Function of the ABB 1949790A1 Fan Filter Assembly

The ABB 1949790A1 Fan Filter Assembly combines ventilation and filtration functions in a single assembly for compatible ABB industrial control installations.

Cooling is an important consideration in industrial control cabinets because power supplies, controllers and other electronic equipment generate heat during operation. A fan assembly provides forced airflow, while the filter section helps manage the air entering or leaving the enclosure.

ABB’s MPS III documentation distinguishes the 1949790A1 Fan Filter Assembly from the PHARPSFAN03000 System Monitoring & Cooling Fan and PHARPSCH100000 Power Supply Chassis, so the complete product number should always be checked when sourcing a replacement. ABB Library

ABB MPS III Related Components

ABB documentation lists the following accessories together in its MPS III active power system component information: ABB Library

ABB also lists power supply modules including PHARPS03000000, PHARPS32000000, PHARPS32010000, PHARPS32200000 and PHARPS40000000 in the same MPS III component documentation. ABB Library

These different components perform different roles. Therefore, customers should not select a replacement component based only on physical appearance.

1949790A1 and PHARPSFAN03000 – What Is the Difference?

The two part numbers are related to system cooling, but ABB lists them as separate products.

1949790A1 is identified as a Fan Filter Assembly, while PHARPSFAN03000 is identified as a System Monitoring & Cooling Fan. ABB Library

If an existing installation requires replacement of the fan/filter assembly, verify that the identification label shows 1949790A1. If the existing component is the system monitoring and cooling fan assembly, check whether the required part number is PHARPSFAN03000.

Providing a photograph of the existing product label can also help reduce the possibility of selecting the wrong replacement component.

Applications of ABB 1949790A1

The ABB 1949790A1 can be used in compatible industrial automation and control system installations requiring cabinet ventilation and filtration.

Typical requirements can include maintenance of existing ABB control systems, replacement of installed cooling components, plant shutdown maintenance, control cabinet refurbishment and stocking spare parts for installed automation systems.

Because industrial control equipment may remain in operation for many years, matching the exact part number is particularly important when sourcing replacement hardware.

How to Identify the Correct 1949790A1

Before requesting a quotation, inspect the identification label on the existing component and confirm the complete part number:

1949790A1

Do not rely only on the shape, fan dimensions or appearance of the front grille. Industrial fan and filter assemblies can look similar while having different electrical or installation requirements.

For uncertain applications, customers can send YULI Automation a clear photograph of the existing component and its identification label together with the required quantity.
