Bernardo SB 3 Sandblaster with Extractor and Filter
The Bernardo SB 3 is a professional sandblaster with an integrated extractor and filter, designed for the cleaning and satin finishing of metal surfaces. It uses a pressurized flow of dry abrasive particles — such as glass beads or abrasive grit — to remove oxidation, paint residues, or impurities, restoring a uniform surface to the metal, ready for painting or treatment. The process takes place in a closed cabinet with a large transparent screen, allowing safe monitoring of the operation. Equipped with internal lighting and a foot pedal for air control, it offers precise control during sandblasting. It can be connected to an external air compressor or a centralized system. Robust, compact, and safe: suitable for workshops, body shops, and mechanical laboratories.

Frequently Asked Questions
What is the difference between SB 1, SB 2, SB 3, and SB 4?
SB 1: the most compact (benchtop cabinet for hobbyists, small volume, no integrated extractor). SB 2: professional benchtop cabinet, larger volume, integrated lighting. SB 3: like SB 2 with integrated extractor and filter — no external extractor required. SB 4: the largest (148 liters), for large workpieces, with integrated extractor. The choice depends on the volume of the pieces and frequency of use.
What type of abrasive material is used?
Bernardo SB 1–4 cabinets use dry grit: glass beads (for shiny surfaces), white or brown corundum (for roughing and satin finishing), garnet (for aluminum and soft materials), glass pearls (for finishing). Each abrasive leaves a different surface finish. The most common grit size is 80–120 mesh for general use. Do not use quartz sand — it produces silica dust which is dangerous for health.
Does the SB 3 / SB 4 cabinet require an external extractor?
No. SB 3 and SB 4 have integrated extractors and filters — they operate autonomously without connection to an external extractor. SB 1 and SB 2 require connection to an external extractor for air recirculation and dust filtration.
Are spare nozzles and films available?
Yes. Ceramic nozzles (Ø 4, 5, 6, 7 mm), protective films for the viewing window, and all original Bernardo spare parts are available with 3–5 business days shipping.
What compressor is needed for SB cabinets?
Bernardo SB 1–4 cabinets require compressed air at 5–8 bar. A compressor with a minimum 50-liter tank and a minimum flow rate of 200–300 l/min is adequate for intermittent use. For continuous use, prefer compressors with a higher flow rate — sandblasting is an operation with high air consumption.
