Features: 1. Convenient design: The smoke exhaust box is equipped with additional cable openings on the left and right sides, so the laser engraving cable or air-assisted cable is easier to pass through. There are also exhaust openings on the left and right sides. You can choose to install the fan and exhaust pipe on the left or right side according to the window position or actual use. The other side is glued with magic tape to ensure airtightness. 2. Isolation of smoke and odor & noise reduction: The closed design effectively isolates the smoke, burning odor and noise generated by the laser engraving machine. Protect your safety and health from smoke, noise and pungent odors, and provide a more comfortable indoor engraving environment. In addition, it can also be used as a dust cover to prevent the engraving machine from being covered with dust, and it is easy to store. Just wipe it with a damp cloth when cleaning. 3. Effective exhaust system and all-in-one design: The fan can effectively exhaust smoke through the duct (about 7.5cm in diameter and about 150cm in length) to keep fresh air indoors. The zippered viewing window is made of PVC, with a translucent design, and the built-in LED light tube makes it clear inside, which is convenient for observing the engraving progress. Note: Wear anti-blue light glasses to observe the engraving progress. 4.
