The 520 Series of air compressors and vacuum pumps are for the recovery of ozone-depleting and other refrigerants. Because the 520 is oilless, it can recover many types of refrigerants. In addition, a high single-stage compression ratio of 50:1 provides recovery rates of 5-15 lbs/min for liquids and 0.5-1 lb/min for vapor. Other features include all wetted aluminum parts, and lightweight die-cast aluminum components.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
