Air supply systems for operating rooms and prep rooms

Downflow plenum

UDAF air supply system
A UDAF air supply system (i.e., a plenum) is an air supply system that is integrated into the ceiling of the operating room. The system is used in operating rooms and prep rooms that require a sterile work area (ultra clean area).

Clean HEPA filtered air is blown from the plenum directly above the ultra clean area. As a floor marking, the projection of the plenum is shown as an ultra clean area (Protected Area, according to VCCN RL7). This is the sterile work area in which the instruments, the OR table and the surgical team should be set up.

Medexs designs, manufactures and installs, depending on the application standard or custom-made air supply systems. Our team considers functionality, size of the blow-out field and the expected Protected Area, which is determined in consultation with the client and users.

Crossflow plenum

Horizontal (cross)flow plenum

A Horizontal plenum (or crossflow for short) is a horizontal air intake system (recessed or surface mounted wall system) for use in a prep room. Clean HEPA filtered air is blown out of the system. The instrument sets should be unpacked in the airflow of the crossflow system.

The ultra clean area (Protected Area, according to VCCN RL7) is shown with a marking on the floor in a prep room for the crossflow unit. Instrument tables on which sterile instruments are placed should be positioned within this floor marking.
