FAF Products
FFU Fan Filter Unit Chemical Filter
I. Product Introduction
The FFU Fan Filter Unit with Chemical Filtration is an advanced cleanroom air recirculation system integrating particulate and molecular contamination control. This self-contained module combines:HEPA/ULPA filtration (ISO Class 3-5 compliance)，Activated carbon/VOC chemical filtration，EC motor technology for precise airflow control.
II. Product Advantages
1. Integrated Contamination Control
Removes both particles (≥0.3μm) and chemicals in one unit
Target-specific media options:
KMnO₄-impregnated carbon: Formaldehyde/ethylene removal
Acid-gas carbon: SO₂/HCl scrubbing for semiconductor fabs
2. Energy Smart Operation
EC motors reduce power consumption by 40% vs. AC FFUs
Variable speed control (0.3-0.5 m/s) with auto-adjustment based on sensor data
3. Plug-and-Play Deployment
Standard 575x575mm/1175x575mm ceiling grid compatibility
Tool-free filter replacement - Chemical cartridges swap in <3 mins
4. Regulatory Ready
Pre-validated for:EU GMP Annex 1 (Grade A/B zones)
SEMI F21 (AMC control in chip fabs)
ISO 14644-1 Class 3-5

V.FAQ
Q1: How often to replace chemical media?
A: 6-18 months depending on:VOC load (monitor via onboard sensors)，Carbon type (standard coconut: 12mo, KMnO₄: 6mo).
Q2: Can it handle corrosive gases like HF?
A: Yes - Specify:
316L stainless steel housing
Alumina-impregnated media for acid gases
Q3: Difference between wall-mounted vs ceiling FFU?
| Type | Airflow Pattern | Best For |
|---|---|---|
| Ceiling | Unidirectional downflow | ISO 5 cleanrooms |
| Wall | Horizontal laminar flow | Equipment shielding |
