The nano-purification solutions NBA 3120 GF, 324 CFM Breathing Air Dryer is a modular system that first filters air using an M1 1.0 micron pre-filter and an M01 0.01 micron high-efficiency coalescing pre-filter. The NBA also reduces CO and CO2 levels using a 4-layer, mixed bed cartridge in aluminum extruded vessels. The first stage of the cartridge removes water vapor to -40°F/C pressure dew point and polishes CO2 using a novel activated alumina and 13X molecular sieve mix. The second stage utilizes activated carbon to remove hydrocarbons, odor, and taste. The last stage of the cartridge employs a catalyst to convert CO to CO2. All materials are snow storm filled for maximum packing density and are held in place by an integral 1 micron particulate after filter.
