BFU Bottom-Access FFU | Large-Capacity HEPA Filtration System for ISO Cleanrooms | Tool-Free Filter Replacement & Energy Efficient

The BFU Bottom-Access FFU 1220X620X350 is a high-performance, large-capacity fan filter unit designed for ISO Class 3-6 cleanrooms in industries like pharmaceutical manufacturing, biotechnology, and precision electronics. Featuring an innovative bottom-access design, this FFU allows for quick and tool-free HEPA filter replacement, significantly reducing maintenance downtime and labor costs.

Key Features

1. Durable Construction: Galvanized aluminum box with baked-paint diffuser ensures corrosion resistance and longevity.

2. Efficient Fan System: MRJH motor paired with a metal impeller delivers stable airflow and ultra-low noise.

3. Precision Airflow Control: Three-speed adjustable wind speed (0.45–0.75 m/s ±3%) for flexible cleanroom requirements.

4. H13 Filtration: Non-partition HEPA filter achieves 99.99% efficiency at 0.3μm particles.

5. Bottom-Detachable Design: Simplifies maintenance and filter replacement.

6. Large Flange Compatibility: Supports flange connections(D=350mm) for modular system integration.

7. Low Noise: Engineered for 46–55 dB (±5 dB) operation at 1.5m below the filter.

Application Scenarios

Cleanroom air purification in pharmaceutical, electronics, and biotechnology facilities.
Manufacturing zones requiring ISO-certified H13 filtration with precise airflow control.
Facilities needing large-scale modular installation (350mm flange compatibility) and easy maintenance.

FAQ :
1,Q: What makes the BFU Bottom-Access FFU ideal for ISO Class 3-6 cleanrooms?
A: This FFU combines large-capacity HEPA filtration (H13/H14, 99.95–99.995% @ 0.3µm) with a 1220x620mm airflow footprint, ensuring uniform ISO compliance in pharmaceutical and semiconductor facilities. Its bottom-access design allows maintenance without disrupting laminar airflow—critical for high-cleanliness zones.
2,Q: How does the tool-free filter replacement work, and what are the time savings?
A: The patented bottom-access panel eliminates ceiling dismantling. Replace filters in under 5 minutes (vs. 30+ minutes for traditional FFUs), reducing labor costs by 60%. A slide-lock mechanism ensures airtight resealing post-maintenance.
3,Q: Can this energy-efficient FFU integrate with existing cleanroom HVAC systems?
A: Yes, the EC motor’s Modbus RTU/PROFINET compatibility allows seamless BMS integration. Real-time airflow adjustments cut energy use by 30% while maintaining ISO airflow velocity standards (0.45 m/s ±10%).
