OABC D screw booster compressors are designed for the demanding conditions of industries that require medium pressure at continuous production. They work 24/7 seamlessly, and have high overall equipment efficiency. Provide a suitable option to replace piston boosters; at end of five years, they generate savings of up to 15-20% of total cost of ownership. […]

Dry vacuum pump from Leybold maximizes efficiency in industrial settings
Short, reliable and clean production processes are more important than ever for the increasingly digital and globally active value chains, in addition to high-quality results. Vacuum technology provides a significant contribution to meeting these requirements. This is why Leybold has designed the new VARODRY vacuum pump series for efficient industrial vacuum processes. This oil-free, air-cooled vacuum pump as […]
How clean is my compressed air?
Many compressed air systems are designed with certain expectations about the quality of the compressed air introduced into the plant. Often, some sort of compressed air quality level is used to help guide the design the system, like those set out in Air Quality Standard ISO 8573-1. This specification guides the user as to what contaminant […]
Should I turn my compressor off at night?
Often, because compressors are located in a far off corner of the building, air compressors are left to run all night and on weekends. If there are no production activities during these hours, the air compressor(s) will continue to feed leaks and other miscellaneous loads, such as air consuming equipment left on, or air dryer […]
Compressed Air Fail: Poor VSD performance
By Ron Marshall A new maintenance manager was concerned about the compressor control in his plant. To him, it appeared that the performance of his three screw compressors was substandard, especially this variable speed drive compressor. And, he was running out of compressor capacity, the plant pressure was dropping to unacceptable levels, which was affecting […]
Why does my compressor make water?
You may have noticed water coming out of your compressor. Some people ask where does it come from and why is it there? An additional important question to ask is: how well is it being removed? Atmospheric air contains water in vapor form, the amount depending on the temperature and relative humidity of the inlet […]
What size of pipe should I used to connect my air compressor?
Quite often, the compressed air pipe connected to an air compressor is sized to the same diameter as the connection on the compressor outlet. But this can be a mistake because it may lead to excessive pressure loss that can affect the operational efficiency of the compressor. For example, one manufacturer, to save costs, puts […]
Is it worth buying dew point control for an air dryer?
Dew point controls on desiccant dryers should definitely be considered. If not controlled, the purge air circuit on a desiccant dryer will consume constant flow even through it might not be required. This represents a significant area of waste in your compressed air system, but something can be improved with a retrofit. Purge air is […]
What are common locations of pressure loss in compressed air systems?
A small fiberglass manufacturer had a problem. Their tools were not performing adequately; they would stall when production workers tried to really work them, reducing production throughput. A compressed air auditor was called in to investigate, he found that the air compressors were running at 140 psi, as high as they could go, but the […]
How do I set up a VSD compressor to run with a fixed speed?
If you have a variable speed drive (also called variable frequency drive) compressor installed in your system and want it to work correctly with your fixed speed compressors, then things need to work a little bit differently that normal. A VSD compressor should be taking the partial load, with the fixed speed units either running […]
