Cleanroom Equipment

Positioning

Cleanroom equipment maintains the controlled airflow and contamination control required for ISO-classified cleanrooms. Fan filter units generate ceiling-down laminar airflow, while biosafety cabinets, air showers and pass boxes handle the entry, handling and transfer of materials and personnel.

What it is

Cleanroom equipment maintains the controlled airflow and contamination control required for ISO-classified cleanrooms.

Technical depth

Fan filter units (FFU) combine a fan with a HEPA/ULPA filter in a galvanised or stainless housing; a 48"×48" double-motor unit delivers 4000–5000 CMH at Class 100. Efficiency runs F8/F9 (EN 779) through H10–H14/U15 (EN 1822), with 80 °C / 80% RH operating limits. The range extends to laminar-flow cabinets, biosafety cabinets, air showers and pass boxes. The sizing logic runs from the room, not the unit: the cleanroom ISO class dictates the airflow and coverage, and the FFU fleet is sized to hold it. Air showers remove particulate from personnel at entry, while pass boxes transfer materials without breaking the barrier, and both must be specified together with the ceiling FFU system to hold the target class end-to-end. AC motors suit small fleets, while EC motors suit fleets over a hundred units where central control and energy efficiency justify the premium.

Selection guidance

• Confirm the cleanroom ISO class and required FFU airflow/coverage.
• Specify AC or EC motor and voltage (110/220 V).
• Confirm dimensions and whether standard or custom sizing is needed.

Procurement notes

• Confirm the cleanroom ISO class and the FFU airflow/coverage required to hold it.
• Specify AC versus EC motor and voltage (110/220 V); EC suits fleets over 100 units with central control.
• Confirm dimensions and whether standard or custom sizing is needed.

From a sourcing perspective

From a sourcing perspective, cleanroom equipment should be designed as a system, not bought as individual units. We recommend starting from the cleanroom ISO class and working back to the FFU airflow and coverage required to hold it, then specifying AC versus EC motor and voltage — EC suits fleets over a hundred units where central control is needed. Our advice is to size the fleet to the room rather than matching dimensions alone, and to specify entry and transfer equipment such as air showers and pass boxes together with the ceiling FFU system, because omitting them undercuts the cleanliness the ceiling is trying to hold. Design the air chain end-to-end rather than specifying the HEPA filter alone. Specify AC versus EC motor and voltage, since EC suits larger fleets where central control and energy efficiency justify the premium.
