It offers an airflow rate of 7800 m³\/h, a filter surface area of 16.0 m², a maximum vacuum pressure of 2340 Pa, a suction diameter of 1 × Ø 180 mm \/ 4 × Ø 100 mm with adapter, a collection bag volume of 760 liters (4 × 190 L), a 3.7 kW (S1 100%) \/ 5.1 kW (S6 40%) 400V motor, a noise level of 80 dB, dimensions of 2700 × 582 × 1755 mm, and a weight of 125 kg. It features a multi-cartridge system with integrated cleaning brushes, an aerodynamically profiled steel fan, and a quick-release strap for bag replacement. Suitable for joinery workshops and wood processing laboratories.

Its maximum airflow of 7800 m³\/h and filter surface area of 16.0 m² distribute the flow across 6-8 machines active at the same time. The FP 2 cartridge filter with brushes effectively captures fine dust (PM 10 and smaller), a crucial feature for operator safety: wood dust is carcinogenic, and chronic exposure is regulated by European occupational risk legislation. Integrated cleaning brushes on the cartridges keep the filters efficient for extended cycles without manual intervention. In Krollit customers' workshops, the DC 750 CF - 400V is chosen by professional joinery workshops and industrial departments with fixed ducting systems, series production with multiple machines in continuous operation, and centralized dust extraction systems.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\n\u003cp\u003eThe Bernardo DC dust collector range is organized into 3 families:\n\nCompact family: DC 180 (850 m³\/h, hobbyist) and DC 250 CF (1,500 m³\/h, semi-professional). For workshops with a single machine at a time or occasional use.\n\nMedium family: DC 350 CF (2,800 m³\/h), DC 450 CF (2,800 m³\/h, single 300 L bag vs 200 L for the 350), DC 550 CF (4,400 m³\/h with double bag). For professional artisanal workshops with multiple connected machines.\n\nIndustrial family: DC 650 CF (5,310 m³\/h, 3 bags), DC 750 CF (7,800 m³\/h, 4 bags), DC 850 CF (9,500 m³\/h, top of the range). For joinery workshops and production departments with multiple machines and fixed extraction systems.\n\nThe industrial range (DC 650, DC 750, DC 850) shares the same philosophy: 3-4 FP 2 filter cartridges with integrated cleaning brushes, multi-bag system 190 L, quick-release strap, low noise level (80-82 dB). The DC 850 CF is the top of the range: 5.5 kW motor (vs 3.7 kW for the 650\/750), 9,500 m³\/h airflow (the highest), 20 m² surface area (vs 16 m² for the 750), 4 x 190 L bags. For industrial departments with fixed ducting systems and 8+ connected machines.

machines. For effective dust extraction, each woodworking machine typically requires 600-1,200 m³\/h: a miter saw 600-800 m³\/h, a panel saw 1,000-1,500 m³\/h, a jointer\/thicknesser 1,500-2,000 m³\/h.

The maximum vacuum pressure of the DC 750 CF - 400V is 2340 Pa: with ducting longer than 10-15 m, the effective airflow significantly reduces.

Professional joinery workshops are subject to European regulations on exposure (Directive 2017\/2398\/EU). FP cartridge filters meet efficiency requirements for standard professional use. For ultra-fine dusts (exotic woods, impregnated MDF\/chipboard composite materials), consider HEPA H13 cartridges (99.95% efficiency) as an optional accessory.\u003c\/p\u003e\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eHow long do the filter cartridges last?\u003c\/summary\u003e\n\u003cp\u003eIn standard artisanal daily use, an FP 2 cartridge typically lasts 2-3 years before requiring replacement. The sign is a progressive reduction in airflow despite cleaning.\u003c\/p\u003e\n\u003cp\u003eFilter cartridges are consumable material with a finite lifespan. Periodic cleaning (weekly or when a reduction in flow is noticed) significantly extends their lifespan: use compressed air from outside to inside, never with liquids or aggressively to avoid damaging the filter media.
