*Based on levels achieved in normal operating conditions with trained operators following procedures.

In a MICROVOID® clean containment system, HEPA filtered clean air pushes contaminated particles down and away from the operators breathing zone, providing ultra-clean breathing air. The contaminated air is then filtered and recirculated, eliminating the need to exhaust costly conditioned air.  Hazardous particles are captured within a "safe change" filtration system.  Fixed workstations and localized barriers are engineered into the system to facilitate productive working conditions and minimize operator mistakes.

MICROVOID® systems are engineered, constructed and tested under the highest quality control standards.  Materials of construction include stainless steel, cold rolled steel, safety glass and polymers. Filtration systems will be selected depending on the characteristics and volumes of materials being handled. Filter options include HEPA bag in/bag out, and charcoal filters.

MICROVOID® containment equipment ranges from low cost tabletop units to custom designed mini-environments. All models are flexible and can be portable. For over 40 years MICROVOID® has been designed with the reliability and performance characteristics that have made our units the recognized quality standard in this field!
