Clean Booth with FFU High-Efficiency Filter‌

A clean booth with an integrated FFU is a modular localized air purification system that provides clean air by incorporating a Fan Filter Unit (FFU). It is suitable for areas with high cleanliness requirements, such as production lines in industries like electronics, pharmaceuticals, and food processing.

‌Core Structure and Working Principle‌

The clean booth typically consists of a frame, anti-static curtains (or glass panels), an FFU, and purification lights. Its core working principle is as follows: The FFU fan creates negative pressure, drawing in external air. The air first passes through a pre-filter (primary filter) and then through a high-efficiency filter (HEPA or ULPA) for fine filtration. The filtered air is then delivered vertically into the booth at a uniform speed of 0.45 m/s ±20%, forming a unidirectional airflow to achieve the required cleanliness level (e.g., Class 100–100,000).

‌Key Features and Advantages‌

• ‌Flexibility & Mobility‌: Modular design for easy assembly; some models come with casters for flexible relocation based on production needs.
• ‌Energy Efficiency‌: Low air resistance, energy-efficient motors, and variable speed control result in lower energy consumption compared to traditional central air systems.
• ‌Scalability‌: FFU units can be easily added or adjusted in quantity to adapt to process changes.
• ‌Cost-Effectiveness‌: Lower investment and faster installation than building a full cleanroom, with no special requirements for ceiling height.

‌Installation and Maintenance Considerations‌

• ‌Pre-Installation Cleaning‌: Ensure the cleanroom and HVAC system are thoroughly dust-free before installation.
• ‌FFU Installation‌: Handle high-efficiency filters with care; inspect for damage to filter media and seals before installation. Conduct a leak test.
• ‌System Commissioning‌: Run continuously for at least 12 hours after installation, followed by cleanliness testing.

‌Typical Applications‌

Clean booths are ideal for localized high-cleanliness zones, such as:

• Chip production lines in electronics manufacturing.
• Assembly areas for pharmaceutical products.
• Operations involving high-precision instruments.
