Description: StealthMax is an air filter developed specifically for 3D printers. It uses activated carbon and HEPA filters, designed to filter and absorb harmful fumes and unpleasant odors generated when plastics are melted, creating a and more comfortable environment for users, purifying the air and protecting health. It is also equipped with a HEPA (High Efficiency Particulate Air) filter, which can effectively capture tiny particles with a diameter of 2.5 Micrometres and below (usually much smaller in 3D printing) and filter the tiny particles generated during the printing process. The use of for W Wifi wireless module makes installation and operation simpler and more convenient. Add a 12V step-down module. The device can be directly powered by 24V without a separate 12V power supply. Each module has been soldered with pin headers and circuits, and can be plugged in and used directly without re-soldering. Scope of application: most machines Required bed size:300x300 (StealthMax) Notes: 1) Activated carbon filter material, determine whether to replace the filter material based on the filtration efficiency; 2) HEPA high-efficiency filter: determine whether to replace the filter based on the air output (actually, determine whether to replace it based on the wind resistance, and there is no such measurement function in the module). Specifications: Due to different batches, there may be differences in product appearance and printed text, which not affect use Color: as shown Material: Plastic + Metal Package Contents: 1 * Air Purifier kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
