Wright Austin ST and 31L-ST Gas Liquid Separators
Cast Iron separators with integral drain trap for up to 40% by weight of the units flow capacity

This version of Wright Austin cast iron air/liquid separators has an integral drain trap, making it easily installed and very compact. Castings are available with threaded connections as small as 3/4" to 3" in size and with 125# FF ANSI flanged connections 2" to 5" in size.

Following are links to the Wright Austin outline drawings and the pricing table.  The components to build cast iron air/liquid separators are usually stocked items and shipments made within 1 week after receipt of an order.  The lead time for cast air liquid separators when castings are not in stock is typically 6-8 weeks. If the lead time is critical, please contact our office and obtain a lead-time estimate based upon the current manufacturing backlog.  If you need assistance with proper selection, please fill-out our inquiry form.

Low Profile Design
The Type 31L-ST is a horizontal, in-line separator is very compact and can be supported by the line in which they are installed,  an important consideration in space restricted applications.

Integral Drain Trap
All Type 31 L-ST Separators come with standard, integral drain traps. This design saves
space, reduces installation costs and eliminates the need to properly size and source a properly designed drain trap to work with the separator. The integral trap automatically ejects the condensate at predetermined levels without loss of line pressure.

Performance Overview

• ST separators are designed to remove entrained liquid and solids from air, gas or steam.  Their integral drain trap allows fluid to drain from the system without a system pressure drop.  This specific design is effective for applications where the entrained liquid flow rate is up to 40% by weight of the units flow capacity.

• When properly sized, this separator will remove up to 99% of all liquid and solids greater than 10 microns in size from an air, gas or steam flow.  The removal is accomplished by a design that causes the air/gas/steam to enter a controlled centrifugal flow.  This results in forcing the entrained material to the outer wall and the VCP prevents reentrainment.

• Cast iron ST separators are constructed to ASME code for unfired vessels, Section VIII, Division 1.  An ASME stamp and CRN registration is available for sizes 2 inches and larger.
