Who uses the MSA 300 and for what
The Bernardo MSA 300 is the entry-level dust extractor in the MSA family, sized for small artisan workshops with single-machine extraction needs. Its 15.6 kg weight and 230V single-phase power supply make it the most accessible and flexible choice in the range: it does not require a 400V three-phase line, can be used in any civil workshop, and is easily transportable by one person. The integrated mounting bracket allows direct attachment to a wall or machine, a useful solution in workshops with limited space. The single Ø 100 mm connection links one machine at a time, with an 870 m³/h airflow sized for bench grinders, standard belt sanders, and sharpeners. In Krollit customer workshops, it is chosen by advanced metal hobbyists, small artisan workshops, blacksmiths with a single workstation, and workshops without a three-phase line looking for a professional extraction solution.
Its place in the Bernardo range
The MSA 300 is the entry-level model in the Bernardo MSA extractor range, the only one in a 230V single-phase version. Above it are the MSA 750 (1,100 m³/h, 400V three-phase, dual connection, weight 36 kg) for intermediate professional use; and the MSA 1500 (1,500 m³/h, 400V three-phase, dual connection, 3-stage filtration, weight 72 kg) for intensive industrial use. The key difference of the MSA 300 is its flexibility: 230V single-phase power supply (compatible with any civil socket), reduced weight, integrated mounting bracket. The trade-offs: lower airflow (870 vs 1,100 vs 1,500), single connection (vs dual), no front drawer (vs MSA 750) or fine dust filters (vs MSA 1500). For workshops with a single machine and intermittent use, the MSA 300 is correctly sized. For continuous use or dual connection, upgrade to the MSA 750. For intensive industrial use, the MSA 1500.

Who the MSA 300 is for
| Profile |
Compatibility |
Reason |
| Passionate metal hobbyist |
Recommended |
Professional extractor in single-phase 230V version: compatible with any home workshop. Integrated bracket for wall mounting saves space. |
| Small artisan workshop / single blacksmith station |
Recommended |
870 m³/h airflow adequate for a bench grinder or single sander. 15.6 kg weight facilitates repositioning and maintenance. |
| Workshop without 400V three-phase line |
Recommended |
Only choice in the MSA range in 230V single-phase version. For workshops without three-phase, it is the available professional extraction solution. |
Not suitable for: simultaneous use on two machines (single connection, consider MSA 750 with dual connection); intensive continuous production (870 m³/h airflow may be insufficient, consider MSA 750 or MSA 1500); very fine dusts requiring 3-stage filtration (MSA 1500).

Frequently Asked Questions
Does it really work on any standard 230V household outlet?
Yes. The 0.75 kW motor draws peak currents manageable by a standard 3 kW civil meter. It works on a standard 16A socket without the need for an industrial line.
The MSA 300 is designed as a semi-professional extractor that combines industrial performance with domestic compatibility. For workshops with other machines running simultaneously, check the total power: the MSA 300 alone is manageable, but added to a bench grinder, it could approach the meter's limit.
Is the mounting bracket really practical?
Yes, for workshops with limited space. It allows the extractor to be fixed to the wall or the structure of the serviced machine, freeing up floor space.
Wall mounting is useful for fixed bench grinders: the extractor always remains close to the work point without cluttering. Fixing requires wall plugs appropriate for the wall (standard concrete is optimal; for plasterboard walls or light masonry, specific plugs are needed). The 15.6 kg weight is manageable by standard wall brackets.
What is the practical difference with the MSA 750?
The MSA 750 has an airflow of 1,100 m³/h (vs 870), a dual Ø 100 mm connection (vs single), a 400V three-phase motor (vs 230V single-phase), a removable front drawer (vs standard bag), and a weight of 36 kg (vs 15.6 kg).
For workshops without a three-phase line, the MSA 300 is the only choice in the range. For workshops with three-phase, the choice depends on use: single machine and intermittent use → MSA 300 (more economical and portable); two machines or continuous use → MSA 750 (superior performance). The price difference reflects the additional features of the MSA 750.
How long do the filter bags last?
In standard artisan use, filter bags last 100-300 operating hours before requiring replacement. This depends on the type of processing (fine dusts consume them more quickly).
The sign for replacement is a noticeable reduction in suction capacity. Original Bernardo filter bags are made of durable industrial fabric with good filtration efficiency for standard dusts. For very fine dusts (aluminum, pulverized cast iron), the MSA 300 with a single bag is not correctly sized; consider the MSA 1500 with additional fine dust filters.
Can I use the MSA 300 for more than one machine connected in series?
Technically yes, by using a Y-connector that divides the single connection into two, but the total airflow of 870 m³/h is divided between the two outlets (435 m³/h each). Result: less effective suction on both.
For simultaneous use on two machines, the MSA 750 with its native dual connection is recommended: each machine receives approximately 550 m³/h, more than double the solution with a Y-connector on the MSA 300. For alternate use of two machines (one at a time), the MSA 300 with a single connection is sufficient: you disconnect from one and connect to the other.
