filter mats. One panel is designed as an emergency exit for safety reasons and features a viewing window. It's also worth mentioning that these aren't simply converted shipping containers! We manufacture all of our containers from scratch. We use only the most robust materials that meet our requirements and have also been safety-tested and proven. Conventional shipping containers would not meet the required safety standards. Paint extraction system in the mobile painting container Bwodpfjwf Dmxsx Aiger The paint mist extraction panel for paint mist separation is located in front of the rear wall and is equipped with multi-layer filter mats. The extraction panel consists of a galvanized housing, folded with guide plates, including various suspension and fastening elements for the filter assembly. The powerful, explosion-proof extraction fan with drive motor is installed on a console in the rear wall area on the outside of the container. Next-generation mobile paint booths: Meeting EU requirements and advancing coating solutions The new generation of mobile paint booths must meet the highest EU requirements. The inclusion of new coating systems such as hydro-based paints, polyurethane resins, epoxy zinc dust, or epoxy iron mica paints places high demands on existing paint booths. Therefore, we have developed a new and unique mobile paint booth for the next generation of coating solutions. A key criterion is the transport of workpieces for painting and further processing steps. Whether it is dry paint mist separation or wet washing, air humidification or air drying, condensation drying using low-temperature processes or warm air drying, or whether workpiece pretreatment is carried out using high-pressure washing with water in a recirculating system, compressed air blasting, or wheel blasting technology.
