150 new jobs are to be created in Co Mayo by an American firm, as part of its first expansion outside of the US.
Meissner Filtration Products is setting up a manufacturing facility in Castlebar and will fill the positions over the next five years.
The company says it will be operational in early 2020 and that the initial number of jobs is a conservative estimate of the potential for employment in the west.
Meissner has acquired a building that was constructed by IDA Ireland in Castlebar and it plans to triple the size of its operation in the town in due course.
The company's founder, Chris Meissner, said the availability of a new 34,000 square foot facility significantly reduced the set-up time for its Irish expansion.
The site was chosen following a detailed analysis of a number of prospective locations around Europe.
The announcement is seen as a boost for the Co Mayo town and comes after a number of similar announcements in recent years failed to deliver on the numbers of jobs promised.
The IDA has constructed a number of so-called Advanced Technology Buildings on sites around the country.
These provide adaptable premises that can be specifically tailored to the particular requirements of different industries.
The agency's Executive Director, Mary Buckley, said today's announcement was a vote of confidence in the initiative and an indication of the investment potential in the regions.
