1. Simple Laminar Flow Cabinet (FFU + Curtain Type)
Description: This is an economical and versatile laminar flow solution, ideal for areas requiring a localised ISO Class 5 environment for processes that are not critical or hazardous. It is constructed using a Fan Filter Unit (FFU) mounted atop a metal frame, with the sides enclosed by transparent PVC strip curtains or soft plastic curtains. This design allows for easy access and high visibility while maintaining a downward unidirectional airflow. It is a cost-effective choice for general bench work, equipment protection, minor assembly tasks, or as a temporary clean zone in laboratories and electronics workshops. Its simple design also allows for easy relocation.
| Parameter | Specification |
|---|---|
| Standard Dimensions (W×D×H) | 1200×800×2000 mm (Common) / Highly Customizable |
| Construction Material | FFU Housing: Powder-coated steel / Enclosure: Transparent PVC strip curtains |
| Filtration System | Pre-filter + HEPA Filter (H13, 99.97% @ 0.3µm) integrated within the FFU |
| Airflow Velocity | Adjustable, typically 0.3 - 0.6 m/s (via FFU speed control) |
| Lighting | LED light kit integrated into the FFU (Optional) |
| DOP Test Port | Not Available |
| Front Access | Full open front with PVC strips |
| Typical Application | Creating local clean zones, basic assembly, product protection |
2. Standard Laminar Flow Cabinet (Stainless Steel with DOP Port)
Description: This is a high-performance, rigid-walled cabinet designed for critical applications in stringent environments like pharmaceuticals, biotechnology, and medical device manufacturing. Constructed entirely from 304 or 316 stainless steel with a smooth, coved interior for easy cleaning and disinfection, it offers superior durability and contamination control. The key feature is the integrated DOP (Dispersed Oil Particulate) test port, which allows for in-situ integrity testing of the HEPA filter to comply with ISO 14644 standards. This closed design provides a more stable and secure ISO Class 5 environment than curtain types, protecting both the product and the operator.
