The JOS Series uses precision-machined rotary vanes operating within an oil-sealed chamber. The oil ensures tight sealing and efficient heat dissipation, allowing the pump to achieve consistent high vacuum levels with reliable pressure control.

The JOS Series is commonly used in laboratory and research setups, vacuum coating and surface treatment, packaging and degassing, drying and heat treatment, and pharmaceutical or chemical processes that require clean and stable high vacuum.

Yes. The JOS Series is designed for both continuous and intermittent duty cycles. Optimized oil circulation, robust internal components, and effective lubrication help minimize wear and maintain stable performance over extended operating hours.

Oil-sealed pumps provide better sealing and higher achievable vacuum levels compared to many oil-free technologies. They are well-suited for clean and controlled environments where precise vacuum and stable pressure are required, while oil-free pumps are typically preferred for contamination-sensitive processes.

Routine maintenance includes monitoring and replacing vacuum oil, checking filters and seals, and ensuring proper operating conditions. Regular maintenance helps maintain vacuum performance, extend service life, and ensure reliable operation.

Selection depends on required vacuum level, pumping speed, process cleanliness, duty cycle, and operating conditions. JOYAM’s engineering team evaluates these parameters to recommend the most suitable JOS Series configuration for consistent and efficient operation.
