01Define the mounting location and available ceiling or equipment envelope.
02State the required filter class and whether molecular filtration is also needed.
03Confirm available power, local or network control and monitoring expectations.
04Provide airflow, external resistance, noise and material constraints for selection.
How to Select Fan Filter Units
Start with the operating task and site constraints, then compare the product direction that best matches the intended use.
| Buyer requirement | Product direction | Why it helps |
|---|---|---|
| General modular ceiling supply | Standard, AC or EC Fan Filter Unit | Balanced ceiling-grid integration with replaceable final filtration. |
| Limited ceiling void | Low-Profile Fan Filter Unit | Shallow housing reduces required plenum depth. |
| Higher system resistance | High-Static-Pressure FFU or BFU | Deeper blower arrangements maintain airflow against added resistance. |
| High air volume from one bay | High-Airflow Fan Filter Unit | Large filter face and matched blowers serve demanding supply zones. |
| Ultrafine or molecular contamination control | ULPA FFU or AMC Chemical Filter FFU | Selects ultrafine media or a targeted adsorbent stage before final filtration. |
| Tool, mobile or localized integration | EFU, Mobile FFU, Floor-Standing FFU or Fan-Powered HEPA Module | Purpose-built formats place filtered air close to the process. |

23 models shown
AC Fan Filter Unit
A ceiling FFU built around a permanent-split-capacitor AC motor and local speed adjustment for individually balanced clean-air supply.
EC Fan Filter Unit
An electronically commutated fan filter unit for cleanroom installations that need adjustable motor speed and coordinated airflow settings.
Low-Voltage DC Fan Filter Unit
A low-voltage DC fan and final-filter module for equipment enclosures with a suitably matched power source and accessible filter servicing.
Low-Profile Fan Filter Unit
A shallow fan filter module for cleanroom ceilings and equipment spaces where the installed height and maintenance route need careful planning.
Low-Noise Fan Filter Unit
An EC-powered FFU for occupied cleanroom work areas, combining a vibration-isolated fan assembly with acoustic treatment in the upstream plenum.
High-Static-Pressure Fan Filter Unit
A deep-plenum FFU for cleanroom duties with added air-path resistance, combining a backward-curved EC fan, reinforced casing and pressure-test access.
High-Airflow Fan Filter Unit
A large-format FFU with two EC blowers and a broad final-filter face, bringing a twin-fan clean-air supply assembly into one reinforced ceiling housing.
Stainless Steel Fan Filter Unit
A stainless-enclosed ceiling FFU for facilities that need accessible metal surfaces and a filter-service arrangement suited to their cleaning routine.
Aluzinc-Coated Steel Fan Filter Unit
A ceiling FFU with an aluminium-zinc-coated steel enclosure for applications that favor a natural metallic casing rather than an all-stainless or painted exterior.
Explosion-Proof Fan Filter Unit
A hazardous-duty FFU built with a non-sparking blower, cast-metal motor enclosure, sealed electrical path and grounded filter frame for clean areas handling flammable vapors or dusts.
ULPA Fan Filter Unit
A ceiling fan filter module for particle-sensitive processes, with the ULPA filter, perimeter seal and fan operating point selected as one assembly.
AMC Chemical Filter FFU
A fan filter assembly combining target-specific molecular media with a separate particulate stage for contamination-sensitive process air.
Side-Discharge Fan Filter Unit
A vertical fan filter cabinet that delivers clean-air supply horizontally at process level when an overhead module is unsuitable.
Floor-Standing Fan Filter Unit
A fixed-position horizontal-air FFU on a freestanding frame for particle-sensitive work beside existing benches and equipment.
Mobile Fan Filter Unit
A wheeled filtered-air cabinet that can be repositioned between particle-sensitive workstations and secured for use at the selected location.
Blower Filter Unit (BFU)
A ceiling supply assembly combining a centrifugal blower, a duct-entry housing and a downstream particulate filter in one module.
Equipment Fan Filter Unit (EFU)
A compact fan-and-filter assembly for equipment builders who need a defined clean-air outlet, mounting pattern and electrical interface inside a process tool.
Cleanroom Recirculation Air Unit (RCU)
A local return-air cabinet for recirculating filtered room air, with a cooling-section option when the clean zone also needs removal of equipment heat.
Fan-Powered HEPA Module
A ceiling supply module that combines its own fan with a replaceable HEPA filter, useful where terminal filtration needs local airflow adjustment and accessible servicing.
STJH 400 x 400 mm Compact EC Fan Filter Unit
A compact 3 m³/min HEPA supply module for equipment housings with limited roof space.
STJH 500 x 500 mm EC Fan Filter Unit for Assembly Enclosures
A mid-size filtered-air module that expands coverage while retaining a low 185 mm overall height.
STJH 610 x 610 mm High-Flow EC Fan Filter Unit
The highest-flow square format in this three-model group, intended for larger equipment enclosures.
No models match every selected filter.

Solutions for Your Application
Overcome the Challenges in Your Process
Make better use of your ceiling space and get the clean-air supply your process needs. We help you select an FFU around airflow resistance, noise, filtration and maintenance access, with control options for individual units or coordinated zones.
The ceiling void is too shallow for a conventional unit.Compare low-profile or equipment-integrated formats against the available envelope.
Airflow falls as filters load or duct resistance increases.Evaluate high-static or BFU arrangements using the actual external-resistance requirement.
Local noise disrupts occupied work areas.Use a low-noise configuration and coordinate operating setpoint and mounting isolation.
The process needs ultrafine or molecular contaminant control.Specify ULPA media or an AMC adsorbent stage according to the identified contaminant.
Multiple units must operate as a coordinated zone.Select EC-compatible controls and link to the dedicated controls and ceiling-components family.
Tell Us What Your Application Needs
- Room and process application

- Local, group or BMS control requirement
- Housing material and service-access direction
Plan Your Cleanroom Equipment Together
Before choosing Fan Filter Units
AC models suit straightforward local operation, while EC models are commonly selected when variable control, lower operating demand or network monitoring is needed. Final selection depends on the project control strategy.
Many housings can be configured around an appropriate HEPA or ULPA final filter, but fan duty, seal arrangement and available pressure must be checked together.
Provide the mounting opening, required airflow, external resistance, filter requirement, room use, power supply and control method.
Available sizes, housing materials, filter seals, control interfaces and service arrangements can be coordinated around the intended application.
