Holzmann SK220_230V Sandblasting Cabinet: 220-Litre Capacity for Metal Cleaning and Surface Preparation

The Holzmann SK220_230V sandblasting cabinet is a workshop machine designed for various abrasive blasting, rust removal, cleaning and metal surface preparation operations.

With its 220-litre working capacity and support grid capable of holding a maximum load of 60 kg, this enclosed blasting cabinet allows a wide range of mechanical components to be treated in a controlled working area.

It is particularly suitable for mechanical workshops, metalworking professionals, repair technicians, restoration specialists and users looking for equipment designed for blasting small and medium-sized parts.

Abrasive blasting inside a cabinet involves projecting blasting media onto the surface of a workpiece using a gun powered by compressed air.

This process can help remove certain types of corrosion, old paint coatings, surface deposits and other contaminants.

The Holzmann SK220 therefore provides a practical solution for preparing metal components before restoration, repainting or further finishing operations.

A 220-Litre Sandblasting Cabinet for Workshop Applications

The Holzmann SK220 sandblasting cabinet offers an internal working capacity of 220 litres, allowing components of different shapes and sizes to be treated.

Its lid features an 860 x 410 mm opening, making it easier to insert and remove workpieces.

The cabinet is fitted with a support grid designed to hold components during the blasting process.

This grid has a maximum load capacity of 60 kg, allowing relatively heavy parts to be handled, provided their dimensions are compatible with the available working space and their weight is properly distributed.

This capacity can be particularly useful for cleaning mechanical components, metal brackets, dismantled automotive parts and various items requiring restoration.

The size of the workpiece should always allow enough room to handle the blasting gun safely and effectively inside the cabinet.

Rust Removal and Paint Stripping from Metal Parts

The Holzmann SK220_230V sandblasting cabinet is particularly suitable for abrasive cleaning and stripping of metal surfaces.

Over time, mechanical components and metal structures may develop different types of surface deterioration, including:

• Rust and oxidation.

• Old paint coatings.

• Dirt and surface deposits.

• Deteriorated protective coatings.

• Surface imperfections requiring preparation before finishing.

Abrasive blasting works by directing a stream of abrasive particles against the surface of the workpiece.

Depending on the blasting media, working pressure and material being treated, this process can remove certain coatings and produce a cleaner surface.

The Holzmann SK220 sandblasting cabinet can therefore be used when restoring metal parts before repainting or applying protective coatings.

However, the blasting process must be carefully adapted to delicate materials and surfaces requiring a specific finish.

Metal Surface Preparation Before Painting and Coating

Abrasive blasting of metal components is also commonly used to prepare surfaces before finishing operations.

By removing contamination and deteriorated coatings, blasting helps produce a surface suitable for subsequent preparation and treatment.

Depending on the abrasive selected, the process may also create a surface profile that improves the adhesion of certain coatings.

This type of treatment can be useful before:

• Painting metal components.

• Applying selected protective coatings.

• Restoring mechanical parts.

• Refurbishing metal brackets and supports.

• Performing certain anti-corrosion treatments.

To achieve satisfactory results, it is important to choose blasting media compatible with both the workpiece material and the intended finishing process.

After blasting, the workpiece should also be properly cleaned to remove residual dust and abrasive particles before applying a coating.

Compressed-Air Sandblasting Gun

The Holzmann SK220_230V operates using a sandblasting gun powered by an external air compressor connected to the cabinet.

The manufacturer specifies the following operating requirements:

• Operating pressure: 4–8 bar.

• Compressed-air consumption: 200–350 litres per minute.

• Air connection: 1/4-inch European type.

These specifications are essential when selecting a compressor capable of supplying the cabinet correctly.

Checking the compressor's maximum pressure alone is not sufficient. Its actual delivered airflow must also be compatible with the requirements of the blasting gun.

Insufficient airflow can reduce blasting performance and make the cleaning process slower or less consistent.

For regular use, choosing a compressor with an adequate continuous air delivery capacity is recommended.

Please note: the air compressor is not included with the sandblasting cabinet.

Four Ceramic Blasting Nozzles Included

The Holzmann SK220 sandblasting cabinet is supplied with several ceramic nozzles, allowing the blasting gun to be adapted to different applications.

The included nozzle diameters are:

• 4 mm ceramic nozzle.

• 5 mm ceramic nozzle.

• 6 mm ceramic nozzle.

• 7 mm ceramic nozzle.

Nozzle diameter influences compressed-air consumption and the characteristics of the abrasive jet.

The choice of nozzle should therefore take into account the available compressor, the type of workpiece and the blasting operation.

A larger nozzle may require greater airflow to maintain suitable working conditions.

Ceramic nozzles are wear components because abrasive particles continuously pass through them.

Regular inspection is recommended, and worn nozzles should be replaced when their condition affects blasting performance.

Which Blasting Media Should Be Used with the Holzmann SK220?

Selecting the correct abrasive is essential for achieving good results with a sandblasting cabinet for metal parts.

The manufacturer specifies an abrasive grain size of 0.12–0.25 mm.

The cabinet accepts a maximum abrasive quantity of 32 litres.

Different types of blasting media may be suitable, provided they are compatible with the machine, its specified grain size and the material being treated.

The selection should take into account:

• The hardness of the surface.

• The level of rust or contamination.

• The presence of existing coatings.

• The required surface finish.

• The compatibility of the blasting media with the cabinet.

For sensitive materials, it is advisable to test the selected abrasive on a small, inconspicuous area before treating the entire workpiece.

Blasting media are not included in the delivery.

Only use blasting media approved for this type of equipment. Ordinary silica sand must not be used as blasting media because inhaling respirable crystalline silica dust can cause serious health problems.

Integrated Protective Gloves for Handling Workpieces

The Holzmann SK220_230V sandblasting cabinet features two openings designed for protective gloves.

Each glove opening has a diameter of 175 mm.

The gloves are attached to the cabinet, allowing the operator to handle workpieces and the blasting gun without placing bare hands inside the abrasive blasting area.

This design makes blasting operations easier while helping contain abrasive particles inside the enclosure when the cabinet is properly closed.

It also improves working comfort when cleaning mechanical components.

The gloves should be inspected regularly for tears, holes and signs of wear.

The cabinet must always be operated according to the manufacturer's safety instructions, with appropriate dust extraction or filtration and the necessary personal protective equipment.

Internal Lighting for Improved Visibility

The Holzmann SK220 is equipped with an internal lighting system that helps the operator see workpieces during blasting operations.

This lighting makes it easier to observe surfaces and position the blasting gun accurately.

It is particularly useful when treating hard-to-reach areas, corners or components with complex shapes.

The electrical supply specified for the machine is 230 V / 50 Hz.

It is important to distinguish this electrical supply, which powers the cabinet's electrical equipment, from the compressed-air supply required to operate the blasting gun.

An appropriate air compressor is essential for abrasive blasting.
