769144 ABB Disposable Filter

769144 is an ABB Disposable Filter used in the sample gas path of ABB continuous gas analyzer systems. ABB documentation describes it as a pre-assembled micro-porous filter or fine filter, positioned at the sample gas inlet to filter the incoming sample gas before it enters the analyzer.

The component is supplied as a ready-to-install filter assembly with flexible tubing connections. ABB documentation identifies 769144 as a one-way/disposable filter and specifically excludes Fidas24 applications.

The 769144 filter is associated with ABB gas analysis equipment rather than general-purpose industrial filtration. ABB installation documentation for the EasyLine EL3000 series specifies the pre-assembled filter as part of the sample gas connection arrangement. The same documentation instructs that the short flexible tube is connected to the analyzer's sample gas inlet, while the sample gas line is connected to the longer tube with the hose nozzle.

ABB documentation for the AO2000 series also lists disposable filter 769144 in the standard scope of supply and delivery. The document again specifies that this filter is not intended for Fidas24 and Fidas24 NMHC versions.

The filter sits directly in the sample gas route. Its purpose within the analyzer's gas-handling arrangement is to provide filtration before the sample reaches the analyzer.

For the EasyLine installation arrangement, ABB specifies:

• Connect the short hose section to the sample gas inlet.
• Connect the sample gas line to the longer hose section.
• Use the filter as part of the sample gas connection.
• Install the flow meter or flow monitor upstream of the sample gas inlet when required.

These instructions are part of ABB's published gas-line installation procedure.

ABB documentation associates 769144 with several continuous gas analyzer configurations. Confirmed references include:

The exact analyzer version should be checked before replacement because ABB explicitly excludes Fidas24 from the 769144 filter application.

769144 is a consumable rather than an electronic analyzer module. Its replacement should therefore be considered part of sample-gas-path maintenance.

When identifying a replacement, the most useful references are:

• ABB part number: 769144
• Description: Disposable Filter
• Filter designation: micro-porous / fine filter
• Installation point: sample gas inlet
• Analyzer family: EasyLine EL3000 or compatible ABB gas analysis equipment
• Exclusion: Fidas24

Do not substitute a generic filter solely because it has a similar physical appearance. The analyzer's sample-gas connection arrangement and the specified ABB part number should be checked first.

Important Application Note

 

 

ABB's current and historical installation documentation uses slightly different terminology for 769144. Depending on the document, it is described as a "disposable filter," "micro-porous filter," "fine filter," or "one-way filter." These descriptions refer to the same ABB order number in the cited analyzer documentation.

 

ABB also states that the filter is supplied pre-assembled or preinstalled in the applicable analyzer configurations. This means 769144 should be treated as a complete filter assembly rather than assuming that only an internal filter medium is being supplied.

What is ABB 769144?
769144 is an ABB disposable filter used in the sample gas path of compatible ABB gas analyzer systems.

Is 769144 a micro-porous filter?
Yes. ABB EasyLine documentation describes 769144 as a pre-assembled micro-porous filter, while other ABB documentation describes it as a fine or one-way filter.

Where is 769144 installed?
It is installed at the sample gas inlet as part of the analyzer's sample gas connection.

Which ABB analyzers use 769144?
ABB documentation identifies 769144 with EasyLine EL3000-series configurations and AO2000 gas analyzers, among other compatible arrangements.

Can 769144 be used with Fidas24?
No. ABB specifically states that disposable filter 769144 is not for Fidas24; the AO2000 documentation also excludes Fidas24 and Fidas24 NMHC.

Is 769144 an electronic component?
No. It is a mechanical filtration consumable used in the sample gas path of ABB analytical equipment.

Does 769144 come pre-assembled?
ABB documentation describes the filter as pre-assembled or preinstalled in the applicable analyzer configurations.

What should be checked when replacing 769144?
Confirm the ABB part number, the analyzer model, the sample gas connection arrangement, and whether the application is excluded by ABB. In particular, Fidas24 should not be matched with 769144.

For this component, 769144 is the primary identification code. Use the description ABB Disposable Filter together with the analyzer model when matching the replacement.

Because ABB's published documents do not provide a complete standalone specification sheet for 769144, filtering performance values, dimensions, materials, and other unverified characteristics should not be assumed from generic disposable-filter products. The ABB order number and compatible analyzer documentation remain the key matching references.
