Zortrax HEPA Cover is an air filtering device compatible with Zortrax M200 and Zortrax M200 Plus 3D printers. Moreover, it keeps the temperature stable inside the build chamber. This reduces warping when you work with ABS-based materials. Built-in carbon filter gets rid of unpleasant odors released in the 3D printing process while HEPA filter catches over 99% of 3D printing emissions, including ultra-fine particles.
