Why choose Gostol TST air blasting machines?
Depending on the customers' needs and requirements sandblasters come in a variety of sizes and styles. You can choose among two types of sandblasters: pressure sandblasters and suction (siphon) sandblasters. The main difference is in the purpose of use. Suction sandblasters are generally used light production jobs, and general cleaning of parts. Pressure blasting is significantly faster and more aggressive than suction blasting.
Suction (siphon) sandblasters
- Lower initial cost: Suction sandblasters cost less, because you need less equipment than with a pressure sandblasters.
- Lower operating costs: The media leaves the blast nozzle at a lighter pressure and speed, which means less wear of replacement parts of the machine.
- Lower air volume requirements: Suction sandblaster uses less air compared to pressure sandblaster with a comparable blast nozzle size.
- High production: Pressure blasting is 3 - 4 times faster than siphon blasting.
- Better cleaning ability: With pressure blasting you can blast workpieces that have a greater degree of surface contamination.
- Can be used with metallic medias: If you would like to achieve certain surface profile, sometimes metallic medias need to be used. Heavy metallic medias are not suitable for siphon blasting.
Sandblasters are used for:
- Cleaning of impurities
- Hardening, shot peening
- Grazing for esthetical purposes
- Paint removal
- Surface preparation for application of colours, rubber, etc.
