High-Flow Heavy-Duty Solutions (9901 Series)

When managing large volumes of fluid under high pressure, standard filters often fail to balance efficiency with flow stability. The Ayater 9904 series is specifically developed for high-flow applications (up to 450 L/min) where system uptime is non-negotiable. This series provides a robust, serviceable solution for the most demanding industrial environments.

9901 Series Advantages

1. Stable Pressure Resistance: 38MPa rating ensures reliable operation in medium-high pressure systems without leakage or deformation.

2. Precise Contaminant Removal: 4μm filter element eliminates fine particles, extending component lifespan by 42% compared to conventional filters.

3. Easy Maintenance: Tool-free 9901 filter element replacement reduces maintenance time by 50%, lowering downtime and labor costs.

4. Low Pressure Drop: Optimized flow channels control pressure drop to ≤0.08MPa, ensuring smooth oil supply and system efficiency.

 

9904 Series Advantages

1. Ultra-High Pressure Bearing: 55MPa rating handles extreme pressure in super heavy-duty systems, with forged steel housing preventing deformation.

2. Ultra-Precise Filtration: 2μm filter element removes ultra-fine contaminants, protecting high-precision components from irreversible damage.

3. Extreme Environment Adaptability: Forged steel housing and Viton seals resist corrosion, low temperature, and high heat-ideal for harsh industrial scenarios.

4. Safe & Efficient Maintenance: Sealed quick-release 9904 filter element replacement ensures safe operation in high-pressure environments, cutting maintenance time by 55%.

FAQ

 

 

01.What makes Ayater 9901 and 9904 filters stand out in terms of maintenance efficiency

Both series feature user-friendly maintenance designs. The 9901 filter adopts a tool-free quick-release structure for element replacement in just 2 minutes, reducing maintenance time by 50%. The 9904 filter is equipped with a heavy-duty sealed quick-release locking structure, ensuring safe and fast replacements even in ultra-high pressure environments, cutting maintenance time by 55%. These designs minimize equipment downtime and lower labor costs significantly.

02.How do Ayater 9901 and 9904 filters ensure reliable performance in different working conditions?

Ayater optimizes the two series for diverse industrial environments. The 9901 filter with high-strength cast aluminum alloy housing and NBR seals operates stably at -18℃ to +115℃, suitable for automation lines and light construction machinery. The 9904 filter uses high-strength forged steel alloy housing and Viton seals, adapting to extreme conditions of -25℃ to +135℃, corrosion, and ultra-high pressure, making it ideal for offshore platforms and mining excavators.

03.Why are Ayater 9901 and 9904 filters beneficial for prolonging hydraulic system lifespan?

The precise filtration and stable pressure control of Ayater filters are key to extending system lifespan. The 9901 filter's 4μm element eliminates fine particles, extending component lifespan by 42%. The 9904 filter's 2μm ultra-precise element removes ultra-fine contaminants to avoid irreversible damage to high-precision components. Additionally, their low pressure drop designs (≤0.08MPa for 9901, ≤0.1MPa for 9904) ensure smooth oil circulation and uncompromised system efficiency.
