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. |
