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