Choosing the Right Clemco Low-Pressure Blasting Machines
Clemco low-pressure blast machines are suitable for applications in which sensitive surfaces need to be processed in a controlled manner. The key factor here is not just low operating pressure, but the interplay between blasting pressure, abrasive media, nozzle size, air supply, and material.
Typical Applications
✔ Restoration and historic preservation
✔ Facade and Natural Stone Cleaning
✔ Wood and Brick Processing
✔ Graffiti and coating removal
✔ Gentle metalworking
Match working pressure to the abrasive media
A low operating pressure reduces mechanical stress on the surface. At the same time, the shape, size, and hardness of the abrasive media significantly influence the result. For sensitive substrates, you should therefore always start with the most moderate parameters possible and adjust the settings gradually.
Air Demand and Nozzle Size
Even with low-pressure blast machines, air demand increases as the nozzle bore diameter and operating pressure rise. The compressor must therefore not only reach the desired pressure but also be able to continuously supply the required air volume.
Here’s what you should look for when making your selection
✔ Material and surface sensitivity
✔ Desired pressure range
✔ Abrasive media and grain size
✔ Nozzle bore diameter and compressor power
✔ Mobility and tank size
✔ Desired complete equipment package
FAQ
Are low-pressure blast machines only suitable for very low pressures?
No. The key factor is the available control range. This allows a device to be used for both particularly gentle applications and more powerful blasting operations.
Which abrasive media are suitable for sensitive surfaces?
That depends on the substrate and the desired result. In addition to hardness and grain shape, grain size and working pressure are also crucial.
Can I operate a low-pressure blasting machine with any compressor?
No. The compressor must be capable of supplying the air volume required for the nozzle and operating pressure.
Advice on Clemco low-pressure blast machines
Information regarding the surface, desired blasting result, abrasive media, nozzle size, and available compressed air supply will help you make your selection.
