DC-FFU Fan Filter Unit with HEPA Filter for Clean Room

Product Overview

The DC-FFU (Direct Current Fan Filter Unit) is a next-generation modular air purification system engineered for ultra-high-cleanliness environments. Designed specifically for energy efficiency and precision control, the 1175×575mm (2 * 4ft) model integrates brushless DC motors, HEPA filters, and intelligent control systems to deliver stable laminar airflow (0.45 m/s ±20%). Its compact, lightweight structure ensures seamless integration into ceiling keel systems while achieving ultra-low noise levels (<50 dB). Ideal for ISO Class 1-1000 cleanrooms, this unit excels in particle removal, airflow uniformity, and operational cost savings, making it indispensable for industries demanding stringent contamination control and sustainable energy practices

Key Features

✅ Brushless DC Motor Technology

Energy Savings: Consumes 30-50% less power than traditional AC-FFUs, with a typical power range of 50-220W, reducing long-term operational costs

Stepless Speed Adjustment: Enables precise airflow control (0–0.6 m/s) via PWM-driven motors, optimizing performance for dynamic cleanroom requirements

Extended Lifespan: Rated for 100,000+ hours (≈10 years) of maintenance-free operation, outperforming AC motors in durability

✅ Intelligent Control System

Multi-Channel Remote Management: Supports centralized control via software for real-time monitoring of speed, voltage, and fault diagnostics across large-scale installations

LED Digital Interface: Displays operational status, speed levels, and filter life, with customizable settings for automated adjustments

✅ High-Efficiency Filtration

HEPA Filters: 99.99% efficiency @0.3μm, paired with low-resistance PTFE or glass fiber media to minimize energy loss and extend filter life

G3 Pre-Filters: Captures larger particles, reducing HEPA load and maintenance frequency

✅ Structural Advantages
