Who uses the DC 450 CF - 230V and for what purpose
The Bernardo DC 450 CF - 230V dust collector is sized for professional workshops with 2-3 machines connected simultaneously. The 2800 m³/h flow rate and the 1 × Ø 130 mm / 2 × Ø 100 mm connection allow for flow distribution to multiple workstations via the supplied Y-adapter. For correct sizing, each machine typically requires 600-1,200 m³/h: the DC 450 CF - 230V model with 2800 m³/h flow handles 2-3 machines active concurrently. The FP 2 filter cartridge effectively captures fine dust (PM 10 and below), a critical feature for operator safety: wood dust is carcinogenic, and chronic exposure is regulated by European occupational risk regulations. In Krollit customers' workshops, the DC 450 CF - 230V is chosen by professional artisanal joinery workshops 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 machines connected.
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 joinery and production departments with multiple machines and fixed extraction systems.
The DC 450 CF / 230V is the single-phase version of the three-phase DC 450 CF / 400V. Same mechanical and filtration characteristics (2,800 m³/h, 4 m² surface, 300 L bag). For workshops without a 400V three-phase line, the 230V is mandatory; for workshops with three-phase, the 400V version offers better starting torque and longer motor life.
Krollit logistics and support
Bernardo shipping in 5-9 working days (7 days to the South). With a weight of 49 kg, it requires two people for unloading and handling, or a pallet truck. Dimensions 860 × 670 × 2210 mm: check the workshop height. Original Bernardo replacement filter cartridges, collection bags, and accessories are available from stock with 3-5 working days shipping. Customer support in Italian is available.

2800 m³/h flow rate and 1 × Ø 130 mm / 2 × Ø 100 mm connection suitable for 2-3 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 extended working 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 2800 m³/h flow rate 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 450 CF - 230V with 2800 m³/h flow handles 2-3 machines active concurrently.
For correct sizing, also consider system pressure losses: 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 450 CF - 230V is 1800 Pa: with piping longer than 10-15 m, the effective flow rate significantly reduces. For complex systems, consult a qualified installer.
Is the FP 2 filter cartridge really effective against fine dust?
Yes. The FP 2 cartridge is sized for filtering fine dust (PM 10 and smaller particles). Filtration 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 joinery workshops are subject to European regulations on exposure (Directive 2017/2398/EU). FP cartridge filters meet the efficiency requirements for standard professional use. For ultra-fine dust (exotic woods, composite MDF/chipboard), consider HEPA H13 cartridges (99.95% efficiency) as an optional accessory.
How long do filter cartridges last?
In standard daily artisanal use, an FP 2 cartridge typically lasts 2-3 years before requiring replacement. The sign is a progressive reduction in airflow 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 my workshop using domestic electrical lines?
For the DC 450 CF - 230V (230V, 1.5 kW S1 motor), check the available power. A 230V domestic line with a 3 kW meter: manageable for occasional use, at the limit for continuous use.
For intensive use, a dedicated meter is recommended. The motor's starting current can reach 1.5-2x the nominal power (S6 40%): 2.1 kW. On meters at their limit, starting can cause the safety breaker to trip, especially with other machines on. For professional workshops, a dedicated industrial meter for the dust extraction system is recommended.
How noisy is it?
Declared sound level 87 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 87 dB level is typical for dust collectors in this class. For prolonged use in enclosed spaces, the use of noise-cancelling headphones (mandatory PPE in professional joinery workshops 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.
