Eh, its just something id happen to know working in cafeterias and other places in my journey. Im not sure exactly what your usage rate would be , but oil-free air compressors can be worth the price for  occasional applications.. They lower the risk of oil contamination and  long-term maintenance costs. Basically  less oil filters to buy, you aint using it that much. However, traditional oil-lubricated compressors may be a better choice for heavy-duty, continuous use due to their typically longer lifespan and lower INITIAL cost, but the upkeep is heck.  Depends on ya budget , go with your intuition honestly would be best! Any other question, you could have a small chat, im sure to clear it up.
