Class 100 Clean Room Cabinet Ovens

For processes where eliminating particle contamination is required, such as sterilization, depyrogenation, curing and drying. These electrically heated ovens feature a low particle count Class 100 atmosphere inside. Exterior construction minimizes particle generation. Heavy duty units equally suited for pharmaceutical or industrial applications.

Class 100 Clean Room Cabinet Ovens Model Specifications:

CAUTION:  Ovens processing combustible material are required by National Fire Protection Association 86 Standard for Ovens and Furnaces (NFPA 86) to have a fire suppression system.  If flammable solvents or vapors are present in an oven, OSHA requires conformance with NFPA 86 Class A Oven requirements.  A powered forced exhauster and other non-standard safety equipment must be added.  See Class A Oven Equipment for Solvent Processing resource page, reference our FAQs or our contact us us for more information.
