Who uses the Model D with MSA 500 extraction system and for what purpose
The Bernardo Model D base with MSA 500 system is an integrated solution for workshops that work with belt sanders and bench grinders. It combines three functions in a single structure: machine support (400×285 mm support surface), metallic dust extraction (1,275 m³/h), chip collection, and workpiece cooling via an integrated water tank. The statically and dynamically balanced steel fan ensures smooth operation and reduced noise. The double internal Ø 35 mm nozzles and double external Ø 50 mm nozzles allow simultaneous connection of two extraction points, a solution suitable for double-wheel grinders that produce dust from both sides. The integrated water tank for workpiece cooling improves surface quality and reduces the risk of thermal deformation during prolonged sanding. In Krollit customers' workshops, it is chosen by mechanical workshops, artisanal grinding shops, blacksmiths, and sharpening workshops looking for a complete and self-aspirating workstation.
Its place in the Bernardo range
The Model D base with MSA 500 is an integrated solution, distinct from the standalone extractors in the Bernardo range. Above it, as independent extractors, the range offers MSA 300 (870 m³/h, 230V single-phase, single Ø 100 mm connection), MSA 750 (1,100 m³/h, 400V, double Ø 100 mm connection), MSA 1500 (1,500 m³/h, 400V, double Ø 100 mm connection). The practical difference: standalone MSAs connect via flexible hoses to separate machines, while the Model D base directly integrates machine support and extraction. The Model D has a flow rate of 1,275 m³/h, intermediate between MSA 750 and MSA 1500, but with smaller connections (Ø 35 and Ø 50 mm vs. Ø 100 mm of the MSAs): it is optimized for grinders and sanders, not for large machines requiring Ø 100 mm. For workshops with a single bench grinder, the integrated solution is more ergonomic; for facilities with multiple machines, standalone MSAs are more flexible.
Krollit logistics and support
Bernardo shipping in 5-9 business days (7 days to the South). At 50 kg, it can be moved by one person or two with care. Nozzles, fan spare parts, and original Bernardo accessories available from stock with 3-5 business day shipping. Customer support available in Italian.
Who is the Model D with MSA 500 extraction system for
| Profile | Compatibility | Reason |
|---|---|---|
| Passionate hobbyist | Suitable | Interesting integrated solution for advanced hobby use. 400V three-phase required, and for occasional use, single-phase MSAs (MSA 300 at 230V) may be more practical. |
| Mechanical workshop with bench grinder | Recommended | Complete workstation: machine support + extraction + workpiece cooling. Ergonomic for daily use, reduces airborne dust in the workshop. |
| Sharpening / metalworking workshop | Recommended | Integrated water tank for workpiece cooling is a useful feature in sharpening: it improves finish and reduces overheating of cutting edges. |
Not suitable for: machines with Ø 100 mm extraction connections (standalone MSAs are correctly sized); workshops without a 400V three-phase line (consider MSA 300 at 230V single-phase); industrial production with large volumes of dust (1,275 m³/h capacity may be insufficient, consider MSA 1500 at 1,500 m³/h).

Frequently Asked Questions
Can I use it as an external extractor for other machines?
Theoretically yes, by connecting it via a flexible hose, but the Ø 35 and Ø 50 mm nozzles are different sizes from industrial standards (Ø 100 mm is typical). Custom adapters would be needed.
The Model D is optimized for integrated use with the machine resting on it. For external extraction on machines with Ø 100 mm nozzles, the standalone extractors in the MSA range are correctly sized. The advantage of the Model D is precisely its integration, not the flexibility of external connection.
What type of machines can be placed on the base?
Belt sanders and bench grinders of standard dimensions (machine surface within 400×285 mm). For larger machines, dedicated bases or custom supports are required.
Standard Bernardo bench grinders (SE, DSM range) have base dimensions compatible with the 400×285 mm surface of the Model D. For machines of other brands, check the base dimensions before purchasing. The base is designed for stable positioning of the machine above the extraction system.
Is the water tank for cooling really useful?
Yes, in sharpening and prolonged sanding operations. Water reduces the temperature of the workpiece, preventing overheating of the cutting edge (in sharpening) or thermal deformation (in sanding).
Water cooling is a standard technique for sharpening HSS or carbide cutting edges: without cooling, the heat generated by friction reduces the hardness of the material and accelerates wear of the cutting edge. For coarse sanding only, the water tank may not be necessary; for precision sharpening, it is important.
How much does the 0.37 kW motor consume?
Being a small motor, consumption is minimal: typically 0.3-0.4 kWh per hour of operation. For continuous use for an entire shift (8 hours), total consumption is about 2.5-3 kWh.
The electrical consumption of the Model D is practically negligible compared to the main machines in the workshop. 400V three-phase is mandatory: the motor is not interchangeable with single-phase motors. For workshops without a three-phase line, this is the main constraint.
Is the balanced fan really different from a standard one?
Yes. A statically and dynamically balanced fan does not generate vibrations during rotation, reducing noise, bearing wear, and vibration transmission to the machine above.
Balancing is a quality construction feature that distinguishes industrial fans from economic ones. On a base that supports a processing machine, an unbalanced fan would transmit vibrations that would worsen the finish of the machined part. Bernardo balancing is a choice for multi-year durability without maintenance interventions.
