To prepare an accurate quotation, it is helpful to provide air flow rate, working pressure, required dew point, inlet air temperature, voltage, frequency, and application details. If you need a nitrogen generator, you should also provide the required nitrogen purity and flow demand.
If your project has special requirements such as low purge loss, water-cooled design, intelligent control, large-flow capacity, or a complete compressed air treatment package, those details should also be included. The more complete your technical information is, the easier it is to recommend a suitable product and provide a more accurate quote.
