2X4 2X2 FFU Fan Filter Unit Air Purification Equipment For Cleanroom

Custom FFU Fan Filter Unit For Electronics Manufacturing Pharmaceuticals Biotechnology

Features

FFU stands for Fan Filter Unit, which is a type of air filtration system used in cleanroom environments to filter and circulate air.

The purpose of an FFU is to provide a continuous supply of clean air to a cleanroom or other controlled environment.

The unit typically consists of a fan, a filter, and a housing.

Application

FFUs are commonly used in cleanrooms, which are used in industries such as electronics manufacturing, pharmaceuticals, and biotechnology, where it is critical to maintain a controlled environment free from contaminants.

They are also used in laboratories and other facilities where the control of airborne particles is important.

Besides, we are mainly engaged in Designing, Manufacturing, Testing & Verification, Manufacturing Processes and Quality Control, Engineering & Installation, and After-Sale Service of clean rooms and are devoted to controlling and treatment of air PM2.5, formaldehyde, benzene, VOC, and other toxic and hazardous substances.

Technical Data

Main Components of an FFU

1. Housing/Frame:

   • Material: Typically made of stainless steel, aluminum, or galvanized steel to provide durability and resist corrosion.
   • Design: Lightweight and compact to allow easy installation in cleanroom ceilings or workstations.

2. Fan Unit:

   • Type: Usually consists of a centrifugal or axial fan.
   • Purpose: Draws in ambient air and pushes it through the filter at a controlled velocity.
   • Features: Often equipped with speed controls to adjust airflow according to cleanroom requirements.

3. Air Filters:

   • Pre-Filter: Captures larger particles to extend the life of the main filter.
   • HEPA or ULPA Filter: Removes fine particles, including microbes and contaminants, ensuring a clean airflow.
     • HEPA Filter Efficiency: Captures particles ≥ 0.3 microns with 99.97% efficiency.
     • ULPA Filter Efficiency: Captures particles ≥ 0.12 microns with 99.999% efficiency.

4. Motor:

   • Type: Often a high-efficiency, low-noise motor.
   • Drive Mechanism: Direct-drive or belt-driven.
   • Features: Designed to operate continuously with minimal energy consumption and reduced vibrations.

5. Air Distribution System:

   • Design: Incorporates baffles or diffusers to ensure uniform air distribution across the filter.
   • Purpose: Maintains laminar airflow to minimize turbulence.

6. Control System:

   • Includes controls for fan speed, monitoring airflow, and filter status.
   • Advanced units may feature IoT connectivity for remote monitoring and control.

7. Vibration Dampeners:

   • Installed to minimize vibrations from the fan and motor, ensuring consistent airflow and quiet operation.

8. Sealing Mechanism:

   • Gaskets or gel seals around the filter to prevent air leaks and ensure all air passes through the filter.

Typical FFU Design Process

1. Air Intake: Air is drawn in from the surrounding environment through the pre-filter.
2. Filtration: The pre-filter removes larger particles, while the HEPA or ULPA filter captures fine particles, microbes, and contaminants.
3. Air Delivery: The filtered air is pushed out uniformly, maintaining laminar flow for a clean environment.

Applications

• Cleanrooms (pharmaceuticals, semiconductors, biotechnology).
• Medical facilities.
• Laboratories.
• Food processing plants.
