Negative Pressure Isolation Rooms & Tuberculosis (TB) Isolation Rooms

Negative Pressure Isolation Rooms maintain a flow of air into the room, thus keeping contaminants and pathogens from reaching surrounding areas. The most common application in the health industry today is for Tuberculosis (TB) Isolation Rooms. The infectivity of TB is extremely high and these rooms are essential to protect health workers and other patients.

The CDC recommends 12 air changes per hour (ACH) for TB Rooms. An ante room is always recommended, as this provides a barrier between the TB Room and hallways and limits the impact of opening doors and traffic. The exhaust air is normally filtered through a HEPA (High Efficiency Particulate Air) filter before being exhausted to the outside, where it is ultimately rendered harmless by natural elements. Air which is recirculated within the room is also normally filtered. Ultraviolet Germicidal Irradiation (UVGI), commonly known as UV light, may be used to augment HEPA filters, but cannot be used in place of HEPA filters, as their effectiveness on airstreams is limited.

Airmont's Ventilation / Filtration Units have been used throughout New York City's health care settings to comply with OSHA and CDC engineering control guidelines.

Automatic Room Pressure Control
Fan speed control maintains comfortable air flow levels during normal operation for improved compliance. Automatically increases air flow when doors are opened to maintain negative pressure and insure safety. The automatic control also maintains constant airflow throughout the life of the HEPA filter.

Local and Optional Remote Alarms
Constantly monitors filters, UV light, blower operation and entry or egress. Audible and visual alarms at the VFU signal trouble. An optional, remote alarm panel can be located at a station or terminals can be tied to a building automation system.

Durable, Tamper Resistant Construction
The VFU cabinet is painted steel, with a key lockable door.
