Electronic Cleanroom Fan Filter Unit (FFU) Uses HEPA Filters To Remove Airborne Contaminants

Our FFU cleanroom solution features a high-performance HEPA fan filter unit (FFU) designed as a modular ceiling-mounted system for laminar flow cleanrooms. This fan filter unit integrates a built-in fan and FFU HEPA filter to deliver ISO Class 5 (Class 100) to ISO Class 8 (Class 100,000) cleanliness levels. The flexible design allows seamless integration with any cleanroom ceiling grid, making it ideal for semiconductor fabrication, pharmaceutical compounding, electronics assembly, and biotechnology labs where airborne contamination control is critical.

Key Benefits of HEPA FFU Technology

• Superior Air Filtration: The HEPA FFU captures 99.99% of particles ≥0.3 μm, ensuring ultra-clean airflow for sensitive processes.

• Energy-Efficient Operation: DC motor variants consume up to 30% less power than traditional AC models while maintaining 0.45 m/s uniform velocity.

• Low Noise & Vibration: ≤55 dB and ≤1.4 mm/s vibration for operator comfort in GMP cleanrooms and microelectronics clean rooms.

• Modular Scalability: Connect multiple fan filter units in series to create 100-level laminar flow zones or full cleanroom ceilings.

Applications & Installation of HEPA Fan Filter Unit

The HEPA fan filter unit supports modular deployment in:

• Cleanroom FFU ceilings for ISO 14644-compliant environments

• Dust-free workbenches and laminar flow hoods

• Pharmaceutical aseptic filling lines and USP 797 compounding in pharmaceutical cleanrooms

• Microelectronics wafer fabs and PCB assembly

• Hospital isolation rooms and biosafety cabinets

• Units can be daisy-chained for 100-level laminar flow pipelines or installed individually above critical zones. Compatible with clean transfer cabinets, clean sheds, and storage closets.

  
  

Construction & Components of HEPA Fan Filter Unit

• Housing: Stainless steel, aluminized zinc, or cold-rolled steel – lightweight, corrosion-resistant, and aesthetically refined for FFU cleanroom aesthetics.

• Fan: German EBM direct-drive centrifugal blower with >50,000-hour MTBF, stepless speed control, and maintenance-free bearings.

• FFU HEPA Filter: Gel-seal or knife-edge H14 HEPA (99.995% @ MPPS) with aluminum frame and PTFE gasket for zero bypass leakage.

• Airflow Pattern: Top intake → primary filter → HEPA FFU → uniform 0.45 m/s downward laminar flow across entire outlet face.

Why Choose Our Fan Filter Unit?

Ranked among the quietest and most cost-effective fan filter units on the market, Wiskind HEPA FFU delivers:

• Lower lifecycle costs via DC motor efficiency and long-life components

• Reduced downtime with hot-swappable filters and tool-free access

• Compliance with FDA, EU GMP Annex 1, and IEST-RP-CC002 standards

• Easy retrofitting into existing cleanrooms without structural modifications

Perfect for facilities upgrading from traditional cleanroom HVAC to decentralized FFU cleanroom systems for better energy management and zonal control.

The FFU fan filter unit can be connected and used in a modular manner. The FFU fan filter unit is widely used in clean rooms, dust-free operation tables, dust-free production lines, assembled clean rooms and local hundreds of applications. The FFU fan filter unit can be used Simple clean workbench, clean shed, clean transfer cabinet and clean storage closet, etc.

It can be arranged as a single unit according to process requirements, or multiple units can be connected in series to form a 100-stage assembly line. The shell structure is made of stainless steel, aluminized zinc panel, and cold-rolled steel panel, which is light in weight, corrosion-resistant, rust-proof, and beautiful.

The fan sucks in the air from the top of the FFU and filters it through the primary high-efficiency filter. The filtered clean air is sent out at an average speed of 0.45m/s on the entire air outlet surface. The fan adopts German EBM, which has the characteristics of long life, low noise, maintenance-free, low vibration, and stepless speed regulation. The fan is of reliable quality and has a working life of more than 50,000 hours.

The fan filter unit is one of the quietest and most expensive units on the clean market. With this unit, high-quality air can be delivered to the clean room. And the air flow shape is good, it is suitable for semiconductor, electronics, flat panel display and disk drive manufacturers and optical, biological industries and other industries to be used in clean rooms, clean workbenches, clean production lines, assembled clean rooms and local 100-level occasions and Other places with strict control requirements on air pollution have low energy consumption and lower operating costs.
