E-Series free-standing polypropylene ductless fumehoods from AirClean Systems fit a variety of applications and come in three models: AC3000E (36 in.), AC4000E (48 in.), and AC6000E (72 in.). The off-the-shelf containment solutions eliminate the need for costly customization when enclosing mixers, mills, grinders, reactors, or other tall equipment. Typically floor mounted, the enclosures feature an upper folding sash combined with lower access doors, providing easy ergonomic access during manipulation. The enclosures pull room air through the back baffle and filter chemical fumes, vapors, and particulate via bonded carbon and/or HEPA filtration before returning clean air to the room. www.aircleansystems.com; tel.: 800-849-0472
