SS Fan Filter Unit AC
Our AC Fan Filter Unit (FFU) is designed to provide stable, uniform, and reliable airflow
for cleanrooms and controlled environments. The unit is manufactured using high-quality
Stainless Steel SS-304 with 1.2 mm thickness, ensuring excellent corrosion resistance,
hygienic surface finish, and long-term durability. The powder-coated surface enhances
protection and makes the unit suitable for pharmaceutical, medical, and electronic cleanroom
applications.
The FFU is equipped with a single-phase capacitor-run AC motor (as per the motor label
shown in the image), designed for continuous-duty operation. The motor operates at a rated
speed of approximately 1050 RPM and is paired with an adjustable speed control system
offering Low, Medium, and High RPM settings, allowing precise airflow control based on
cleanroom requirements.
With its compact 230 mm low-height design, this FFU is ideal for modular cleanroom
ceilings where space optimization is critical.
