The Zero Air Generators AMS 8100 / AMS 8150 are operating on the principle of the catalytic oxydation. At an inlet pressure of up to 15 bar (abs) the AMS 8100 / AMS 8150 generate up to 600 Nl / h of carbonmonoxide- and hydrocarbon free Zero Air. The systems operate highly efficient even at this flow rate; the Zero Air Generators AMS 8100 / AMS 8150 can eliminate 99.95 % of 1000 PPMv CH4 in air.
