How to Choose a Cleanroom Fire-Rated Pass-Thru Chamber and Door System

Before choosing a fire-rated cleanroom pass-through system, you will need to consider:
  • Size and type of items that need to move through the pass-through
  • Required fire rating and cleanroom classification
  • Style of fire-rated pass-thru chamber (floor-mounted and wall-mounted options available)
  • Construction material (stainless steel is most common)
  • Need for a fully welded body (for easier cleaning and sterilization)
  • Need for a specialized bio-style design (for the strictest isolation and sterilization standards)


Types of UL Fire-Rated Pass-Through from Clean Air Products

Wall-Mounted Fire-Rated Pass-Thru Windows

Our fire-rated pass-thru wall-mounted windows use a two-door airlock system that provides a convenient way to transfer products from a standard air-quality area into a cleanroom without exposing the cleanroom to outside particles. All wall-mounted fire-rated pass-through windows meet USP 800 cleaning requirements, are easy to wipe down, and feature a completely flush (lipless) design.

Floor-Mounted Fire-Rated Pass-Thru Doors

Clean Room Product's fire-rated pass-thru door systems are constructed from stainless steel and are ideal for applications involving the transfer of larger pieces of equipment and components or wheeled carts. A floor-mounted fire-rated pass-through cabinet or door allows for minimal personnel to enter the cleanroom, ensuring limited particle exposure within the cleanroom.

FAQs for Cleanroom Fire-Rated Pass-Thru Units

What UL fire ratings apply to cleanroom pass-thrus?

Cleanroom fire-rated pass-thrus are typically classified under UL 10B and UL 10C standards, with individual ratings indicating how long the pass-thru can withstand fire exposure. Common ratings include 20-, 45-, 60-, and 90-minute classifications.

When do cleanrooms require fire-rated pass-thrus?

Fire-rated pass-thrus are required when a cleanroom wall is used within a fire-rated wall or barrier, or when local building codes or safety regulations specify fire protection requirements. They are often used in industrial and manufacturing facilities that contain fire hazards or utilize flammable materials.

How do fire-rated pass-thrus differ from standard pass-thrus?

UL fire-rated pass-thrus offer the same level of contamination control as standard pass-thrus, with the added benefit of certified fire resistance. Unlike standard pass-thru chambers, fire-rated pass-thrus are built with UL-listed fire-resistant components that prevent the spread of flames and smoke for defined periods.
