Types of Cleanroom Construction


When you are planning to build a cleanroom for your business, process or production, the first primary consideration should be: which type of construction suits your needs? Thanks to years of evolution, the cleanroom industry has expanded to its mammoth size and the choices are very contradictory.

Thus, to help your planning process of building a cleanroom facility, here are four of the most popular types of cleanrooms that are in demand and offered by ACH Engineering. This article aims to establish a comparative study of these four types based on costs, industry, usage, purpose, and other considerations.

Traditional Cleanroom Construction

  • Easy and quick modification
  • Performance-based on fabrication material (Drywall/ Masonry)
  • Expensive due to onsite construction

A traditional cleanroom is a controlled contaminant room where the air is filtered and recirculated back to keep airborne microbes, aerosol particles, chemical vapors, and dust at a pre-fixed level. Completely field-fabricated, traditional cleanrooms have drywall installation, acoustical ceiling and epoxy paint. Additionally, it is important to abide by protection and precaution protocols from the initial stage of installation, as wallboards are easily prone to fungal damage.

Cladding (PVC, FRP and Other Material)

  • Wide variety of wall panels
  • Mechanical and aesthetic benefits
  • Easy to repair
  • Smooth finish to avoid any risk for micro growth

There is a wide variety of cleanroom wall panels available in the market. It is important to choose the wall panel cladding wisely based on the purpose of your cleanroom, as they render long-term mechanical as well aesthetic benefits. ACH Engineering offers wall panel cladding made of polyvinyl chloride (PVC), or reinforced plastic (FRP).

Softwall Cleanroom

  • Lightweight construction with transparent polymer walls
  • Customizable and reconfigurable
  • Compatible with ULPA or HEPA filters

For those looking at a temporary cleanroom set up for a short-term project, ACH Engineering recommends softwall cleanroom. Softwall cleanrooms are cheaper, portable and versatile. They are also available in standard preconfigured size or can be customized based on your requirements. In addition, they are not designed for positive internal pressure and do not require external bracing. The softwall cleanroom frame is usually made of aluminum alloy and delivered with a white-powder standard finish.

Modular Cleanroom

  • Regulatory compliance
  • Easy to install and maintain
  • Eco-friendly green construction
  • Rapid and clean installation

Designed to provide a sterile GMP environment, modular cleanrooms are prefabricated setups particularly used by businesses, processes and productions that are highly sensitive to environmental decay. Ultra-low particulate air (ULPA) filters and/or high-efficiency particulate air (HEPA) filters are installed to continuously recirculate air and keep it ultra-clean. ACH Engineering offers choices of modular design, modular materials and equipment to clients based on the industry and purpose of the modular cleanroom.
