FFU Fan Filter Unit is an air filter with integrated fan, providing clean air flow according to standards through HEPA or ULPA membrane, widely used in food factories. The latest price list below helps businesses easily choose the right FFU model, optimize dust and bacteria filtration efficiency .
1. General Information about FFU in the Food Industry
1.1. What is FFU?
FFU (Fan Filter Unit) is an air filtration device with an integrated fan used in cleanroom systems, designed to supply clean air that has been filtered through a HEPA or ULPA filter directly into the production area.
- Basic components: suction fan, filter (HEPA/ULPA), housing (powder-coated steel or stainless steel), speed controller.
- Main function: remove dust, bacteria, mold spores, and airborne particles.
- FFUs are typically installed on the ceiling of cleanroom areas or inside enclosed spaces such as clean booths.
1.2. Operating Principle of FFU
- Draws air from outside or from the cleanroom recirculation system.
- The fan pushes air through the HEPA or ULPA filter.
- The filter retains 99.97% (HEPA) or 99.9995% (ULPA) of ultra-fine particles.
- Releases clean air in either vertical (downflow) or horizontal (crossflow) direction, depending on the design.
Example: A standard HEPA FFU can filter 0.3-micron particles at ≥99.97% efficiency, ensuring production environments meet ISO Class 5-8 cleanliness levels.
1.3. Role of FFU in Air Quality Control in Food Plants
- Maintain sterile environments: Prevent microorganisms and dust from entering processing and packaging areas.
- Help control cross-contamination: Reduce risks of odor, dust, and microbial transfer between areas.
- Meet hygiene standards: Ensure particle counts in air comply with ISO 14644.
- Optimize productivity and product quality: Clean air extends shelf life and reduces defective products.
1.4. Applicable Standards: ISO 14644, HACCP, ISO 22000
- ISO 14644: Defines cleanliness levels based on particle count per cubic meter of air. FFUs are used to achieve ISO Class 5-8 in the food industry.
- HACCP (Hazard Analysis and Critical Control Points): Requires control of air quality at critical points such as packaging and mixing.
- ISO 22000: International standard for food safety management, requiring clean production environments to prevent contamination risks.
2. Structure and Classification of FFU
2.1. Main Components
A standard FFU consists of:
- Fan: Usually centrifugal or axial, used to draw and push air through the filter.
- HEPA or ULPA filter: Key component for removing fine particles and microorganisms.
- Housing: Protects internal parts, made from powder-coated steel or stainless steel for rust resistance and easy cleaning.
- Speed controller: Adjusts airflow for different zones.
- Pre-filter: Captures larger dust, protecting the main filter and extending its lifespan.
2.2. Classification by Size
Standard FFU sizes fit cleanroom ceiling grids:
- 2x4 feet (1175×575 mm): Suitable for compact spaces or modular clean booths.
- 3x4 feet (1175×875 mm): Balanced airflow and installation space.
- 4x4 feet (1175×1175 mm): For large airflow and high cleanliness requirements.
Note: Size directly affects airflow (CFM) and product cost.
2.3. Classification by Filter Type
- HEPA (High Efficiency Particulate Air):
- Efficiency: ≥99.97% @ 0.3 micron
- Applications: ISO 6-8, dry food packaging areas with low microbial load
- ULPA (Ultra Low Penetration Air):
- Efficiency: ≥99.9995% @ 0.12 micron
- Applications: ISO 4-5, sterile food processing, perishable products
2.4. Classification by Housing Material
- Powder-coated steel: Affordable, corrosion-resistant, easy to manufacture. Not ideal for wet or corrosive environments.
- Stainless steel 304: Corrosion-resistant, easy to clean, durable in harsh environments, but more expensive.
2.5. Optional Features & Upgrades
- Automatic fan speed control (EC motor) - saves energy, reduces noise
- Anti-static (ESD) protection - for static-sensitive environments
- Pressure and airflow sensors - monitor filtration performance in real time
- BMS connectivity - control multiple FFUs from a central system

3. Factors Affecting FFU Pricing
3.1. Size and Design Airflow
Larger units deliver higher airflow and cost more. For example, a 4x4 ft FFU (1175×1175 mm) with 2000 m³/h airflow costs 15-20% more than a 2x4 ft unit.
3.2. Filter Type and Efficiency
- HEPA: cheaper, for ISO 6-8 cleanrooms
- ULPA: 20-40% more expensive due to denser filter media and stricter production
- ULPA required for ISO 4-5 areas
3.3. Material and Durability
- Powder-coated steel: cost-effective for dry food plants
- Stainless steel 304: corrosion-resistant, ideal for wet/chemical areas, 30-50% more expensive
3.4. Additional Features
- Adjustable fan speed: +10-15% cost
- Anti-static coating: +5-10% cost
- Noise reduction: +8-12% cost
3.5. Brand and Certifications
International brands (e.g., Nidec, Camfil) cost 25-40% more than local products but offer higher reliability. Certifications like ISO 9001, CE, RoHS, or GMP testing increase prices.
3.6. Order Quantity, Shipping & Installation
Bulk orders get 5-15% discounts. Stainless steel units have higher freight costs. On-site installation may add 5-10% to total cost.
