What is an Airborne Infection Isolation Room?

Also known as negative pressure isolation rooms, airborne infection isolation rooms (AIIR) are used by patients for hospitals and medical centers to prevent cross-contaminations and airborne infections from spreading throughout the facility.

These rooms are commonly recommended by the Center for Disease Control and Prevention (CDC) to help protect the public from diseases and infections that spread easily like tuberculosis, measles, and the coronavirus (COVID-19).

  • Central or point-of-use HEPA filters capable of removing particles 0.3 μm in diameter for supply (incoming) air
  • Well-sealed rooms
    • - Proper construction of windows, doors, and intake and exhaust ports
    • - Smooth, cleanable ceiling tiles
    • - Walls sealed above and below the ceiling
  • Ventilation to maintain ≥12 ACH
  • Directed air flow: design that filters air into one side of room, across patient’s bed and then exits on opposite side of room
  • Self-closing door on all room exits
  • Back-up ventilation equipment

Integrated Isolation Room Components

isolation room wall


PortaFab’s systems utilize aluminum-faced, class A wall panels that are easy-to-clean, non-combustible and provide excellent sound control.

isolation room door


PortaFab’s heavy duty wall systems can accommodate a wide variety of heavy-duty, hospital-grade doors including anti-microbial, stainless steel doors, impact doors and sliding doors for sealing off entire areas.

isolation room window


Multiple window units can be seamlessly integrated into isolation walls including our flush and beveled windows that allow for easy cleaning by eliminating hard-to-clean edges that collect, particles and more.

isolation room wall coving


Radius coving is used to create fully flush corner transitions and seamless wall-to-ceiling and wall-to-floor connections. By eliminating corners, the radius coving system allows for total "cleanability." Wall-to-wall and wall-to-ceiling junctions can be trimmed with an extruded coving that features a large 3" radius.

HEPA Filter Units

Rooms can be outfitted with ceiling-mounted fan filter units that are integrated into existing mechanical systems, wall mounted systems or even portable systems like Envirco's Hospi-Gard™ IsoClean™ system shown here.

gasketed ceiling grid system

Gasketed Ceiling Grid System

PortaFab wall systems integrate seamlessly with our gasketed, heavy-duty ceiling grid that can support fan filter units, diffusers and light fixtures. The ceiling system creates an air-tight barrier between the space and ceiling plenum to prevent transmission of contaminants into the room.
