Būklė: geras (naudotas), Gamybos metai: 2018, The AMBITOWER 10 series filter ventilation unit (filtration tower) is designed for extracting welding fumes in production halls. These efficient, compact hall ventilation systems are used wherever selective smoke detection alone is insufficient or direct capture during welding operations on large or complex metal components is unfeasible. Filtration towers not only provide effective pollutant separation but also contribute to significant savings in hall heating costs during winter. Depending on the application, energy costs can be reduced by up to 70%. This is ensured, among other things, by high-performance, stationary M-class filter cartridges that guarantee 99% separation efficiency, allowing warm, purified air to be recirculated into the hall without the need for fresh outside air supply. Areas of application for Keller Ambitower 10 stationary welding fume filtration systems: - Extraction of welding fumes in production halls (hall ventilation systems) - Ideal for all work areas where local extraction is impractical or impossible - Metal industry - Mechanical engineering Iijdsi Atb Tspfx Aauoa - Automotive industry - Vehicle construction - Aircraft manufacturing, etc. Technical parameters: - Motor power: 7.5 kW - Integrated frequency inverter - Airflow capacity: 10,000 m³/h - Filtration surface area: 90 m² - Antistatic filter cartridges - Noise level: ≤ 75 dB - Year of manufacture: 2018 - Complete technical documentation included Dimensions: - Width: 2.35 m x 1.35 m - Height: 3.50 m - Weight: 1,800 kg

Būklė: naujas, Vacomats are mobile dust extractors capable of removing large volumes of dust and chips in the smallest of spaces. These clean air extraction units (negative pressure systems) are designed for indoor installation and can be used for single- or multi-machine extraction with air volumes of up to 10,000 m³/h. Manufactured in accordance with the latest EU standard EN 16770, they are especially suitable for woodworking operations where special safety requirements exist due to the risk of dust explosions. Suitable for handling substances in dust explosion class St1. Filter cleaning for the Vacomat XPe series is carried out electro-mechanically via an efficient shaker motor, which starts automatically—once all connected machines are switched off. Control is performed via potential-free contacts querying the woodworking machines. The motorized shaker system is included in the scope of supply.
