A compressed air auditor found, during a site visit to a mine, that compressed air condensate was left to drain from stopcock at the bottom of piping low spots. The oily condensate pooled on the ground, creating a slippery mess that polluted the environment and caused a safety hazard. This mine had no air dryers […]

Emerson announces 2021 ASCO Engineering Scholarship winners
Emerson has announced the recipients of its 2021 ASCO Engineering Scholarship Program, continuing its long-standing commitment to rewarding and supporting students dedicated to innovating the future through a career in engineering. The recipients are Jessica Ruby of Holland Township, New Jersey, a senior mechanical engineering student at The College of New Jersey, and Kolin Limburg […]
Festo advances digital automation and AI in production
The growing pace of technological change, political disputes over trade relations and increasingly dismal prospects for the global economy are putting the manufacturing industry under pressure, according to officials at Festo, Esslingen am Neckar, Germany. The Corona pandemic is a particular challenge, and it clearly shows the importance of digital transformation and Industrie 4.0, they […]
New high-pressure proportional controls
The new Cordis HP500 from Cincinnati-based Clippard uses the company’s proven EV line of electronic valves to allow for steady, repeatable downstream pressure under static conditions. The result is precise, linear pressure control within a closed-loop system with high accuracy and repeatability. The Cordis HP500 uses a microcontroller, integrated pressure sensor, and two Clippard EV […]
Schmalz launches virtual trade show
In person trade shows and conferences are nonstarters at the moment. Thus, Schmalz Inc., Raleigh, N.C. is pursuing a different path to present its new products to a wide range of design engineers and trade professionals. SchmalzEXPO, a virtual vacuum-technology trade show, is underway without any need for masks and social distancing requirements. The J. […]
Compressed air fail: Condensate disposal
Air compressors and refrigerated air dryers typically produce large amounts of condensate, especially when operating in hot humid conditions. A fully loaded 150-hp compressor at a local manufacturer was producing about 750 cfm of compressed air on a 24 x 7 basis. The ambient temperature was 70° and relative humidity 50%. At this output the compressor […]
Schmalz compact ejector generates vacuum in tight spaces
Small, powerful and scalable SCPM vacuum generators from J. Schmalz GmbH, Glatten, Germany, represent a new series of compact ejectors that can be integrated directly into a vacuum gripping system thanks to a slim, lightweight design. The new SCPM family was developed in response to the growing demand for space-saving, decentralized vacuum generators that combine […]
Pressure gauge withstands high overpresssure
The Ashcroft T6500 stainless steel, solid front pressure gauge is now available with the XRA overpressure option. This feature adds an overpressure mechanism that restricts the motion of the Bourdontube after the specified full scale value is reached.As a result, the gauge can withstand up to 400% overpressure without damage, often eliminating the need for […]
What is Class 0 air?
The international standard ISO 8573-1 (2010), “Compressed air — Contaminants and purity classes,” provides a classification system for the main contaminants in compressed air systems. The standard specifies a number of purity classes for compressed air with respect to particulates, water and oil, independent of the location in the compressed air system at which the […]
Compressors meet shipboard air demands
Many engineers are familiar with plant compressed-air networks that pipe high-pressure air to pneumatic tools, industrial robots and countless types of production and packaging equipment. Perhaps not as widely known, but equally as important, compressed air also handles critical tasks on large commercial ships. Compressed air is used onboard in a number of ways. One […]
