The Simplex SIS 212 Modular Frame System provides a wide variety of enclosure solutions for cleanrooms, dust control, sound control, safety and other industrial applications. The system is designed for fast construction and can be easily customized. Enclosures can be fitted with HEPA filters and modular air conditioning units, or can be quickly adapted to existing ventilating and dust collection systems.

The Simplex SIS Modular Frame System is built around simple, strong, easy to assemble modules. You can quickly assemble three or four sided modular sections and latch or screw them together. It's that simple! Modules can be disassembled or expanded as your needs change.

Outfit the SIS 212 enclosure with optional casters and you have an enclosure you can move around the shop floor wherever you need to guard a process from contamination.
