Thursday, 28th May, 2020 - Meissner Filtration Products announced today that their new manufacturing facility in Co. Mayo is operational. The new facility features a state of the art 930 m² (10,000 ft²) ISO class 7 cleanroom dedicated to the manufacture of Single-Use Systems.  Validation of the facility was completed in mid-April and the facility is currently manufacturing products for their biopharmaceutical and pharmaceutical client base.

“While we had envisaged marking this day with a ribbon cutting ceremony to recognize the efforts of all those involved in bringing this new facility online, this is obviously not possible given Covid-19,” stated Nigel Cannon, Managing Director of the new site. “This symbolic day will come, but what is of immediate importance, perhaps now more than ever given the current health crisis, is that Meissner has an additional operational manufacturing facility capable of supplying our clients with products critical to the manufacture of life saving medicines including those directly related to Covid-19.”

Meissner’s new manufacturing facility is over 3900 m² (42,000 ft²), and future expansion plans call for a substantial size increase over the coming years. Initial ground work for this development is set to begin later this year. Meissner anticipated future expansions at the time of purchasing the new Advanced Technology Building from the IDA, by also purchasing the adjacent land.

With the facility now operational, Meissner had looked forward to welcoming visitors to their new manufacturing site, however Covid-19 has impacted these plans.  “While the site is currently fully operational and otherwise ready for customer visits, as a critical supplier to the pharmaceutical industry, it is of primary importance that all of our sites remain operational, and thus, Meissner Ltd. in Castlebar is not currently allowing outside visitors,” stated Laura Meissner, Executive Director of Quality at Meissner. “While site visits are not yet possible, we have been actively working with our clients to allow them to remotely review the facility operations and validation thereof prior to a physical visit. Contemporary technology has allowed us to still move forward in spite of the current restrictions.”

Congratulating Meissner on this significant milestone, Martin Shanahan, CEO IDA Ireland said, “Just over a year ago, Meissner, in partnership with IDA Ireland, announced its ambitious plans for this manufacturing facility in Castlebar. Now operational, the facility is providing products to its clients in the pharmaceutical and biopharmaceutical sector at this critical time. Meissner continues to create excellent employment opportunities in addition to making an important contribution to the local economy in the West of Ireland. I wish the teams both in Castlebar and in California continued success and the ongoing support of IDA Ireland.”

Meissner wishes to thank all those involved in bringing the Castlebar site online, on schedule, and looks forward to welcoming visitors to the facility as soon as the situation permits.
