Higher flow rate filters, all available with 1/4″ or 1/2″ NPT ports. The 33G and 45G are supplied with a Pyrex glass bowl complete with external plastic shield. These housings are especially useful for gas sampling when a large volume of condensed liquid is expected.

The model EU27 and 15/80S6 housings are among the largest 316 stainless steel filters available with high-pressure capability.

Parker fast loop filters are constructed of 316 stainless steel with an optional stainless steel or pyrex bowl. This flow through design continuously flushes the filter cartridge carrying the contaminates back out to the process stream, thus maximizing the filter cartridge life.

The series 39 and 98 membrane filters consist of a housing with a porous PTFE membrane filter, which is supported by a sintered porous disk located on the “outlet” side of the housing.

The Balston Coalescer Membrane Combination Filter is designed to remove entrained liquid and particulate in gas samples for a wide variety of applications and thereby prevents contamination or damage to the analysers and sample system components.

The MERLIN Cyclone Separator is an innovative and patented multistage separation technology that protects on-line gas analyzers by preventing arrival of liquids and solid particulates.

The GPR™ consists of a housing and a membrane tip probe regulator. The housing is installed in a depressurized pipeline through a vertically mounted thread-o-let or flange, and contains a “foot valve” in its lower end. Inserting the probe into the housing opens the “foot valve”, allowing pipeline gas to flow freely through the membrane. The sample pressure is reduced immediately downstream of the membrane, inside of the pipeline. Heat is transferred from the pipeline to the regulator to prevent excessive Joule-Thomson cooling, which helps prevent condensation during pressure regulation. Retracting the probe from the housing closes the foot valve, making it possible to perform probe maintenance without depressurizing the pipeline. This insertion/retraction method is considerably less expensive and complex than pneumatic or hydraulic methods.

The GP2™ probe consists of a housing and a membrane tip probe. The housing is installed in a depressurized pipeline through a vertically mounted thread-o-let or flange, and contains a “foot valve” in its lower end. Inserting the probe into the housing opens the “foot valve”, allowing pipeline gas to flow freely through the membrane. Retracting the probe from the housing closes the foot valve, making it possible to perform probe maintenance without depressurizing the pipeline. This insertion/retraction method is considerably less expensive and complex than pneumatic or hydraulic methods.

The GPHV™ was designed sampling from high velocity gas streams. The thick walled probe, which is machined from a single piece of stainless steel, has a high natural resonant frequency that allows it to withstand the destructive forces of gases flowing at high velocities. This model must be installed with a depressurized line.

The Model 755™ is an adjustable length, membrane tip probe regulator designed to sample transmission quality natural gas. The pressure regulator is built into the probe immediately downstream of the membrane, inside of the pipeline. Heat is transferred from the flowing pipeline gas to the regulator to prevent excessive Joule-Thomson cooling, helping to prevent condensation during pressure letdown.
