In addition to the pro and con evaluation of air blasting and turbine lasting found in our previous blog, these two methods can also be compared in terms of throwing velocity, applications, and industries.
In terms of throwing velocity. Media thrown by turbines immediately start losing speed the moment that the turbine blade releases it, producing higher intensity blast results closer to the turbine. Larger shot retains its speed better over a distance and is commonly used to maintain intensity while creating a larger blast pattern by positioning the turbine(s) farther away. In contrast, media thrown by air nozzles will continue to accelerate for the first 100-300 mm outside of the nozzle depending on blast pressure and media size and density until the compressed air fully dissipates to the ambient environment, meaning that your best blast results occur a distance away from the nozzle.
