Stainless steel FFU (Fan Filter Unit) is a clean air supply equipment that integrates a fan, box and high-efficiency filter. The equipment is installed on the ceiling of a clean room, clean shed or other clean space, and the fan drives the air through the filter and then sends it into the clean area.
Stainless steel FFU mainly uses SUS304, SUS201, SUS430, SUS316 and other stainless steel materials, and can be configured according to the specific use environment and project requirements.
Stainless steel materials have good corrosion resistance, surface cleaning and maintenance convenience, and material stability, so they are suitable for clean environments that have specific requirements for equipment materials and cleaning and maintenance.
In actual use, appropriate stainless steel materials should be selected based on environmental conditions, cleaning methods, corrosive media, and project standards.
SUS304 and SUS316 are two common stainless steel materials. SUS304 can be used in more conventional clean environments; for projects with specific corrosion conditions or higher requirements for materials, SUS316 can be considered based on actual working conditions.
The specific selection of the two materials should be confirmed based on the site environment, cleaning methods, media conditions and project technical requirements.
Can. Stainless steel FFU can be equipped with HEPA filters according to cleanliness level and particle control requirements.
Common solutions include H13, H14 and other filtration levels. The specific filtration level needs to be selected based on the clean room grade, target cleanliness, air volume and filter resistance.
ULPA filtering scheme can be configured according to project requirements.
If the application environment has higher requirements for the control of ultrafine particles, a suitable ULPA filter can be selected based on the cleanliness level, filtration efficiency, air volume and system resistance.
After using a ULPA filter, the filter resistance usually needs to be included in the fan selection, so you cannot just replace the filter and ignore the fan parameters.
Common specifications include 575×575 mm, 615×615 mm, 915×615 mm, 1175×575 mm and 1175×1175 mm, etc.
The actual size needs to be determined based on the clean room ceiling module, installation space, filter specifications and air supply requirements. For special installation spaces, non-standard size designs can also be made based on project conditions.
The air volume and speed are related to the FFU size, fan, motor, filter resistance and working static pressure.
Some conventional FFU configurations can refer to the air supply speed of approximately 0.45 m/s. The specific air volume needs to be determined based on product size and fan performance. For example, different specifications such as 575×575 mm, 1175×575 mm and 1175×1175 mm will have different reference air volumes.
The final air volume and speed should be based on the specific product model and technical parameters.
Noise is related to fan type, operating speed, filter resistance, installation method and test conditions.
The reference noise of some conventional configurations can be controlled within about 59 dB. Actual projects should confirm noise data based on specific product configurations and agreed test conditions.
Whether wind speed adjustment is supported depends on the fan, motor and control system configuration.
According to the project requirements, the corresponding speed regulation or control scheme can be selected to adjust the FFU operating status. The specific adjustment range and control method need to be confirmed based on the actual model.
Can. Stainless steel FFU is often used in modular clean room ceiling systems, and can also be used in clean sheds and other clean spaces that require modular air supply.
Before installation, it is necessary to confirm the ceiling module size, FFU overall size, filter specifications, maintenance space, and on-site load-bearing and installation structure.
Stainless steel FFU can be used in a variety of clean environments according to different cleanliness levels and material requirements, such as:
Semiconductor and electronic manufacturing, pharmaceuticals, food, laboratories, optoelectronics, precision manufacturing and other clean production environments.
Specific product configurations need to be selected based on industry processes, cleanliness levels and on-site environment.
Can.
Aili Industrial can size, box material, filter specification, filtration grade, fan, motor, power supply and control method according to project requirements.configure the FFU
For non-standard ceiling sizes, special installation spaces or specific air supply requirements, engineering design can also be carried out based on project conditions.
It is recommended to confirm the following information when selecting:
Cleanliness level → Room size → Number of FFU → Target air speed → Air volume → Static pressure → Filter level → FFU size → Stainless steel material → Power supply → Control method
If the clean room area and target wind speed have been determined, these parameters can also be provided to the engineering staff, who will further match the FFU specifications and quantity.
There is no uniform fixed price for stainless steel FFU. The specific cost will be affected by factors such as box size, SUS304 or SUS316 material, fan, motor, filter grade, control method, and purchase quantity.
If a quotation is required, it is recommended to provide FFU size, filtration level, air volume or speed, material requirements and purchase quantity for calculation based on specific configuration.
