Filters remove dirt, water, and other contaminants that, left unchecked, can hasten the demise of air-powered equipment. Many of the latest versions have high dirt-holding capacity for longer life, improved flow paths that lead to better energy efficiency, and can even alert users when they need maintenance. Here’s a look at some of the newest products on the market.
Energy-efficient pneumatic circuit design often involves mounting valves as close as possible to the actuator. Reducing the length of tubing between a valve and actuator — and with it the volume of compressed air required for each actuator cycle — can cut compressed air consumption by as much as 20%.
In today’s fast-paced world, consumer buying decisions are often made on the spot in just a few seconds. An eye-catching package among overflowing retail shelves and multiple options can make all the difference in steering a shopper’s choice.
Thus, marketers spend countless hours on striking designs, but converting them to practical packaging — that protects the product inside while being visually appealing — is the job of engineers like the ones at H.C. Moog GmbH, a machine-engineering company based in Rüdesheim am Rhein, Germany.
The growing trend towards mobile healthcare and equipment for home use means medical devices must get smaller, lighter, and more durable. That has med-tech engineers looking to piezoelectric valves for pneumatic applications. Piezo valves offer advantages over solenoid valves such as smaller size, higher efficiency, and quieter operation, and they are well-suited for controlling flow and regulating vacuum and pressure.
Machine builders face a vexing problem when there’s a need to rotate large or unwieldy products in assembly, handling, and packaging applications. Engineers often must select and size an electric motor; evaluate direct, belt, or gear drives; find bearings that can handle the loads and give long life; and assemble the entire package and fit it into often-limited space.
A better option may be a guided pneumatic swivel module that provides a versatile, rotating drive for large and hard-to-handle loads.
Molded composite parts are commonplace in products ranging from boat hulls and hot tubs to storage tanks and wind turbines. However, regulatory pressures are impacting the composites manufacturing process, and that has producers turning to pneumatic controls.
Metal extrusion may seem like an old-style industrial operation, but Presezzi Extrusion SpA, headquartered near Milan, Italy, has elevated it to a high-tech enterprise. The company designs, builds, and commissions presses for extruding aluminum, steel, copper, and brass.
