FFU (Fan Filter Unit) fans are critical components in cleanrooms, laboratories, and industrial HVAC systems, ensuring precise airflow and contamination control. As a manufacturer with 20+ years of expertise in centrifugal fan design, WuJiang Deshengxin Purification Equipment Co., LTD addresses the most common questions about FFU fans, their applications, and how to choose the right one for your needs.
1. What is an FFU Fan?
An FFU fan refers to the centrifugal fan specifically designed for Fan Filter Units. Unlike standard fans, FFU fans are engineered to work seamlessly with HEPA/ULPA filters, providing consistent airflow (typically 0.3–0.45 m/s) while maintaining low noise levels (<55 dB). These fans are ideal for environments requiring ISO Class 1–5 air purity, such as semiconductor labs or pharmaceutical facilities.
Key Features:
High Static Pressure: Supports airflow through dense filters (e.g., H14 HEPA).
Energy Efficiency: Brushless DC motors reduce power consumption by up to 30%.
Compact Design: Fits standard FFU housings (575x575 mm or 1175x575 mm).
2. How to Choose the Right FFU fan?
a. Airflow Capacity
Match the fan’s airflow (measured in CFM or m³/h) to your FFU’s filter resistance. For example:
Standard Cleanrooms: 900–1,200 m³/h at 150–250 Pa static pressure.
High-Precision Labs: 1,500+ m³/h with 300+ Pa pressure.
b. Motor Type
c. Noise Levels
Prioritize fans with noise levels below 55 dB for labs or hospitals. Soundproofed models may cost 15–20% more.
d. Customization
Need non-standard sizes (e.g., 1,200x600 mm) or explosion-proof designs? Contact us for tailored FFU fan solutions.
3. What Affects FFU Fan Prices?
The following is the customization of a regular fan manufacturer：
Factor
| Price Impact | Example
|
Motor Type | +50–50–300 | EC motors add $200 vs. AC. |
Airflow Capacity | +100–100–500 | 1,500 m³/h models cost 450+��.450+vs.250 for 900 m³/h. |
Certifications | +20–30% | ISO 14644-compliant fans cost ~$550. |
Customization | +150–150–1,000+ | Explosion-proof upgrades start at $1,200. |
Average Price Ranges:
Standard FFU Fans: 80–80–300
Industrial-Grade Models: 350–350–1,500
As a full industry chain manufacturer with many years of research and production experience, Deshengxin's fan prices are very competitive, whether they are customized or not.
4. Maintenance Tips for FFU Fans
Regular Filter Checks: Clogged filters force fans to work harder, increasing energy costs by 15–25%.
Motor Lubrication: Extend lifespan by 2–3 years with quarterly maintenance.
Vibration Testing: Annual inspections prevent misalignment issues.
