Ayater 301/381 Series ASME Filter Assemblies

Product Introduction

As a professional filtration solutions provider, Ayater engineered the 301/381 Series ASME Filter Assemblies specifically for high viscosity lubricating oil filtration scenarios. Compliant with strict ASME standards, these filter assemblies are designed to address the challenges of filtering high-viscosity fluids (ISO VG 100-460), which are commonly used in heavy-duty industrial equipment where precise lubrication and contaminant control are critical to operational reliability.

The Ayater 301 Series ASME Filter Assembly is optimized for medium-to-large flow industrial systems, featuring a compact design that balances filtration efficiency and installation flexibility. It is ideal for general high viscosity lube oil applications such as industrial gearboxes, hydraulic power units for heavy machinery, and turbine lubrication systems. Equipped with Ayater's proprietary high-efficiency filter media, it effectively captures solid contaminants down to 5μm, preventing abrasive wear to critical components and extending equipment service life.

The Ayater 381 Series ASME Filter Assembly is tailored for heavy-duty, high-pressure high viscosity lubrication systems. Its robust housing structure and enhanced sealing technology ensure stable performance under extreme operating conditions, such as high-temperature industrial furnaces, large-scale compressor lubrication systems, and offshore drilling platform machinery. With filtration precision options down to 3μm, it provides ultra-clean lubricating oil to protect high-value, high-precision industrial equipment.

Both series adopt a user-friendly quick-release element design, enabling efficient301/381 filter element replacement without complex tools, significantly reducing maintenance downtime. Ayater's exclusive filter media enhances dirt-holding capacity by 45% compared to standard alternatives, prolonging filter service cycles and lowering overall operational costs.
