By Ron Marshall A new maintenance manager was concerned about the compressor control in his plant.Β To him, it appeared that the performance of his three screw compressors was substandard, especially this variable speed drive compressor.Β And, he was running out of compressor capacity, the plant pressure was dropping to unacceptable levels, which was affecting […]
Air Compressors
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.Β 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 […]
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.Β A VSD compressor should be taking the partial load, with the fixed speed units either running […]
DTM70-H is worldβs first direct-transmission mounted PTO driven air compressor
VMAC has announced the product release of the DTM70-H, the worldβs first direct transmission mounted PTO driven air compressor with hydraulics. The VMAC DTM70-H maximizes productivity with up to 70 cfm of air at 100 psi, and up to 14.9 gpm of hydraulic flow at 3265 psi, all at 100% duty cycle. βThis new innovative […]
Compressed air efficiency: 7 tips to get the best bang for your buck
By Ron Marshall The words βbang for your buckβ are frightening when it comes to compressed air, but there are definitely very good opportunities to save money by optimizing the way you operate.Β Compressed air is one of the most costly utilities used in industrial and commercial sites.Β Only about 10% of the energy input […]
Smart compressor/vacuum pump from Thomas gives users design options
Gardner Denver Thomas has released its latest new product developmentβthe 2320Z series compressor/vacuum pump. This new platform is ideal for the O2 concentrator market, but because of its higher maximum rated pressure and vacuum capability, is also an excellent choice for other medical or laboratory applications. It incorporates advanced design and patent-pending technologies as well […]
Dearing Compressor announces acquisition of Pittsburgh-based Kruman Equipment
Dearing Compressor & Pump Co., the second oldest Gardner Denver industrial air compressor distributor, recently completed its first ever acquisition, merging with the oldest Gardner Denver distributor, Pittsburgh-based Kruman Equipment. The acquisition allows Dearing to effectively double their industrial air compressor business while providing counterbalance to the dynamic energy market. CEO and President, Rick Dearing, […]
How do I put my compressor to sleep?
By Ron Marshall One of the biggest wastes of energy in a compressed air system is allowing your air compressor to use energy when it is not producing air. This can be a big problem with screw compressors, due to the way these compressors typically operate. Well-maintained modern day screw compressors running in load/unload control […]
How important is pressure to my compressed air efficiency?
By Ron Marshall The pressure at which you operate your system has a significant effect on the energy efficiency of your air compressors, and Β can affect the air consumption of the compressed air powered tools and equipment in the plant. Running at higher pressure than desired causes higher system flow and more power consumption, increasing […]
