Nitrogen/Air Generator Whisper-0-10 Hybrid, N2 10Nl/min, Air 35Nl/min

Nitrogen and Dry Air Generators Whisper-0 Hybrid

The Whisper-0 Hybrid Nitrogen and Dry Air Generators has been developed to meet specific requirements in terms of nitrogen flow, purity and pressure on some LCMS interfaces that also require filtered and dried air. The simple high efficiency membrane technology allows the separation of nitrogen from the other components of the compressed air inlet. The customer has also a source of dried filtered air in case of analysis that requires it. The low pressure drop, just one bar, allows the unit to be connected to an existing dry and oil-free compressed air source in the lab.

On the inlet there are two coalescent filters for separation of water and oil aerosols from compressed air, removing particles down to 0.01 micron. Next stage is active carbon filter removing moiety and another contaminants from air. During next membrane separation stage, compressed air is forced through a hollow fiber membrane, with selective permeation of the different components – nitrogen, oxygen, carbon dioxide, water vapor and traces of rare gases – depending on the rate of diffusion. The rate of diffusion of nitrogen through the membrane is slower than the other components, which thus flow outside of the fiber membrane. Just nitrogen remains inside which is then subsequently discharged, ready for use. A part of incoming air, after coalescing and particulate filtering procedure, is dried through a fiber membrane column and distributed into two separate outlets.

Cost savings

Gas bottles are insufficient to ensure good lab productivity. With Whisper-0 Hybrid, no pipeline is required to carry the gas from the storeroom to the lab. The Nitrogen/Air Generator investment can normally be paid back in less than a year.

Improved Safety

Nitrogen and Dry Air produced at low pressure and at room temperature eliminates the risks relating to high pressure gas bottle use and the handling of liquid nitrogen.

Simple Installation

The Whisper-0 Hybrid Nitrogen/Air Generators are very easy to install in the lab. No power connection is required| No background noise due to the absence of moving parts| Bench-top or wall-mounted installation is possible in order to save bench space.
