FFU： Air purification module for high-cleanliness environments

Core Components and Working Principle

Fan: Employs a direct-drive, high-efficiency centrifugal fan, featuring a long lifespan (over 50,000 hours), low noise (≤54dB(A)), maintenance-free operation, and low vibration.

Supports three-speed adjustment or stepless speed regulation, allowing for airflow adjustment to meet different cleanliness requirements.

Filters:

Pre-filter: Filters large dust particles, extending the lifespan of the HEPA filter.

HEPA/ULPA high-efficiency filter: Achieves a filtration efficiency of 99.99%~99.999% for 0.3μm particles, ensuring high cleanliness of the output air.

Filter replacement is convenient; the modular design reduces maintenance difficulty.

Casing: Typically made of galvanized steel, stainless steel, or aluminum alloy, featuring a lightweight yet robust structure that supports modular installation.

Internal Archimedes spiral air duct design reduces pressure loss and noise, improving fan efficiency.

Advantages and Features

Modular Design: Supports multiple units connected in series to form an ultra-clean production line, flexibly adapting to different spatial layout requirements.

Can be used independently or integrated into clean benches, clean corridors, and other equipment.

High Efficiency and Energy Saving: Maintains constant airflow even under the final resistance of HEPA filters, reducing energy consumption.

DC motors (EC) consume 30%~50% less power than AC motors (AC), resulting in lower operating costs.

Intelligent Control: Supports centralized computer control, capable of simultaneously managing the operation, speed adjustment, and status query of thousands of fans.

Equipped with fault indicator lights and external connection points for easy real-time monitoring and troubleshooting.

Easy Installation: Can be installed using suspended or floor-mounted brackets, adapting to different ceiling structures.

Lightweight design (typically weighing 15~45kg), facilitating handling and installation.
