High-Efficiency Reverse Suction Fan Filter Unit with Flange Port – Advanced Cleanroom Air Filtration Solution

In today’s highly regulated industries such as pharmaceuticals, biotechnology, semiconductors, and precision manufacturing, achieving and maintaining cleanroom standards is critical. The Reverse Suction Fan Filter Unit with Flange Port (FFU) is a cutting-edge air purification solution engineered to provide stable laminar airflow, minimize particle contamination, and optimize energy efficiency.

Unlike conventional fan filter units, this model adopts a reverse suction design combined with a flange port connection, enabling secure integration with duct systems and modular cleanroom ceilings. It is designed to meet the strict requirements of GMP-certified facilities, ISO cleanrooms, and high-precision laboratories, offering a reliable and flexible clean air solution for multiple industries.

The reverse suction system ensures smooth airflow distribution, reducing turbulence and achieving more stable laminar flow. This not only enhances filtration efficiency but also minimizes energy consumption during continuous operation.

• Equipped with HEPA or ULPA filters depending on application needs.

• HEPA filters (H13/H14) remove ≥99.97% of particles ≥0.3 μm.

• ULPA filters (U15–U17) provide ultra-clean performance, removing ≥99.9995% of particles ≥0.12 μm.

This ensures compliance with international standards such as ISO 14644 and GMP cleanroom requirements.

The integrated flange port structure allows quick, reliable, and leak-proof connections with ductwork and cleanroom modules. This makes it especially suitable for modular cleanroom construction and retrofitting existing facilities.

The FFU is powered by a brushless EC fan motor, offering:

• Up to 30% energy savings compared with conventional units.

• Low noise levels to create a comfortable working environment.

• Long operational lifespan with minimal maintenance needs.

Manufactured with high-quality galvanized steel or aluminum alloy, the housing is resistant to corrosion, chemicals, and deformation. Despite its robust build, the unit remains lightweight, simplifying handling and ceiling installation.

The modular design ensures that filter replacements and fan maintenance can be carried out quickly without interrupting production for long periods.
