Metal extraction systems

(5 products)

Bernardo metal dust collectors are specifically designed for belt sanders, grinders, and bench grinders: dynamically balanced steel impellers that resist abrasive metal particles, unlike common industrial vacuum cleaners with plastic impellers. The catalogue includes MSA series dust collectors from €469 (MSA 300, flow rate 300 m³/h) to €1,074 (MSA 1500, flow rate 1,500 m³/h), plus UGA 2 and Model D bases with integrated suction for direct installation under the machine. Official Bernardo distributor since 2007, with spare parts and technical assistance available.

Frequently Asked Questions

What is the difference between MSA 300, MSA 750, and MSA 1500?

The main difference is the airflow: MSA 300 (300 m³/h) for single entry-level machines with a Ø 100 mm connection, MSA 750 (750 m³/h) for professional belt sanders with integrated extraction up to 520 m³/h, MSA 1500 (1,500 m³/h) for workshops with multiple machines connected alternately or for 3.75 kW industrial Flott machines. As a rule of thumb, choose a model with an airflow at least 20–30% higher than the machine's required airflow.

Why use a metal-specific vacuum cleaner instead of a generic industrial vacuum cleaner?

Metal dusts (steel, stainless steel, aluminum) are abrasive and dense: they quickly destroy the plastic impellers of common industrial vacuums. The Bernardo MSA series features statically and dynamically balanced steel impellers, designed for continuous use with metallic material. Furthermore, the filtration must retain fine metal particles to comply with regulatory TLVs for M-class dusts (EN 60335-2-69).

Is the UGA 2 dust extractor base compatible with all Bernardo sanders?

No. The Bernardo MSA series extractors are sized for dry grinding, sanding, and deburring dust. For welding fumes, a local extraction system with an articulated arm and specific cartridge filters for fine metallic aerosols is needed, with filtration efficiency up to 0.3 µm. These systems are categorically different from dry dust extractors and require a separate assessment.

Are MSA extractors also suitable for welding dust and fumes?

Can I connect multiple sanders to the same dust extractor?

Yes, if the total flow rate required does not exceed the nominal flow rate of the extractor. With the MSA 1500 (1,500 m³/h) it is possible to connect two Bernardo MS 75×2000 belt sanders (520 m³/h each) as long as they are not both operating at full load simultaneously. To connect multiple machines in parallel, use gate valves on each branch: this isolates the unused suction point and maintains maximum vacuum on the active machine.

What is the routine maintenance for a metal dust collector?

The filter bag must be emptied before it reaches 80% capacity: a full bag reduces flow and overloads the motor. Cartridge filters should be inspected every 40–50 hours of use and replaced when the pressure drop exceeds the limit specified in the manual. Steel impellers do not require periodic replacement, but should be inspected annually for wear from coarse particles. Bernardo supplies compatible replacement bags and filters, which can be ordered through Krollit.

The Bernardo MSA series directly matches the machine based on the required flow rate: the MSA 300 (300 m³/h) covers entry-level belt sanders with a single Ø 100 mm connection, while the MSA 750 (750 m³/h, €879) handles machines with integrated 520 m³/h suction such as Bernardo MS series sanders and KBR belt grinders, with margin for peak loads. The MSA 1500 (1,500 m³/h, €1,074) is sized for workshops with multiple machines in alternating use or for the Flott BSM 150 A (3.75 kW) with its own 520 m³/h suction, which can operate in parallel.

For those who combine the dust extractor with a bench machine, the bases with integrated suction UGA 2 (€817) and Model D with MSA 500 (€1,046) eliminate flying hoses in the workshop: the collector is integrated into the pedestal, and the ducting goes down directly without pressure losses. Those with a stationary sander often choose this solution to keep the workshop tidy.

Steel, aluminum, and stainless steel dust falls into class M according to EN 60335-2-69, which requires a filtration system with an efficiency of ≥ 99.9% for particles over 0.3 µm. All Bernardo MSA models with balanced steel impellers are designed for continuous use in S1 service, suitable for the production hours of workshops and carpentry shops. For combinations with metal grinders or grinders, check the required flow rate of the machine in the technical data sheet before purchasing.
