Condition: new, Year of construction: 2026, CORMAK SGDCW1000 Industrial Dust Extraction Unit with a Wet (Water) Filter The CORMAK SGDCW1000 industrial dust extraction unit with a wet (water) filter is an advanced device specially designed to work with deburring machines and grinding stations. It is perfectly suited for the safe extraction of dust with an increased risk of ignition and explosion – in particular aluminium dust, as well as during the processing of stainless and mild steel. By immersing contaminated air in water, it effectively neutralizes fire hazards during production processes. Main Advantages and Characteristics of the Device Fire safety: Wet separation of metal dust (aluminium, magnesium) significantly reduces the risk of explosions and ignition of sparks in the deburring machine's extraction system. High filtration efficiency: The extracted air passes through a water tank, where microscopic dust particles are permanently trapped in the tank. Heat recovery: After the cleaning process, the air reaches optimum humidity (approx. 60%) and can be safely returned to the production hall. Durable and robust construction: The device is made of high-quality corrosion-resistant materials and designed for continuous operation under demanding industrial conditions. Easy maintenance: Easy access to the filtration area and water tank facilitates daily cleaning and servicing. Technical Specifications Motor power — 7.5 kW Maximum capacity — 3000 m³/h (at 20°C and a medium density of 1.2 kg/m³) Fan rotational speed — 2900 rpm Maximum pressure — 4600 Pa Weight — 450 kg Filters — Mesh, 2 × 750 × 810 mm Suction inlets — 2 × Ø200 mm Iiedpfx Asz Ahurohysh Fan outlet flange — Ø180 / Ø225 mm Overall dimensions (W × D × H) — 1400 × 850 × 2170 mm Construction and Standard Equipment The construction of the wet separator has been optimized for perfect cooperation with modern deburring machines and finishing machines. The standard equipment includes: An efficient industrial fan with a high rotational speed, designed to generate high negative pressure. Two advanced mesh filters with dimensions of 750 × 810 mm. A spacious water tank with a drain for water replacement. Ergonomic inspection panels providing continuous visibility of the filtration process. A safe electrical system adapted to stringent industrial standards.
