Introduction
The new M Air T® Compressed Gas and Air Sampling Kit is designed
especially to monitor the microbiological quality of compressed gas
and air used in the pharmaceutical and food & beverage industries.
Connected to the M Air T Isolator Pump ATBPUMP01, the new
sampling kit allows accurate sampling and microbiological monitoring
of a compressed gas sample, by direct impaction onto the M Air T prefilled agar cassette.
The pre-sterilized M Air T agar cassettes used with the M Air T
Compressed Gas and Air Sampling Kit are easier to handle, especially
when wearing gloves, significantly reducing the risk of inadvertent
contamination. The M Air T Compressed Gas and Air Sampling Kit is
manufactured from stainless steel, with sanitary Tri-Clover
connections, making it autoclavable.
The design of the M Air T Compressed Gas and Air Sampling Kit
allows one to sample compressed gas or air up to 5 bar (73 psi) of
pressure, without any pressure reducer.
Applications
The M Air T Compressed Gas and Air Sampling Kit, connected to the
M Air T Isolator Pump, is suited for a variety of applications, as follows.

Precautions/Limitations
■ Autoclave all parts at 121 °C for 20 minutes before any compressed gas or
air sampling.
■ Use only with the M Air T Isolator Pump.
■ Use only M Air T cassettes with this unit.
■ Do not use for microbiological monitoring of compressed O
■ Do not sample gas or air at pressures above the specified limit of
5 bar (73 psi).
