18 AIR SYSTEMS // THE BASICS Building an Efficient Air System A Good Filtration System How it works Water and dirt cause more problems in compressed air lines than anything else. A typical 7.5 HP compressor brings in an average of 3 gallons of water from the atmosphere per day along with dust and dirt. It is important to eliminate water and dirt from your air system. A good filtration system will extend the life of your tools and eliminate downtime and unnecessary service calls on your equipment. WORK STATION FOR AIR OPERATED TOOLS WORK STATION FOR PAINT SPRAYING WORK STATION FOR AIR INFLATION WORK STATION FOR ULTRA CLEAN AIR FOR CRITICAL APPLICATIONS 5 IMPORTANT STEPS TO A WORK STATION DROP 1 Main line filter and regulator should be placed at least 20 feet from the compressor. The air will cool down, allowing much of the water vapor to condense naturally for removal by filtration. 2 Main line piping should slope down from point of origin by 1/8" per foot. Any water in the line will flow down to the lowest point for draining. 3 All line drops (work stations) should be taken from the top of the main line. This prevents water which forms in the main line from flowing into branch lines. 4 Galvanized pipe is recommended when building an air system. 5 Follow illustration(s) when building a work station drop. 6 Use manufacturer recommended lubrication oil or AW32. Place a drain trap at low points to remove water. Also utilize on main line at low points. Slope main line 1/8" per foot away from compressor. Use galvanized pipe. Drop a 6" pipe to drip leg. Goose-neck all work stations. Place a “T” wherever filters go. BUYER'S GUIDE ASCOT SUPPLY CORPORATION WARNING: For more information go to www.P65Warnings.ca.gov.
