PSS – Prefabricated Shaft System

The LaundryFab Prefabricated Shaft System (PSS) is a factory built exhaust duct system designed to be used for multi-story exhaust systems where a fire-rated shaft is required. The PSS is available in both single-wall and double-wall with optional integrated low-profile subduct risers, eliminating the need for fire/smoke dampers. Compared with field-fabricated shafts and subducts, this low-profile configuration can reduce the required area of the shaft by up to 52%, saving valuable space. The modular design assembles with a simple V-band for quick installation with no welding required. The PSS is ideal for clothes dryers, bathroom, and kitchen exhaust systems.

The PSS has a 3″ high temperature fiber-insulated double-wall, which provides a UL/ULC classified 2-hour fire-rated shaft eliminating the need for field fabricated duct work and a separate fire-rated shaft construction thus reducing material, labor, and installationcosts. The PSS is made in the USA and includes a limited lifetime warranty with engineering design support.

Single-Wall Configuration

The PSS also comes in single-wall configuration, great for installations in an existing shaft or fire-rated space.

Works great with the High Rise System (HRS) from LaundryFab!
