Based on Energy Audits conducted by the U.S. Department of Energy, over 95 percent of compressed air systems have areas perfect for energy saving opportunities.? More than 30 percent of air costs in a plant can be associated to inappropriate uses or artificial demand, costing a typical end-user plant a minimum of 1cfm =1/4HP =.207Kw@$.06/kwh = $110/yr?.

 

　　In air audits conducted by Parker Hannifin, the use of uncontrolled blow offs as one of the top air consumption issues on factory floors was identified.? In this application, compressed air is directed through an air nozzle to provide a steady stream of air blow at a part to either dry it, clean it from debris, blow it off a conveyor, etc.? It is not uncommon for these applications to continuously discharge air, even when a part was not present.?

 

　　The Parker Air Saver has been released in Asia and Europe and has numerous documented success stories.? The Air Saver generates a rapid pulse of air, not a continuous flow.? This pulsation has two major benefits:

 

　　1.Reduces Compressed air costs by as much as 40% - 50% as opposed to typical applications of constant flow.

 

　　2.Improves efficiency due to the pulsed air blow off.? Compared to continuous air blow, the pulsed air blow hits the work repeatedly, improving the efficiency of the air blow for drying and removing debris.

 

　　Other benefits are:

 

　　·Reduces Green House Gases (CO2 emission associated with production of compressed air).

 

　　·Easy installation into existing pneumatic systems with no additional PLC programming required (see photos below).

 

　　·Quick ROI (Return-On-Investment).

 

　　·Aligns well with corporate Sustainability programs & objectives.

 

　　The Air Saver is available in sizes ranging from M5 ports, 5 CFM flow to 1 ?” ports, 530 CFM.? Other features include adjustable pulse frequency & duty cycle, silicon free grease version for paint shop applications, adjustment needle - on time/off time.
