Desiccant filter breathers are being used more and more to trap moisture before it gets into a hydraulic reservoir. Although effective, they do not necessarily offer a permanent solution. That’s because the desiccant eventually becomes spent, and unless the desiccant or the entire unit is replaced, moisture will again be drawn into the reservoir....More

You can find special-purpose vehicles for almost every task of landscape gardening – from riding lawn mowers to equipment trailers. These vehicles are normally designed for relatively flat and level fields, so an operator confronting a steep slope can pose a real challenge. A solution to this problem is a system similar to auto-leveling systems found in combine harvesters. For mowers, the chassis and mower unit remain parallel to the ground’s surface while the operator pod stays level. The result is safer and more comfortable mowing on slopes....More

HR-Series regenerative air dryers consist of two towers containing a molecular sieve desiccant bed for adsorbing moisture from compressed air. The re-pressurization portion of the dryer cycle allows each desiccant tower to restore the full line pressure before it is switched online....More

Cool Loop offline filtration and cooling system conditions fluid and provides high heat transfer in a small size while limiting pressure drop. Compact, lightweight screw pump is quiet and provides max flow to 45 gpm....More

Series 21 direct acting solenoid operated valve features O-ring ports to eliminate leakage; enclosed solenoids and connections reduce exposure to elements, and individual load checks are built into each section. Can becombined with series 20 manual valve for increased versatility. Includes 6 gpm nominal capacity, pressure ratings of 4000 psi (272 bar), parallel and 3000 (204 bar), series....More
