KLC Modular Cleanroom ISO 5 to ISO 9: Complete Equipment List, Setup Cost, and Build Timeline
KLC Modular Cleanroom ISO 5 to ISO 9: Complete Equipment List, Setup Cost, and Build Timeline
June 09, 2026
A modular cleanroom (or portable cleanroom) offers a flexible, cost-effective alternative to traditional "built-in" facilities. Whether you need an ISO 5 micro-environment or an ISO 8 assembly hall, the modular approach allows for rapid deployment and future expansion.
At KLC International, we provide "Turnkey Modular Kits" that include everything from the structure to the validation papers. Here is the breakdown of what you need and what it costs.

The KLC One-Stop Advantage
1. Modular Structure: Aluminum or SUS 304 frames that bolt together in hours.
2. Integrated Controls: One touch-screen to control FFUs, lighting, and pressure.
3. Fast Validation: Pre-engineered to pass ISO 14644-1 audits on day one.
4. Global Shipping: Modular components are packed in standard crates for easy export.
FAQ: Frequently Asked Questions
1. What is a modular cleanroom? It is a freestanding cleanroom built from pre-fabricated components like aluminum frames, fan filter units (FFUs), and panel walls.
2. How long does it take to build a modular cleanroom? Depending on size and ISO class, a small room (20m²) can be manufactured and shipped in 4 weeks and installed on-site in 3-5 days.
3. Is a modular cleanroom as "clean" as a traditional one? Yes. If engineered correctly with high FFU coverage and HEPA filters, a modular room can easily achieve ISO 5 or even ISO 4 standards.
4. Can I move my modular cleanroom? Yes. That is the primary advantage. You can disassemble, move, and reassemble it in a new location or expand its size.
5. What flooring is best for a modular cleanroom? Anti-static PVC or Epoxy-coated concrete are the most common. For ISO 5, a raised perforated floor is recommended for vertical laminar flow.
6. Do I need an air shower for a modular room? For ISO 6 and cleaner, an air shower is highly recommended to protect the internal environment from personnel-borne dust.
7. How do I maintain a modular cleanroom? Regularly monitor pressure gauges, perform monthly surface cleaning, and replace HEPA filters every 2-3 years.
8. What is the difference between hardwall and softwall? Hardwall (Acrylic/PC) is more durable and maintains pressure better. Softwall (PVC curtains) is cheaper and allows for easy equipment movement.
