Anderson Separators — Vane Type
Vane Separators — Series AVS
100% Removal of Liquid Particles 8 Microns & Larger · Low Pressure Drop
Anderson® Vane Type Separators
Anderson vane type separators use corrugated profile blades within a receiver for linear flow applications. Removes virtually all entrainment 8 microns and larger from vapor or gas lines. Available in AVS, AVGS, and AVSH models. ISO 9001 Certified.
Anderson vane type separators contain corrugated profile blades (vanes) within a receiver, built specifically for linear flow applications removing virtually all entrainment 8 microns and larger from vapor or gas lines. Entrainment-laden flow is directed into the vanes where it is split into individual vertical streams. A series of short-radius turns within close proximity utilize inertial forces to trap heavier liquid droplets.
Collecting as a film on the profile blades, the liquid flows along the blade and into liquid-collecting pockets where it drains into a collecting sump. The low drag coefficient of the profile design permits handling of high velocities without excessive pressure loss.
Principle of Operation
The success of the Anderson Separation Vane is rooted in simple physics: centrifugal force, impingement, and gravity. The liquid-laden gas entering the vane separator is a mixture of low-density gas and high-density liquid. As the mixture passes through the vane bundle, it is forced to change directions several times. The low-density gas can easily negotiate this path, but because of momentum, the high-density liquid is unable to change direction without impinging upon the vane wall.
Design Flow
0–110% rated flow
No loss or risk of carry-over
Turndown
To ~10% of design
Before re-entrainment risk begins
Efficiency
100% at 8.0 µm+
Optional coalescer achieves 3.0 µm
Features & Construction
Optional Inlet Coalescer
Separation efficiency can be improved to 100% of 3.0 microns by the addition of an inlet coalescer. The coalescer increases the size of incoming liquid droplets so they can be removed by the separation vanes. The inlet coalescer can be either a special hookless vane bundle located in the inlet nozzle, or a stainless steel wire mesh pad mounted on the vane face.
