Who uses the DC 650 CF - 400V and for what
The Bernardo DC 650 CF - 400V dust collector is sized for woodworking shops and industrial departments with multiple machines running simultaneously, fixed ducting systems, or large-capacity machines. The maximum air flow of 5310 m³/h and the 12.0 m² filter surface area distribute the flow across 4-6 active machines simultaneously. The FP 2 filter cartridge with brushes effectively captures fine dust (PM 10 and smaller particles), 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 650 CF - 400V is chosen by professional woodworking shops and industrial departments with fixed ducting systems, serial production with multiple machines in continuous operation, and centralized dust collection systems.
Its place in the Bernardo range
The Bernardo DC dust collector range is organized into 3 families:
Compact 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.
Medium family: DC 350 CF (2,800 m³/h), DC 450 CF (2,800 m³/h, single bag 300 L vs 200 for the 350), DC 550 CF (4,400 m³/h with double bag). For professional artisan workshops with multiple connected machines.
Industrial 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 woodworking shops and production departments with multiple machines and fixed dust collection systems.
The 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 sound level (80-82 dB). The DC 850 CF is the top of the range: 5.5 kW motor (vs 3.7 for the 650/750), 9,500 m³/h air flow (the highest), 20 m² surface area (vs 16 for the 750), 4 x 190 L bags. For industrial departments with fixed ducting systems and 8+ connected machines. Investment justified for intensive continuous production.

Frequently Asked Questions
Is the 5310 m³/h air flow really sufficient for my machines?
It depends on the number and type of 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/planer 1,500-2,000 m³/h. The DC 650 CF - 400V with 5310 m³/h air flow can handle 4-6 active machines simultaneously.
For correct sizing, also consider the pressure losses in the system: each meter of Ø 100 mm flexible hose reduces pressure by approximately 50-100 Pa, each 90° bend adds 100-150 Pa. The maximum vacuum pressure of the DC 650 CF - 400V is 2340 Pa: with ducting longer than 10-15 m, the effective air flow significantly reduces. For complex systems, consult a qualified installer.
Is the FP 2 filter cartridge with brushes really effective against fine dust?
Yes. The FP brush cartridge is sized for filtering fine dust (PM 10 and smaller particles). Filtering efficiency is typically 99% or higher for particulate matter above 1 μm.
Wood dust is classified as a certain human carcinogen for the nasal cavity (IARC group 1). Professional woodworking shops are subject to European regulations on exposure (Directive 2017/2398/EU). FP cartridge filters comply with efficiency requirements for standard professional use. For ultra-fine dust (exotic woods, impregnated MDF/particle board composite materials), consider HEPA H13 cartridges (99.95% efficiency) as an optional accessory.
How long do the filter cartridges last?
In standard daily artisan use, an FP 2 cartridge typically lasts 2-3 years before requiring replacement. The signal is a progressive reduction in air flow despite cleaning.
Filter cartridges are consumable items with a finite lifespan. Regular cleaning (weekly or when a reduction in flow is noticed) significantly extends their life: use compressed air from the outside in, never with liquids or aggressively to avoid damaging the filter media. Original Bernardo FP 2 cartridges are available from stock with 3-5 working days shipping.
Can I connect the dust collector in a workshop with domestic electrical lines?
For the DC 650 CF - 400V (400V, 3.7 kW S1 motor), check available power. An industrial 400V three-phase line is required: the motor will not operate on domestic meters.
For intensive use, a dedicated meter is recommended. The motor's inrush current can reach 1.5-2x its nominal power (S6 40%): 5.1 kW. On meters at their limit, startup can cause the circuit breaker to trip, especially with other machines on. For professional workshops, a dedicated industrial meter for the dust collection system is recommended.
How noisy is it?
Declared sound level is 80 dB during operation. For reference: moderate road traffic 70 dB, normal conversation 60 dB, critical level for the ear after 8 hours of exposure 85 dB.
The 80 dB level is contained relative to the air flow. For prolonged use in enclosed spaces, the use of hearing protection (mandatory PPE in professional woodworking shops according to safety regulations) is recommended. To reduce noise in shared workshops, consider acoustic isolation booths or positioning the dust collector in a dedicated compartment.
