We create innovative engineering solutions and implement them in projects that benefit a variety of industries. Our advanced engineering services, including Digital Manufacturing, Optimization Analysis and Design for Assembly, are meticulously designed to provide efficient and sustainable solutions and results over long periods of time.

We also believe it is the quality of advice that makes us different.. whether that advice is around the type of abrasive needed for your needs, or a task specific engineering solution we are here to help.



W Granowski is Australia's foremost expert in surface preparation technologies, supplying abrasive blast equipment, consumables, and degreasing equipment to suit a wide range of industrial applications.  


We produce both wet and dry air blast machines for use with bead or "sand", and airless (wheel) shot / grit blast machines for surface preparation of product - whatever the size, shape, or condition. We also produce a range of robust hot wash degreasers for cleaning oily and contaminated parts, large and small.


Our machines are designed and manufactured in our Melbourne facility and comply with all Australian design and safety standards.


Our experience sets us apart. W Granowski has designed and manufactured thousands of machines, across all industry segments, for both the domestic and overseas markets. With 95% of our customers providing repeat business we pride ourselves on our customer satisfaction and service.



W Granowski manufactures standard air blast cabinets for blasting, finishing, peening and cleaning. Our machines include suction machines for dry and wet blasting, and pressure fed machines for heavy duty or automated work.


Our specialty is custom built equipment. We can adapt or remodel a standard machine – such as a wet blast cabinet with a custom designed loading mechanism. Or design and manufacture for special purpose – such as to blast carbon fibre.

Typical Applications:

  • Cleaning

  • Corrosion removal

  • Deburring and deflashing

  • Mould and die cleaning

  • Paint stripping

  • Rust and heat scale removal

  • Peening

  • Surface texturing (e.g. etching / frosting glass)

  • Polishing (e.g. removing CNC machining marks from aluminium parts)



As the foremost expert in airless or wheel blast surface preparation in Australia, W Granowski has an extensive range of wheel blast machines to handle product of any size and shape. Whether the environment is high volume mass production or low volume jobbing-shop, we work with each customer to identify the abrasive blast solution that best suits the application. Our trademark robust build and machine reliability is key to our success.  


All our wheel blast equipment is designed for ease of maintenance and low running costs. Our long life blast wheels and wheelhouse liners are simple to replace.

Cast cabinet liners are utilised for grit or cut wire blast or peen, or heavy duty applications.

The abrasive reclaim and airwash separation system removes contaminants before feeding the clean abrasive back to the blast wheel. A self-cleaning dust extraction system ensures airborne particles are removed.

Airless blast equipment is suitable for blasting any metallic surface using metallic abrasive such as carbon steel or stainless steel shot or grit, chilled iron grit or cut wire.

Typical Applications:
• Rust Removal

• Concrete Texturing

• Coating Removal

• Deflashing

• Mill Scale Removal

• Etching

• General Steel Preparation

• Peening

• Profiling

• Sand Removal



W Granowski stocks standard parts for Granowski, Wheelabrator and Tilghman machines at its main warehouse in Victoria. Non standard parts are made to order. All original drawings and machine files have been maintained and we can supply machine parts for equipment as old as 55 years.


As the Australian distributor of W Abrasives' premium brand "Thomas Abrasives", stock of carbon steel shot and grit is held in warehouses nationally.


We are the national supplier of premium quality Ervin stainless steel shot Amacast, stainless steel grit Amagrit and hold stock in the Victorian warehouse.

We source locally manufactured glass bead and garnet, and supply mineral and plastic abrasive for specific applications.
