Clean Compressed Air Brochure - Norgren - #5

Breathing Air:eg:face masks and hoods, air agitation.The typical application assumes thatair intakes are of a reasonable quality with no C0 or C0 Heavy Duty Lubrication:eg:large slow moving cylinders.In such applications large amounts oflubricant are required for effective lubrication.Again a soft start/dump valve is shown but isdependent upon the application. (Figure 6). Direct Injection Lubrication:eg:conveyor chains.The application does not allow for‘fog’type lubrication because of the surrounding environment and absence of a lubrication chamber. (Figure 8).
2 contamination. It may in someinstances be a consideration to remove watervapour. (Figure 4) Figure 4. Figure 6. Figure 8. Shut-off valve, general purpose filter, Ultraire filter, regulator.

Oil-Free Applications:eg:paint spraying, foodstuffs, film processing, powders.These applications need to be freefrom any water deposits in the downstreamsystem. For many installations this will requireair drying. The drying medium (for desiccant or deliquescent dryers) will need protecting fromoil to allow it to work efficiently and thedownstream system will also need protection from accidental migration of the material into it.A typical arrangement would be as figure 5 andin some instances it might be worth consid- ering an oil vapour removal filter too. Critical Pressure Control (Instrumentation):eg:precision regulation, fluidic systems, air gauging, process control.A typical arrangement is shown, whereoil aerosols which can prevent fast response ofdownstream devices, need to be removed.Dependant upon air quality drying may not be required. (Figure7) Continuous Processes:eg:paper mills, chemical plants.Another facet of Norgren’s Olympian Plus is theability to make duplex systems. This is invalu-able for systems which cannot be shut-down,such as continuous process plant. Two identical air sets are joined together and one may be isolated (and serviced) whilst the other set is in operation. (Figure 9). Figure 5. Figure 7.
