Vacuum pump selection

The gases being removed are as follows: H2O at 437 kg/h, AIR at 17.25 kg/h, NH3 at 23 kg/h, and CO2 at 4.6 kg/h. The temperature is 60°C, and the average molecular weight is 18.30. For energy-saving reasons, we plan to switch to a mechanical vacuum pump. We would appreciate advice from experts on how to choose the right model. We consulted some manufacturers, who suggested a vacuum pump with an evacuation rate of up to 500 M3/h, but we don’t think this is reliable. We welcome guidance from professionals or manufacturers.

1. What level of vacuum is required； 2. At this vacuum level, what volume of gas is required to determine the pumping volume?
My post mentions the components and the required vacuum level
Air extraction rate: 2920 Am3/h
