RINCIPLE OF
O
PERATION
The
Sanitaire
®
Room Air Sanitizer is categorized as a germicidal ultraviolet fixture that utilizes germicidal ultravi-
olet lamps that are completely enclosed within a stainless steel exposure chamber and is safe for use in a clean, dry
environment. The
Sanitaire
®
effectively destroys airborne microbes including: bacteria, mold and virus in enclosed
spaces.
The
Sanitaire
®
design has been carefully conceived to provide germicidal ultraviolet exposure for air disinfection.
The dosage, as it applies to ultraviolet disinfection, is a function of time, and the intensity, of ultraviolet radiation, to
which the air is exposed. The exposure time, in seconds, is the total time it takes the air to move through the ultraviolet
field, produced by the germicidal lamps. Exposure time is related to the airflow rate; the higher the airflow, the lower
the exposure time or the lower the airflow, the higher the exposure time.
All components are mounted in a stainless steel frame. Access to the lamp/exposure chamber is gained through the
interlocked, access door. Fixture operation can be monitored from the base panel.
The operation of the
Sanitaire
®
Room Air Sanitizer Model RSCS280 is as follows:
1.
Air is drawn into the fixture through the the louvered filter panel.
2.
LED indicator lights provide positive indication of operation of germicidal ultraviolet lamps.
3.
The air is forced into the exposure chamber, where it is irradiated by the germicidal ultraviolet lamps.
4.
The purified air exits the fixture, through the louvered exhaust panel, located at the opposite end of the fixture.

IMITATIONS
•
Overexposure to germicidal ultraviolet rays will result in the irritation of the eyes and reddening of the skin. For
that reason, it is of the utmost importance that your ultraviolet application be carefully planned and implemented
so as to avoid exposure, of personnel, to direct or reflected ultraviolet rays.
•
The American Conference of Governmental Industrial Hygienists (
ACGIH
) has established that the ultraviolet
radiant exposure incident for unprotected eyes or skin should not exceed 0.2 microwatts per square centimeter
(
µ
W/cm2
) at 254 nanometers (
nm
) for an eight (8) hour period. (
