Introduction to FFU Operation
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.
Step-by-Step Usage Instructions
1. Pre-Installation Preparation
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
2. Installation Process
Mount the FFU securely using the provided brackets
Connect to power supply following the wiring diagram (L/N/PE)
For multiple units, maintain 5-10mm spacing between adjacent FFUs
Install the HEPA filter (1170×570×69mm) with proper sealing gaskets
3. Initial Startup Procedure
Power on the unit and allow 5-minute stabilization
Verify uniform airflow across the entire face area
Check for abnormal vibrations or noises
Measure face velocity (should be 0.45±0.09 m/s)
Advanced Operation Features
Speed Control Technology
