Type 31-LSF

Eaton Gas/Liquid Separators

For extremely fine entrainment removal applications

Computer-generated image of a Type 31-LSF gas-liquid separator.

  Models

Models currently unavailable.

  Features

The two-stage Eaton Type 31-LSF Gas/Liquid Separator/Filter removes 99% of all particles larger than 10 microns and is for applications requiring extremely fine entrainment removal. The first stage is a centrifugal separator that removes slugs and heavy liquid loads. The second stage uses coalescing filters to remove nearly all remaining droplets plus particles as small as 0.3 microns from air, gas, and steam processes.

Features/Benefits

  • Fabricated construction
  • High efficiency over wide flow range
  • Removes 99% of liquid and solid entrainment particles larger than 0.3 microns - dependent on installed filter
  • Gas, steam, or air applications
  • Integral sumps

Options

  • High pressure models
  • ASME U code stamp

Exclusive Design

Moisture-laden gas enters the inlet of the separator where droplets are centrifugally thrown to the outside wall of the vessel by a unique Cenpellar™. The liquid flows to the bottom sump for draining. Eaton’s Vortex Containment Plate (VCP) prevents the droplets from being re-entrained after separation. The clean, dry flow is then directed to the second stage where precision filters capture any additional moisture and particles. A second sump is used to collect and discharge the additional entrainments.

Fabricated Construction

Fabricated Type Type 31-LSF Gas/Liquid Separators/Filters are available in standard sizes from 2-½" to 16" in carbon steel or stainless steel construction. All internal separating elements are 304L stainless steel. Other sizes can be ordered for special applications. Ports are built in for vents, gauges, and drains. Additional fittings can be specified. The filter elements are made of borosilicate microglass fibers, epoxy saturated, with glass-matrix drain layer. Filter elements can be ordered in a range of micron ratings down to 0.5 microns. Eaton Type 31-LSF Gas/Liquid Separator/Filters meet ASME Code, Section VII, Division 1. ASME U code stamp is available.
