ULTIMA compressors from CompAir are 100% oil and silicone-free and meet the ISO 8573-1 Class Zero standard (2010), making them the ideal choice for stringent oil-free applications e. g. within food and beverage, pharmaceutical, and electronic industries.
A major drawback that traditional two-stage oil-free compressors have is their reliance on a gearbox; not only does this consume large amounts of energy but requires high volumes of oil to lubricate the gears. ULTIMA has two per-manent magnetic motors that replace this gearbox design. The variable-speed motors can achieve speeds of up to 22,000rpm and efficiencies greater than IE4, also allowing the airends to be driven at different speeds dependant on demand.
Also, while conventional models still use oil to lubricate and cool a system’s motors and airends, ULTIMA uses water in a closed-loop circuit to cool these components. This allows greater heat transfer and cooling efficiencies, as well as en-suring as little oil as possible is used in the system for assured air purity.
Installing an ULTIMA air-cooled compressor is calculated to result in an annual reduction of 52 tons of indirect CO2 emissions compared to a conventional oil free variable speed compressor. That’s equivalent to 5,207 trees!
