A medium-sized tire shop was having troubles with pressure during their busy times. In the spring and fall, during agricultural planting season, the pressure went way down when servicing the many farm implement tires coming in. And the shop’sΒ compressor would cut out when they needed it the most β a very frustrating experience. A compressor […]

So you bought a VSD compressor β Now what?
Congratulations, variable speed drive compressors can save you lots in avoided electricity costs β the invention of this type of compressor has helped to save millions of dollars across the world. These compressors consume only the electricity required of them, they track the compressed air flow up and down and adjust the speed of the […]
SMART becomes standard in vacuum generator
The piCOMPACT23 SMART is an IO-Link-ready vacuum generator platform available from Piab. Offering operation with either standard 24V IO or IO-Link, the new SMART compact all-in-one ejector is ready to meet the future. Previously offered as an optional added feature, IO-Link is now included as a standard option. A generic input/output (IO) communication technology, IO-Link […]
Compressors are dust magnets
Compressor rooms are usually dirty, dusty places that take care and attention to keep clean. Itβs not that the compressor operators are slobs, itβs that the air compressors must suck in surrounding air to work and to keep cool. This creates a negative pressure around the compressors that draws in anything airborne. The photograph shows […]
How do you improve air powered ventilation?
A compressed air assessment was done at an aircraft maintenance facility. Part of the study was identification of inappropriate compressed air uses. The study identified some compressed air powered ring jets used for ventilation of aircraft fuel tanks while the internals were being inspected. The study concluded that these ring jets were using about one-third […]
Compressed air fail: The danger of assumptions
Part of a good compressed air assessment is the measurement of the plant pressure gradient. This can be accomplished by placing data loggers at various points in the plant along the distribution piping. If this is done, a time-based plot of the data can show where the biggest pressure loss occurs. Often times, loggers might […]
Signal operated air pressure relay offers precise control
ControlAir LLC has announced the introduction of the new Type 7150 Precision Air Relay. The Type 7150 is a high precision, multi-stage pressure relay offering fine adjustment and maximum stability under variable operating conditions. High resolution output control combined with very high relief capacity make the Type 7150 the choice for pneumatic counter balance applications […]
Compressed air fail: Filter change
Plant management at the paper products plant were always on their guys to save money. Therefore, when it came time to do the maintenance on their desiccant air dryer, the replacement of their dryer filters was delayed. This was not thought to be a problem because the differential gauge on the filter was showing in […]
Customer turns it off β and saves!
By Ron Marshall A leakage assessment was done at a small industrial shop and a constant flow was found in a CNC machine. This machine was very rarely used, perhaps running less than 1% of the time β however, it was consuming a significant flow for internal purging. While testing this flow, a duty cycle […]
