Condition: new, functionality: fully functional, Year of construction: 2026, CORMAK DC2200 Model The CORMAK DC2200 is a powerful and robust cyclone dust extractor, designed to efficiently purify the air in woodworking shops, furniture factories, and metalworking facilities. Thanks to its cyclone separator, high-performance radial fan, and modern filtration system, the machine ensures effective particle separation and long-term high efficiency. Main Advantages of the CORMAK DC2200 High extraction capacity – up to 2800 m³/h – effective removal of dust and shavings from multiple workstations simultaneously Cyclone separator – separates larger particles before the filter, extending its service life Powerful 2.2 kW (2200 W / 50 Hz) motor – stable and reliable continuous operation Large 151-liter metal container – convenient and safe waste collection Filtration area of 4.8 m² – ensures high efficiency in capturing fine dust particles Compact, mobile design – sturdy frame with transport wheels for easy movement Quiet operation – optimized fan design reduces noise without sacrificing performance Design and Technology The CORMAK DC2200 is equipped with a 365 mm radial fan, generating a maximum static pressure of 2220 Pa. This allows efficient air suction through long ducting systems and multiple workstations. The extractor offers three suction inlets (3 × Ø100 mm) and one main inlet (Ø200 mm) for flexible setup according to the production area layout. The cyclone separation system effectively removes heavier particles at the inlet, directing only pre-cleaned air to the container. The cylindrical filter (Ø370 × 612 mm) ensures consistent airflow even during intensive operation. Performance and Ergonomics The DC2200 extractor is designed for daily use in small and medium-sized workshops. The 151-liter container (Ø620 × 570 mm) provides long working cycles without frequent emptying. With its compact dimensions (1320 × 900 × 1840 mm) and lightweight design (136 kg net), the unit fits easily into any workspace.
