The new SATA filter 500 series, 100% technically clean air. Clean air is where it all begins. In paint application, this applies particularly to compressed air quality. Even the tiniest quantities of oil or dirt and increased levels of moisture can cause coating flaws leading to time-consuming, costly rework. The SATA filter series 500 is available either as a one-stage sintered filter with water and oil separator, as a two-stage combination filter with sintered and fine filter, or as a three-stage filter unit with additional sintered activated charcoal filter. Every six months, all filter stages are maintained together in a procedure that takes just a few minutes without the need for tools, thanks to the bayonet lock and defined position of the filter cartridges, which are replaced simply by inserting them. Furthermore, a flow-optimised cyclone separator minimises pressure drop in the filter system and ensures a constant air flow of approx. 3.800 Nl/min (with four connections).
