Abrasive media, dust and removed contamination are drawn back into the main body through the attachment sealed against the surface. Cyclonic separation returns reusable abrasive media through a screen to the hopper, while dust and lighter residues are collected in the dust bag.\u003c\/p\u003e\u003chr\u003e\u003ch5\u003eTwo-Stage Control Lever\u003c\/h5\u003e\u003cdiv style=\"line-height:1.75;\"\u003e✔ Lever partially operated: extraction only\u003cbr\u003e✔ Lever fully operated: blasting and extraction simultaneously\u003cbr\u003e✔ After blasting, keep the lever in the extraction position for another 2 to 3 seconds\u003cbr\u003e✔ Residual abrasive media and dust are drawn back from the blast head\u003c\/div\u003e\u003chr\u003e\u003ch5\u003eAttachments, Adapters and Brushes\u003c\/h5\u003e\u003cp\u003eThe EDUCT-O-MATIC can be adapted to the workpiece geometry using different attachments.
