Element Design & Construction The LGS Series filters offer a high efficiency coalescing style element. Each model employs one or more of these replaceable element cartridges which provide positive gasket sealing to prevent by-pass of unfiltered gases. Long filter life, low pressure drop, and efficient filtration and coalescing action are assured. This coalescing action is simply a "gathering" of minute liquid particles or smaller droplets to form larger droplets. The small droplets that enter the inside of the element are intercepted or impinged by the filter media and extracted from the gas stream. The larger droplets once formed, drain off the outside of the element and fall by gravity to the sump area in the filter housing where a drain connection is provided for removing the coalesced liquid. The high efficiency element prevents re-entrainment of liquid downstream. The coalescing/ draining action continues at the same rate that new liquid enters the element, allowing long service life before element replacement is required. The LGS Series filters are designed to handle liquid concentrations up to 1000 ppm and are capable of providing downstream air having less than 5 ppm of liquid. Dew point remains unaffected by the coalescing action. Element Materials Standard elements are composed of extremely fine borosilicate glass fibers with a resin binder, in a cylindrical, depth-type design. LGS Series elements may be used in service temperatures up to 200° F, and an optional element style permits high temperatures up to 400° F in continuous service and 450° F intermittently. Standard elements are furnished with plated steel center core and end caps. Stainless steel and other materials are also available. Housing Design and Construction Housings are designed and constructed in accordance with ASME Code Sec. Vlll Division I requirements for unfired pressure vessels (6 1/4" diameter and above). Models LGS 115 and above are available with "U" stamp registration and certification. All models can be quickly serviced without breaking pipe connections. Models LGS 120 and up are furnished with 1/4" NPT gauge connections on the inlet/outlet nozzles. Standard models LGS 130 and above are furnished with leg supports. Model LGS 160 has a hinged closure device, and Models LGS 170 and above are equipped with a davit lifting device for cover removal. Standard filter housings may also be modified or customized to meet unique or special application needs. Typical design modifications include: special leg lengths, end connection types, inlet/outlet orientations, modified closure styles, and special controls and accessories. Special gasket and element materials will allow the filter vessel to be applied in service conditions up to its maximum design of 180 psig at 466° F.
