Products Description

• Housing/Casing: Constructed from stainless steel, aluminum, or coated galvanized steel for durability, cleanability, and corrosion resistance.HEPA/ULPA Filter: The core filtration element, mounted on the discharge side, providing final air cleaning.

• Centrifugal Blower Fan: Typically a backward-curved impeller design, providing stable airflow with good energy efficiency and low noise. Units may feature single or multiple fans (for redundancy).

• Pre-filter: Usually a primary (G4) or medium-efficiency (F8) filter located at the fan inlet. It protects the main HEPA filter and extends its service life by capturing larger particles.

• Control System:

  • Speed Control: Modern FFUs predominantly use Electronically Commutated (EC) motors, allowing infinite variable speed control via 0-10V DC, PWM signals, or network commands. This enables precise airflow adjustment and significant energy savings compared to older AC motor designs.

  • Monitoring: May include integrated differential pressure sensors (to monitor filter loading), status indicator lights, alarm functions, and communication interfaces for connection to Building Management Systems (BMS).

• Airflow Diffuser/Perforated Plate: Mounted below the filter, it helps to equalize and stabilize the discharged airflow, promoting uniform laminar flow.
