33.1 HEPA in-line filter for premixed gas
The round-shape in-line 0.2µ HEPA filter for premixed gas removes any particles found
in the incoming gas. Failure to use the HEPA filter may cause damage to the high precision
flow sensor, which calculates the amount of gas entering the system and disturbing the
gas flow system.
Please follow these safety precautions when changing the filter:
•
Always use the original filter (contact Esco Medical or your local distributor for
more details or ordering).
•
Change the filter once every year.
•
Failure to change the filter on time will result in low/no cleaning of incoming pre-
mixed gas.
•
Warranty void if wrong/ non-original filter is used.
Please refer to the service manual for replacement instructions.
