latest company case about Guangzhou Cleanroom Construction Co., Ltd. Certifications

Fan Filter Units (FFUs) are essential components in creating controlled clean environments across various industries. Our factory's FFU model represents cutting-edge air filtration technology, combining high-efficiency particulate air (HEPA) filtration with precision airflow control. This guide will walk you through proper installation, operation, and maintenance procedures to maximize your FFU's performance.

• Site Assessment: Verify ceiling structure can support the unit's weight (approximately 25kg)
• Power Requirements: Ensure availability of AC220V, 50Hz power supply
• Space Verification: Confirm minimum 50cm clearance above the unit for proper air intake

1. Mount the FFU securely using the provided brackets
2. Connect to power supply following the wiring diagram (L/N/PE)
3. For multiple units, maintain 5-10mm spacing between adjacent FFUs
4. Install the HEPA filter (1170×570×69mm) with proper sealing gaskets

1. Power on the unit and allow 5-minute stabilization
2. Verify uniform airflow across the entire face area
3. Check for abnormal vibrations or noises
4. Measure face velocity (should be 0.45±0.09 m/s)

Our FFU's direct-drive centrifugal fan offers:

• Stepless speed adjustment from 30-100% capacity
• Automatic compensation for filter loading (maintains 1000 m³/h airflow)
• 62 dB maximum noise level at full speed

• Single unit operation for localized clean zones
• Linear arrangement for Class 100 assembly lines
