Class I and HEPA Filtered Enclosures

Purifier Class I Safety Enclosures and Purifier HEPA Filtered Enclosures protect you and your laboratory environment. They offer an economical alternative to Class II laminar flow cabinets when your applications do not require product protection.

Purifier Class I Enclosures protect the user from agents that require Biosafety Level 1, 2 or 3 containment but no product protection. These enclosures include an ultraviolet light that may be used in conjunction with surface disinfection to ensure thorough decontamination.

Purifier HEPA Filtered Enclosures, which do not include a UV light, protect the user from hazardous chemical powders, dust and allergens in diverse applications ranging from screening suspicious mail to weighing drug ingredients.
