Air Products adds 70 jobs in $70M Maryland Heights expansion

Air Products Membrane Solutions has completed a $70 million expansion of its manufacturing and logistics center in Maryland Heights, Missouri. The investment, which represents the division's largest single-location expansion to date, brings more than 70 new jobs to the St. Louis region and increases the site's total headcount to over 250 employees.

The expanded capacity is designed to capture growing industrial demand for specialized gas separation equipment. The Maryland Heights facility will scale up production of PRISM Membrane Separators. These systems are critical components in supply chains across the aerospace, marine, and biogas sectors.

Industrial Demand and Supply Chains

Advanced manufacturing is increasingly focusing on domestic capacity for core industrial components, and the Air Products investment fits directly into that trend. The equipment produced in Maryland Heights serves a dual purpose: improving efficiency for traditional aerospace needs and supplying the infrastructure required for broader industrial transition, specifically in biogas.

The project underscores the regional economic ripple effects of global industrial shifts. By anchoring the production of these high-demand membrane separators in Missouri, Air Products is reinforcing the Midwest's role in the specialized manufacturing supply chain.


Local Economic Impact

The completion of the expansion was marked by a ribbon-cutting event attended by state and local officials, including representatives from the Missouri Department of Economic Development and Maryland Heights Mayor Mike Moeller.

Beyond the direct hiring of manufacturing and logistics personnel, the Air Products Foundation announced $30,000 in local grants to support regional nonprofits, including Backstoppers and The Foundation for Barnes-Jewish Hospital, further embedding the company's footprint in the St. Louis area ecosystem.
