Description
Cleanroom FFU Replacement and Specification Matching
This page supports replacement and project matching for complete fan filter units used in cleanrooms and controlled environments. The selected unit must match the ceiling or equipment opening, airflow duty, available static pressure, power supply and required filter class.
Configuration review
Available configurations may use galvanized steel, aluminum or stainless-steel housings with pleated glass-fiber filter media. HEPA class, efficiency, airflow and operating limits must be confirmed from the selected model and applicable test report. The legacy H11–H14/EN 779 wording and fixed 250°C claim are not used as general specifications.
