DESCRIPTION
IMPORTANT
You must read this manual in its entirety to ensure proper
operation of your unit.
The AirCon-2 Air Sampling System is a powerful envi-
ronmental air sampler used to collect air samples in-
doors and outdoors. It is equipped with useful perfor-
mance features industrial hygienists need most; easy
set-up, compact size, battery pack operation, program-
mable timing functions and DC portability.
Table 1.1 (below) lists the available AirCon-2 models.
The AirCon-2 high volume air sampling system consists
of a positive displacement pump with a unique pat-
ented regulator system which maintains flow constant
over a flow range of 2-30 LPM. The sampler maintains
air flow constant for sampling of airborne particulate,
hazardous dust and low concentration pollutants using
many popular filter cassettes. The volume of air that
passes through the filter cassette is determined by the
following:
Air flow x Elapsed time = Volume
The unit is set up in the required location and
plugged into a properly grounded voltage source.
DC version units are connected to either a 2-hour or
4-hour battery pack and/or to a power module which
is designed to power DC version units from a stan-
dard AC source.
The AirCon-2 system provides a telescopic sampling
mast which is extended and to which the air hose/
support tip is connected. The media, typically a filter
cassette, is inserted into the end of the sampling
hose. The other end of the air hose is connected to
the “Air Inlet” located at the front of the sampler.
After positioning the unit and setting up the sampling
mast stand, the unit can be turned on. Air flow is set
by use of the external flow adjust knob and is indi-
cated on the built-in rotameter.
Programmable models offer a touch keypad and LCD
display which allow the user to program sampling
routines. Programmable timing functions include:
start and stop times, intermittent run, delay, run/hold
and memory storage of up to three custom timing
programs. The full-function display and touch pad
offer key-in programming and visual monitoring of
all timing functions during programming and sampler
operation.
