This Air Filter is a core intake filtration component designed for the hydraulic systems and oil tanks of heavy-duty machinery, including excavators, loaders, and mining crushers. Typically mounted on top of the hydraulic reservoir or intake piping, it acts as the "lung guard" of the equipment. Its primary function is to balance internal tank pressure while intercepting dust and debris drawn in with airflow. In the harsh, high-dust, and high-vibration conditions of mining operations, this filter effectively blocks contaminants from invading the hydraulic system, preventing wear and jamming of precision components (such as piston pumps and control valves), ensuring the equipment remains powerful and operates smoothly.
Galvanized Carbon Steel Stamped Housing:
The outer shell is stamped from high-quality carbon steel, offering a robust structure with strong impact resistance. The surface undergoes galvanization, forming a dense zinc coating. This not only effectively resists chemical corrosion from acidic mine water, mud, and hydraulic oil—preventing housing perforation or rust flaking that could contaminate the fluid—but also adapts to the long-term vibrational environment of the machinery.
Polished Stainless Steel Filter Screen:
The core filtration medium is made of polished stainless steel mesh. Compared to paper filters, stainless steel mesh offers superior strength and high-temperature resistance, resisting rupture or deformation. The polishing process creates a smooth surface that resists sludge adhesion, making it easy to clean and reuse. The multi-layer folded design provides a massive filtration area, ensuring excellent air permeability and low flow resistance, allowing the tank to breathe freely without causing oil starvation or cavitation due to excessive vacuum.
Rubber Sealing Gasket:
The base is equipped with an oil-resistant rubber sealing gasket. This gasket offers excellent elasticity and compression set resistance, tightly conforming to the mounting flange to ensure an airtight seal and prevent unfiltered air from bypassing the filter element through gaps.
High-Precision Filtration Efficiency:
The product delivers high filtration precision to effectively capture fine airborne particles. Hydraulic oil is the lifeblood of the equipment; even micron-sized dust particles can act as an abrasive paste, accelerating wear on pumps and valves. By efficiently filtering out contaminants, this breather significantly extends the service life of both the hydraulic oil and core components, reducing the frequency of major overhauls.
Wide Environmental Adaptability:
Designed for durability, the filter performs reliably in both freezing cold and scorching heat. The mesh will not become brittle and crack in low temperatures nor soften and collapse in high temperatures, ensuring stable performance in mining and construction sites worldwide.

We strictly adhere to manufacturing standards for fluid filtration components. Every filter undergoes visual inspection and flow testing before dispatch to ensure a crack-free housing, undamaged mesh, and perfect sealing, providing customers with reliable intake purification solutions.
Installation Recommendation:
Clean the tank mounting flange before installation. Avoid over-tightening to prevent damage to the housing threads or gasket. It is recommended to inspect the mesh every 500 working hours; if excessive dust accumulates, clean it with compressed air or kerosene for continued use.
