US-based speciality gas provider OE Meyer has strengthened operational safety and environmental performance after replacing oil-sealed vacuum systems with dry vacuum technology from Leybold.
Headquartered in Ohio, OE Meyer operates seven locations across the state and is fully owned by its 130 employees. Established in 1918, the company supplies industrial and speciality gases, welding accessories and automation solutions to customers in industry, agriculture, healthcare and gastronomy. Its operations include industrial and medical gas filling, as well as oxygen and inert gas cylinder filling.
The company introduced Leybold’s DRY screw vacuum pumps and oxygen-resistant VARODRY HD/O2 systems in January 2023, targeting improvements in safety, efficiency and cost control.
Previously, oil leaks from conventional vacuum pumps had posed operational challenges. According to Mitch Robinson from OE Meyer, oil leaks created slipping hazards and environmental risks, while oil changes cost around US$1,600 each. The maintenance requirements and contamination risks prompted the company to seek a more sustainable alternative aligned with modern safety and environmental standards.
Leybold’s dry-running technology eliminates the need for oil within the compression chamber, removing the risk of oil contamination and backflow. The VARODRY HD/O2 model is certified for oxygen-rich processes, making it suitable for medical oxygen filling applications and providing additional reassurance for operators working in sensitive environments.
Robinson said the transition has delivered tangible benefits. The new pumps have proven clean, ergonomic and efficient in day-to-day use, while integrating seamlessly into existing processes. The dry systems have also contributed to greater reliability and reduced downtime.
In addition, the switch to Leybold’s DRYVAC dry screw vacuum pumps has improved production performance and extended service life. By minimising contamination risks, particularly in demanding gas filling operations, the systems support higher production yields and consistent product quality.
OE Meyer estimates that the move has resulted in savings of approximately US$10,000 per year in PFPE oil consumption alone. A further US$10,000 in annual savings has been achieved by eliminating maintenance issues linked to oil changes. Despite initial concerns about the transition, the company reports that overall operational efficiency has increased, while the working environment has become cleaner and safer.
Robinson also highlighted positive experiences with Leybold’s service support, noting punctual maintenance visits and practical guidance. For example, changing a belt on the VARODRY system can be completed in around 15 minutes, enabling faster in-house servicing.
The upgrade reflects a broader shift among gas suppliers towards dry vacuum solutions that enhance safety, environmental protection and long-term cost efficiency.
