The HFS Air Sampling System is the first system truly designed with the user in mind. Many of
its features have been incorporated after evaluation of current sampler technology and
extensive contact with its users. It is the intent of the HFS system to provide a versatile,
rugged, reliable, compact sampler employing modular design concepts and to allow the unit to
be upgraded to the needs of the user. The modular stack construction concept reduces repairs
and maintenance, resulting in minimum down time and maximum flexibility.
