Zero Air Gas Generator (without Air Compressor) - Model: ZA-10L is intended to accept compressed air from either an internal or external compressor. The oil-free compressor sends air via a high-efficiency coalescing input filter, which traps moisture that may harm the system. This lowers background noise and improves the sensitivity of your analyses. Zero Air Gas Generator (without Air Compressor) - Model: ZA-10L is used to prevent any form of particle from entering the analytical equipment, and an output particle filter is utilized. This is used to provide clean, dry, hydrocarbon-free air.
