The FID Gas Purifier treats both air and hydrogen. It includes two combination hydrocarbon/moisture removing cartridges on a wall mount manifold. It can be bench mounted using included legs. Each cartridge has inlet and outlet fittings so that the air and hydrogen supply are purified simultaneously. Replacement cartridges are available; depleted cartridges can also be returned to CRS for regeneration. Each cartridge has a capacity of 1.4g water to an outlet of 1ppm, and 12g hydrocarbons as n-butane. Maximum pressure 200psi.
