Criti-Clean™ FFU, 36" x 24", AJ Manufacturing (CAT#: STEM-C-0602-ZJF)

Criti-Clean™ FFU manufactured by AJ Manufacturing is a reliable fan powered laminar flow HEPA/ULPA filter diffuser for critical environments.
The unit combines vertical air mass laminar flow technology with ECM fan technology to provide a non-aspirating, low velocity, uniformly distributed downward moving "piston” of filtered air.
The unit provides a uniform airflow with high flexibility in clean environments in buildings where existing HVAC systems would typically cause constraints.
The unit can be customized for specific requirements.
