BFU

CLEANROOM AIR FILTRATION EQUIPMENT (BFU, FFU, HFU) - A STABLE AND HIGH-EFFICIENCY CLEAN AIR SUPPLY SOLUTION

In GMP-ISO cleanroom systems, air quality is a critical factor that directly affects product safety, process reliability, and overall manufacturing quality. BFU, FFU, and HFU cleanroom air filtration units (Fan Filter Units) are essential components that provide a continuous supply of clean air, effectively control fine particles and microorganisms, and maintain a stable cleanliness classification within the facility.

ACT Cleanroom - ACT International Technical Equipment Company Limited specializes in the design, manufacturing, and supply of BFU, FFU, and HFU systems that comply with cleanroom standards and are suitable for a wide range of industrial factory layouts in Vietnam.

What is cleanroom air filtration equipment?

BFU / FFU / HFU are integrated air filtration devices consisting of a fan and a HEPA filter, designed to perform the following functions:

• Purify incoming air.
• Supply clean air directly into cleanroom areas.
• Maintain room pressure and cleanliness levels in accordance with design.

➮ These units are typically installed on cleanroom ceilings, clean booths, operating theatres, and laboratory environments.

Differences Between BFU, FFU, and HFU

FFU  Fan Filter Unit

• Integrated fan and HEPA filter in a compact unit.
• Independently ceiling-mounted.
• Widely used in GMP cleanrooms and electronics manufacturing.
• Easy installation, operation, and maintenance.

BFU - Blower Filter Unit

• Higher airflow capacity compared to FFU.
• Connected to centralized ductwork systems.
• Suitable for large-area cleanrooms.
• Stable operation with improved energy efficiency.

HFU - High Efficiency Filter Unit

• Higher filtration efficiency.
• Designed for areas with stringent cleanliness requirements.
• Commonly applied in pharmaceutical, medical, and operating room environments.

Key advantages of ACT cleanroom air filtration equipment

Outstanding filtration performance

• Removes up to 99.99% of airborne particles ≥ 0.3 μm.
• Equipped with HEPA H13 / H14 filters.

Stable operation and energy efficiency

• High-quality motors.
• Low noise levels and long service life.

Cleanroom-compliant materials

• SUS 304 stainless steel or powder-coated steel.
• Smooth surfaces, low particle adhesion, easy cleaning and maintenance.

Operating principle of BFU / FFU / HFU

1. Ambient air is drawn into the filtration unit.
2. Air passes through a pre-filter to remove coarse particles.
3. Fine filtration is performed by the HEPA filter.
4. Clean air is evenly supplied into the cleanroom at the designed airflow rate.

➮ This process ensures uniform clean airflow distribution and minimizes the risk of particle recontamination.
