Avenger? Genie? Tornado? Help me choose!

Deciding which of our filter products is best for you might seem a little overwhelming when looking at all that A+ has to offer. Let us first begin by breaking it down by what is being sampled. Read below to learn the differences between all of our filters and find out which is the most appropriate to install in your particular sampling system.



Gas Sampling

Prior to the invention of the Genie®, the analyzer community constantly battled the chronic problems associated with liquids getting into gas analyzers because coalescing filters were the only technology available for removing liquids from a gas stream. Although coalescing filters are well suited to remove the bulk of liquids in a gas stream, they have difficulty removing all of it. A coalescer collects liquid on the downstream side of the filter media, where it’s almost impossible to prevent it from becoming re-entrained in the stream.

The Genie® 100 Series was developed specifically to protect gas analyzers from liquids entrained in a sample stream. The Genie® separates the liquids from the gas on the upstream side of the membrane making it much more effective for analyzer protection. It’s quite common for a Genie® to be called a filter, however, technically it’s a Membrane Separator. The Genie® membrane is also a very effective particulate filter. It may, however, load very quickly with particulates because it has much less surface area than a conventional filter media.

In circumstances where there is an excessive amount of liquid or particulate in the gas sample, an Avenger™ coalescing or particulate filter may be required upstream of the Genie®. You should always have a Genie® installed at the inlet of any gas analyzer, however, you don’t always need an Avenger™. On the other hand, if there is so much liquid that you need an Avenger™, then you also need a Genie®. When specifying a Genie®, it’s almost always a good idea to include the Liquid Block™ option.

Genie® Series 100 Comparison Chart is available to help you choose the Genie® model appropriate for your application. The Product Sheet for each model contains the information for detailed specification.


Gas or Liquid Sampling

The Avenger™ Series of filters are used to coalesce liquids from a gas stream or to remove particulates from either a gas or a liquid stream. The primary difference between the 90 series and the 30 series is pressure rating and size. The 90 series offers more filter element options and higher pressure ratings. The 30 series provides a larger filter element. The 33M & 38M contain both a coalescing filter element and a Genie® membrane separator. The primary difference is that the 33M includes a larger membrane and it has larger ports.


Liquid Sampling

Series 200 Models are used separate immiscible liquids, most commonly to remove free water from refined hydrocarbon products such as gasoline, kerosene, diesel, etc.

The Tornado™ is a self-cleaning particulate filter designed to remove hard particulates from liquid streams. Inlet and bypass ports are intended to be in a fast loop to provide enough flow rate to support self-cleaning. The Tornado was developed to be easier to maintain than other self-cleaning filters available at the time. The minimum bypass flow rate is approximately 6 liters/minute (~1.5 gpm). Minimizing the outlet flow rate helps the filter self-clean and reduces maintenance.
