CONSLER LGS SERIES COMPRESSED GAS SEPARATORS
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 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/
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.
