FILTER REPLACEMENT
The nitrogen generators contain three (3) separate cartridge filters and a water separator. It is
recommended that each filter be replaced at a minimum as part of an annual preventative maintenance
program. ECS offers a replacement filter kit for each model. When maintained properly the nitrogen
separation membrane will have an expected service life of twenty (20) years.
ECS Recommends that all cartridge filters (Filters 1, 3 & 4) in the nitrogen generator be replaced when
replacing the filters.
