• Required fire rating and cleanroom classification
• Style of fire-rated pass-thru chamber (floor-mounted and wall-mounted options available)

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.
