Main Features
- High-efficiency filtration:Filter element made from ultra-fine glass fiber paper and coated paper.
- 999% filtration efficiency at 0.3 μm, according to the provided specification.
- Class 100 cleanlinessfor controlled clean-air applications.
- Low resistance:The filter design is intended to maintain efficient airflow while controlling filtration resistance.
- High dust-holding capacity:Suitable for continuous air purification applications under normal temperature, pressure and humidity conditions.
- Multiple sizes:Three models provide different airflow capacities and installation dimensions for different cleanroom layouts.
- Compact design: Suitable for integration into local purification equipment and cleanroom systems.
Working Principle
The FFU combines air circulation and high-efficiency filtration in one unit.
Air Intake
Air from the surrounding environment or cleanroom circulation system enters the FFU through its intake side.
Fan-Driven Airflow
The integrated fan generates the airflow required to continuously move air through the filtration system. The three models provide airflow capacities of 800 m³/h, 1080 m³/h and 2200 m³/h, respectively.
High-Efficiency Filtration
The air passes through the high-efficiency filter element made from ultra-fine glass fiber paper and coated paper. The filter is specified at 99.999% efficiency for 0.3 μm particles.
Clean Air Delivery
After filtration, the purified air is delivered into the controlled area, supporting a cleaner local environment and helping reduce airborne particle contamination.
Continuous Air Purification
The FFU can operate continuously as part of a cleanroom or localized purification system, maintaining controlled air circulation during sensitive mushroom-production processes.
Suitable Raw Materials and Mushroom Applications
It can be used in facilities producing or cultivating various edible mushrooms, including:
Capacity / Production Scale & Automation Level
The three FFU models provide different airflow capacities:
FFUXH800A – 800 m³/h
A compact model suitable for smaller local purification requirements, laboratory areas and smaller clean zones.
FFUXH1080A – 1080 m³/h
Provides a higher airflow capacity and a larger overall housing than the 800 m³/h model, suitable for larger local purification applications.
FFUXH2200A – 2200 m³/h
The largest model in this range, providing higher airflow for larger cleanroom sections or areas requiring greater air circulation.
The FFU itself is an air purification and circulation device rather than an automated mushroom production machine. Its operating function is primarily continuous air movement and filtration. Multiple FFUs can be incorporated into a larger cleanroom system according to the required room configuration and airflow design.
The appropriate number of FFUs should be determined according to the room dimensions, required air-change rate, cleanroom layout and overall HVAC design, rather than simply selecting units based on mushroom production tonnage.
Integration with Mushroom Production Equipment
Upstream Equipment
The FFU can support clean areas following:
- Mushroom Substrate Mixer
- Mushroom Bagging Machine
- Mushroom Sterilizer
- Steam Generator
- Sterilization Rack
- Substrate Cooling Area
- Air Shower Room
Downstream Equipment
The FFU can also support areas containing:
- Mushroom Inoculation Machine
- Laminar Flow Clean Bench
- Incubation Room
- Incubation Racks
- Mushroom Fruiting Room
- Container Mushroom Growing Room
- Mushroom processing areas
Substrate Preparation → Bagging → Sterilization → Cooling → Cleanroom / FFU → Inoculation

FAQ
No. An FFU is an air purification and circulation device. It does not sterilize mushroom substrate. Substrate sterilization should be carried out using dedicated equipment such as a mushroom sterilizer or steam sterilization system.
All three models are specified with a high-efficiency filter rated at 99.999% efficiency at 0.3 μm, with Class 100 cleanliness specified for the units.
Selection depends primarily on the required airflow, room dimensions, installation space and cleanroom design. The available models provide 800 m³/h, 1080 m³/h and 2200 m³/h airflow capacities. For a complete cleanroom project, the required quantity and model should be determined based on the overall airflow design.
Yes. A typical clean-area arrangement can combine an Air Shower Room → Cleanroom/FFU → Laminar Flow Clean Bench → Inoculation Area. The exact layout should be designed according to the facility’s production process, room structure and cleanliness requirements.
