You can find the default ONI stats simply by looking at the buildings descriptions in the build menu or in the database.

enabled - "true" or "false" - Will enable the building in the tech tree and build menus
energyConsumption - Amount of watt the machine will consume
pumpRate - Amount in kg the pump will take at a time
maxPressure - Max pressure in kg the vent will stop working at
thermalConductivity - The thermal conductivity multiplier. Example: 0.5 will make it half as conductive. Insulation tiles for example has a multiplier of 0.04

I took a look at the wiki I'm assuming the .2 for the gas pump means 200.0 g/s then? Since the normal gas pump has 500.0 g/s. That's the part that was confusing me.

Yes, all the values are in kg.

Okay thanks

Also I had an idea for a building in same theme as your mod wall/floor tile deodorizers. It would basically be an airflow tile that cleans the air. Seemed like an idea right up your alley.

setting for 250kg?
