Flow switch

Brass, stainless steel

Model 2000 flow switch is engineered to monitor liquid flow or no flow conditions in such applications as steam cleaners, lube oil systems, and coolant systems. Featuring an orifice design, it allows for low-pressure drops to pass large particulates. A hermetically sealed SPST reed switch is actuated when the piston, holding a magnet, displaces the liquid flow or no flow condition. Flow switch operates in pressures up to 1,500 psig and flow rates from 0.5 to 3 gpm. Thomas Products, www.thomasprod.com Enter 589

Oil cooler and filter

High temperature applications

Static eliminator

Fits in tight spaces

The 3-inch super ion air knife produces a sheet of airflow that floods a surface with static-eliminating ions. The air knife also cleans surfaces of particles, dust, and dirt, improving surface cleanliness, production speed, and product quality. Adjust the 3-inch ion column from a blast to a breeze using less than one SCFM compressed air at 5 psig. Applications include web cleaning, pre-finishing dust removal, neutralizing plastics, and printing and packaging operations. Exair Corp. www.exair.com Enter 595

Bar feeder

Feeds stock at high speeds

The Mini-Rhinobar(R) hydrodynamic bar feed system is designed for high-speed feeding of small stock and quick feed tube changeover. Feed tube sizes range from 1/8 to 15/8 inch, and feed stock ranges from 1/16 to 15/8-inch diameter, in 6- or 12-ft bar lengths. Using oil to fill the gap between the bar stock and the feed tube, the Mini-Rhinobar reduces shop noise levels. As the bar turns, hydrodynamic forces move it toward the center of the tube. Centering forces increase as bar speed increases. Lexair Inc.www.lexairinc.com Enter 596

Elastomer seals

Temperatures to 300F
