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 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.
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 model EU27 and 15/80S6 housings are among the largest 316 stainless steel filters available with high-pressure capability.
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 type 85 filter housing is constructed of 316 stainless steel and has a pressure rating of 345 barg. This type can accommodate X-type filter cartridges and is used when a larger quantity of liquid is expected. The T-type filter housings are also constructed of 316 stainless steel and have a 276 barg rating. These types are used as sample filters for on-line sample analysers when a larger line size, higher flow rate or larger bowl reservoir capacity is required.
The T-model filter housings are also constructed of 316 stainless steel, and have a 276 bar rating. These models are used as sample filters for on-line sample analysers when a larger line size, higher flow rate or larger bowl reservoir capacity is required. Model 27 housings are constructed of 316 stainless steel. These models have 1” NPT ports and are rated to 55 bar. The model 27 housings hold a single LP-200 filter cartridge, available in 10” or 20” length.
These types offer compact designs and half the dead volume of other sample filters, resulting in faster sampling times. They are constructed of stainless steel and available with a variety of seals for easy adaptation to demanding applications. If larger amounts of condensate are expected, specify 33 or 45 series.
These miniature T-type filters are constructed of 316 stainless steel, Teflon® and Monel. With only 19ml internal volume and the opportunity for by-pass or slipstream filtration using the drain port as an exit port, the type 95 filters are ideal sample filters for on-line analysers. The type 105S6 has a smaller internal volume of 15ml.
The type 97S6 is a miniature 316 stainless steel filter with 1/4" NPT in-line ports and 345 barg rating. Since the filter does not have a drain port, the type 97S6 is used as an end-of-the-line compressed gas filter when little or no liquid is expected, for example as a cylinder gas filter. Designed specifically for quantitative measurement of solids in gases to 538°C, the filter cartridge and element retainer disk in the type 30 housings may be weighed as a single unit.
Filter housings used with these media: 9922-05; 9933-05; 9922-11; 9933-11; 8833-11; 90; 7700-12; 58P; 53/18; 53/50; 54/50; A98/11; A39/12; 105S6; 91S6; 95M; 95S6; 95A; 95T; 97S6; 30/12; 30/25; 91S6; 31G; 41G; 31S6; 41S6; 33G; 33S6; 45G; 45S6; EU27/35; EU27/35-3000; EU27/80; EU27/80-3000; 15/80S6; EU85; EU37/12; EU37/25; 58N; 38/12; 38/25; A23/75SR; A23/75R; SP3/75SR; SP4-23/75SR; SP6-23/75SR; 6000 series; A34; A33B; A45; A27/35B; A27/80B.
Parker Hannifin Corporation manufactures Balston brand disposable filter units (DFU) which incorporate an extensive media capability with a small, inexpensive, disposable housing. This unique design was introduced to the filtration industry over 20 years ago.
