Abstract
A dry-ice blast device (A) includes an air compressor (2) of a low pressure type as a source of the compressed air, the delivery pressure being 1.2-2.5 atm. Dry-ice particle feeder (5), (6) is provided for mixing dry-ice particles (D) into the air flow in the air flow path upstream from a nozzle (32). This enables low pressure blasting, which suppresses the abrasion of the dry-ice particles (D), decreases the noise, reduces the overall size and weight of the device and makes easy the handling of the device.
