Air Purifier (Standalone)

Factorio mod: the Krastorio 2 air purifier as a standalone building for vanilla Factorio, with a configurable absorption radius. No Krastorio 2 or Space Age required.

Mod portal: https://mods.factorio.com/mod/air-purifier-standalone

Features

• Air purifier (2x2, 75 kW): removes pollution from all chunks within a configurable radius while it has power and a filter.
• Configurable radius (startup setting, in tiles, default 64): every chunk whose center lies inside the circle is cleaned, the purifier's own chunk always. Pollution is taken proportionally, so the dirtiest chunks get cleaned fastest.
• Configurable absorption (map setting, default 50 pollution/min per purifier, like K2).
• Radius visualization when placing or selecting a purifier.
• Radius on the map/minimap, toggleable per player via a shortcut bar button or SHIFT + ALT + P.

Recipes (vanilla ingredients)

• Air purifier: 10 steel plate, 4 advanced circuits, 20 plastic bars, 1 engine unit
• Pollution filter (chemical plant): 2 steel plate, 2 plastic bars, 5 coal
• Restore used filter (chemical plant): used filter, 2 coal, 50 water
• A filter lasts 480 s; there is a 10% chance it is destroyed.
• Unlocked by Air purification (red, green and blue science).

Compatibility

• Not compatible with Krastorio 2 (it already contains the air purifier).
• Prototype names are kept identical to Krastorio 2 (kr-air-purifier, kr-pollution-filter, ...), so mods made for the K2 purifier may work.
