External Air Inlet Filter Assembly (Part Number STD558)
Beginning in May 2014, we started supplying an external air
inlet filter assembly to improve the CIRAS-3 resistance to dirty,
dusty environments. As described above, the internal gas
circuit and optics are protected with several filters but this
external filter also provides added protection and can easily be
changed. It easily connects to the CIRAS-3 “AIR IN” port as
shown below:
This assembly is supplied with a filter element, 48 um, blue
(Part Number STD556) as standard. For severe dusty
environments, we recommend the filter element, 10 um, Yellow
(Part Number STD555).
