2 Product Overview
Laminar Flow Hood Air Filter Fan Unit (FFU) is a modular terminal air supply device combining a fan and high-efficiency filtration. It is designed for industrial clean rooms, microelectronics, and pharmaceutical manufacturing. The unit inhales air from the top and filters it through a HEPA or ULPA filter, delivering clean air at a uniform speed of 0.45m/s±20%.
The DC Fan Filter Unit is optimized for stability and energy efficiency. Utilizing advanced brushless motor technology, these units can save approximately 12% more electricity compared to standard market products.

Frequently Asked Questions
Q1: Where are Fan Filter Units (FFU) commonly used?
FFUs are widely used in HVAC systems, painting stations, chemical plants, pharmaceutical facilities, clean rooms, power stations, and heavy metal industries to ensure air purity.
Q2: What are the international standards for air filters?
European standards include Pre (G1-G4), Medium (F5-F9), HEPA (H10-H14), and ULPA (U15-U17). American standards range from MERV5 to MERV20.
Q3: What makes DC FFU units better than AC versions?
DC units offer more stable voltage, higher durability, and significantly lower power consumption. Our units save approximately 12% more electricity compared to standard versions.
Q4: What are the primary testing criteria for your products?
Products are tested and manufactured according to EN779:2012 and ISO9001 standards to ensure high performance and air quality control.
Q5: Can the FFU system be integrated with other sensors?
Yes, the FFU control system can be connected with temperature and humidity sensors. The fan speed can automatically adjust based on pressure difference changes.
Q6: What is the standby power consumption of these units?
The units feature a low standby power loss of less than 1.2W, contributing to long-term energy savings in large clean room environments.
