Introduction
In hydraulic and lubrication systems, maintaining oil cleanliness is crucial for ensuring smooth operation and long equipment life. The MASUDA SEISAKUSHO MST Suction Strainer delivers exceptional reliability and filtration performance with its lightweight aluminum design and precision Japanese engineering. Designed for various industrial applications, the MST series is the ideal choice for users seeking high-quality, easy-maintenance suction filters.

Key Features of the MASUDA SEISAKUSHO MST Suction Strainer
The MST Suction Strainer stands out for its advanced engineering and user-focused design:
Lightweight Aluminum Alloy Body – Crafted from high-strength aluminum, the MST series offers excellent corrosion resistance while keeping installation effortless due to its lightweight construction.
Durable Notch Wire Filter Material – The unique notch wire element design prevents clogging and ensures consistent flow. Its special slit geometry and smooth surface make cleaning easy — simply wipe with a soft cloth or cleaning oil. (Restoration performance: 90–100%)
Superior Air Release and Low Foaming – With high deaeration performance, the MST prevents air entrainment, reducing the risk of pump cavitation or other equipment issues.
Fluid Compatibility and Application Range
The MST Suction Strainer is suitable for multiple industrial fluids, including:
General mineral oils
Phosphate ester fluids
Fatty acid ester fluids
For water-glycol systems, MASUDA recommends using the W-MSN or W-MSY series instead.
This versatility makes the MST ideal for use in hydraulic units, lubrication systems, and various oil circulation setups across manufacturing and energy sectors.
