My dust collection system consists entirely of rigid pipe. Now I'm planning on getting CNC equipment. What should I be aware of regarding the flex hose for CNC equipment?
The flex hose recommended consists of a 30-mil urethane that is wire-reinforced. This urethane material has a high tear strength, and abrasion resistance to handle the chip collection required for such woodworking machines. The flex hose handles particleboard applications very effectively. It is also flexible enough to handle the stress of traversing back and forth on the moving equipment. For even more stressful, abrasive conditions, you can request a 45-mil urethane flex hose. It is not quite as flexible as the 30-mil material, but is considerably more durable. Applications for sawdust trailer loading, and leaf collection/street sweeping are its common practice.
