The vacuum setting of the Model 329 series of vacuum regulators is easily adjusted by turning the control knob, which has a total range of 13 turns, thereby providing very fine adjustment resolution.
L.J. Engineering, Inc.'s Model 329 Vacuum Regulator maintains and controls vacuum within +/-0.01 in-Hg. Its precision-machined aluminum housing, brass, stainless steel, and silicone rubber parts provide a high quality, precision vacuum regulator, which accounts for its use in a wide variety of vacuum control applications. Examples of applications include precision vacuum clamping, low force "pick and place" part handling of delicate materials, low absolute pressure test and calibration systems, vacuum degassing of liquids, cryogenic temperature regulation through low absolute pressure control, altitude simulation chambers, vacuum leak test instrumentation, vacuum bag control, and countless other sub-atmospheric or less-than-atmospheric pressure (vacuum) control situations.
Remote Filter Option
An optional Remote Filter is recommended when the regulator is used in a dusty environment or for continuous operation. The Model 329-500 Vacuum Regulator includes a Remote Filter. This regulator may be used where small particulate matter are present in the surrounding air environment. The Remote Filter attaches to the Model 329 through a short hose and quick-disconnect fitting. The filter is easily removable for cleaning and reuse.
