The DDL Series of double-diaphragm oilless linear pumps include 230V models suitable for use where higher voltages are required. Other versions include lower-voltage ac models and a 12V dc unit. UL listings are certified for 15 models in the line. The models in this series of compressors and vacuum pumps offer a spectrum of air flow and pressure/vacuum capabilities. Free air flow can be as low as 0.39 cfm or as high as 8.6 cfm with pressure to 10.5 psi and vacuum to 12.1 inches Hg.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
