Terminal End Diffusers

Terminal end diffusers are a critical component in ceiling-mounted cleanroom HVAC systems. Designed to house HEPA or ULPA filters, these diffusers distribute filtered air into the cleanroom while ensuring even airflow and compliance with ISO and cGMP standards. Ideal for ISO Class 7–8 environments, terminal end diffusers are a compact, cost-effective alternative to fan filter units in controlled environments.

Terminal_HEPA Filter Diffuser

Terminal Diffusers ULPA and HEPA air filter modules are designed to provide unidirectional airflow from tee-bar ceilings. Standard air filtration modules come in 24 in. x 24 in. and 24 in. x 48 in. sizes with either 10 in. or 12 in. diameter collars. The HEPA air filter efficiencyour is rated at 99.99% at 0.3 microns and the ULPA air filter efficiency is rated at 99.9995% at 0.12 microns. HEPA cleanroom air filters are available in three filter pack depths: 53, 70, and 100 mm.
