These oil-free air compressor models contain absolutely no oil anywhere in the compressor and have been certified ISO 8573-1 Class Zero (2010) and silicone free.
Water injected, silicone free and oilfree air
Industries such as Electronics, Chemical, Pharmaceutical, Food and Beverage depend upon pure oil-free compressed air as a safe, clean energysource to drive production lines. Sometimes the air comes intodirect contact with the product being created, so it is criticalthat the purity of this air is maintained at all times. You cansee how this is achieved by the DH series in this video - click the design tab, to watch this. The DH Series comprises of the following features:
Single-stage, direct-driven compression element maximises efficiency and minimises maintenance
High quality water injection lubricates, cools and seals the compression process, maximising efficiency
No gearbox means no need for associated oil lubrication
Low bearing loads and low speeds mean sealed-for-life bearings can be used, requiring no oil lubrication
Regulated speed technology available to reduce energy costs
Comprehensive control ensures safe and reliable operation and includes remote
communication capability
Fully packaged and silenced enclosure reduces noise and simplifies installation
Design
The unique design achieves lower speeds combined with lower operating temperatures - both resulting in high efficiency and reduced component wear. Using a single-stage, direct-driven motor without gears or belts, maximises efficiency. Limiting the compressed air to the application demand with regulated speed ensures that no energy is wasted.
