Selection issues for low-negative-pressure fans

I would like to ask all netizens: The flow rate of the fan is 4000 m³/h, with an inlet pressure of -15 kPa (minus 15 kilopascals). It’s an exhaust fan. 1. Are there fans with such low pressure? Can the selected centrifugal fan meet the requirements? 2. If the outlet pressure of the fan is 0, can the total pressure be considered as +15 kPa? Can the fan be selected based on a flow rate of 4000 cubic meters at +15 kPa?
