Fan Filter Units (FFU) — HEPA & ULPA Modules

ADS Laminaire manufactures fan filter units (FFU) — self-contained HEPA or ULPA filtration modules that deliver clean, unidirectional airflow. FFUs are the building block of modular cleanroom ceilings and laminar flow systems.

Our FFUs use energy-efficient ECM motors with automatic flow regulation, maintaining constant airflow as filters load over time.

Our Range

Standards & Certifications

FFUs deliver HEPA H14 (≥99.995%) or ULPA filtration and are sized to achieve the required ISO 14644-1 class for your cleanroom. ECM motor control maintains constant velocity and reduces energy consumption.

Units are available in standard cleanroom grid sizes for easy integration.

Applications & Industries

FFUs are used in modular cleanroom ceilings, laminar flow workstations, mini-environments and retrofit projects. See our modular cleanrooms for complete systems.

Frequently Asked Questions

What is a fan filter unit?
A fan filter unit (FFU) is a self-contained module combining a fan and a HEPA or ULPA filter, delivering clean unidirectional airflow. FFUs are used in cleanroom ceilings and laminar flow systems.
What is the benefit of an ECM motor?
ECM (electronically commutated) motors are highly energy-efficient and maintain constant airflow automatically as the filter loads, reducing running cost and manual adjustment.
What filtration efficiency do your FFUs provide?
Our FFUs are available with HEPA H14 (≥99.995% at MPPS) or ULPA filtration depending on the ISO class required.
