The Applied KB50 Wet Blast Attachment is designed to inject a water supply directly into the blasting air stream immediately prior to entering the blast nozzle. This greatly reduces dust levels by up to an amazing 95%. This attachment requires a high pressure hydraulic pump to overcome the air pressure within the blast hose. This remarkable product does not effect the blast efficiency ideally suited for jobs in metropolitan areas or jobs where excessive dust is generated. The KB50 can be used with a water and rust inhibitor mix to be sprayed through the head during blasting. When the air/abrasive stream passes the attachments, water atomizes to envelop the abrasive particles and the water volume is fully adjustable using the petcock valve.
