Who uses the DC 550 CF - 400V and for what purpose
The Bernardo DC 550 CF - 400V dust collector is sized for professional workshops with 2-3 machines connected simultaneously. The 4400 m³/h flow rate and 1 × Ø 150 mm / 3 × Ø 100 mm connection allow for flow distribution to multiple workstations via the included Y-adapter. For correct sizing, each machine typically requires 600-1,200 m³/h: the DC 550 CF - 400V model with a 4400 m³/h flow rate can handle 3-4 machines active simultaneously. The FP 2 filter cartridge 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 regulations. In Krollit customer workshops, the DC 550 CF - 400V is chosen by professional artisanal joineries with multiple machines, mixed workshops with standard dust collection needs, and growing workshops.
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 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. 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 joineries and production departments with multiple machines and fixed extraction systems. The DC 550 CF is the top model of the medium family: 2.2 kW motor (vs 1.5 kW for the 350/450), 4,400 m³/h flow rate, 8 m² surface, double 2×300 L bag. For workshops with 3-4 machines connected simultaneously, it is the correctly sized choice. Above it begins the industrial family (DC 650 and above).

Who is the DC 550 CF - 400V for
| Profile | Compatibility | Reason |
|---|---|---|
| Advanced hobbyist | Adequate | Oversized for standard hobbyist use. For more limited use, consider DC 180 or DC 250 CF. |
| Professional artisanal joinery | Recommended | 4400 m³/h flow rate and 1 × Ø 150 mm / 3 × Ø 100 mm connection suitable for 3-4 connected machines. Integrated trolley for movement between workstations. |
| Mixed metal-wood workshop | Recommended | FP 2 filter cartridge sized for fine dust: effectively captures both coarse chips and fine particulate matter. |
Not suitable for: industrial workshops with long fixed piping systems or large capacity machines (the industrial family DC 650/750/850 is correctly sized); applications requiring prolonged autonomy without emptying bags (the industrial family with multi-190 L bags offers greater total capacity); workshops with 5+ machines connected simultaneously; applications with flammable or explosive dust (certified ATEX extractors are required).

Frequently Asked Questions
Is the 4400 m³/h flow rate really sufficient for my machines?
It depends on the number and type of machines. For effective 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 planer/thicknesser 1,500-2,000 m³/h. The DC 550 CF - 400V with a 4400 m³/h flow rate can handle 3-4 machines active simultaneously.
For correct sizing, also consider the pressure losses of the system: each meter of Ø 100 mm flexible hose reduces by approximately 50-100 Pa, each 90° bend adds 100-150 Pa. The maximum vacuum pressure of the DC 550 CF - 400V is 1800 Pa: with piping longer than 10-15 m, the effective flow rate is significantly reduced. For complex systems, consult a qualified installer.
Is the FP 2 filter cartridge really effective against fine dust?
Yes. The FP 2 cartridge is designed for filtering fine dust (PM 10 and smaller particles). The filtering efficiency is typically 99% or higher for particulate matter above 1 μm.
Wood dust is classified as a definite human carcinogen for the nasal cavity (IARC Group 1). Professional joineries 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/chipboard composite materials), consider HEPA H13 cartridges (99.95% efficiency) as an optional accessory.
How long do the filter cartridges last?
In standard daily artisanal use, an FP 2 cartridge typically lasts 2-3 years before requiring replacement. The signal is the progressive reduction in air flow despite cleaning.
Filter cartridges are consumable material with a finite lifespan. Periodic 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 business day shipping.
Can I connect the dust collector in the workshop using domestic electrical lines?
For the DC 550 CF - 400V (400V, 2.2 kW S1 motor), check the available power. A 400V industrial three-phase line is required: the motor will not work on domestic meters.
For intensive use, a dedicated meter is recommended. The motor's starting current can reach 1.5-2x its nominal power (S6 40%): 3.0 kW. On meters at their limit, starting can trip the circuit breaker, especially with other machines on. For professional workshops, a dedicated industrial meter for the extraction system is recommended.
How noisy is it?
The declared sound level is 89.4 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 89.4 dB level is typical for dust collectors in its class. For prolonged use in enclosed spaces, the use of noise-canceling headphones (mandatory PPE in professional joineries according to safety regulations) is recommended. To reduce noise in shared workshops, consider sound-insulating cabins or positioning the dust collector in a dedicated compartment.
