88A0330 Panel Ventilation Air Filter Cartridge

I. Model Interpretation:
Brand: Xuman
Type: 88A0330Air Filter Element (Air Filter)

Application: Mainly used for engineering machinery and equipment such as loaders and excavators.
Common applicable equipment examples (specific confirmation required based on equipment model):
Loader: Suitable for series loaders (e.g., models like 856H, 862H, 866H).
Excavator: Suitable for certain specific models of excavators.

II. Key Parameters:
1. Application Location: High-pressure oil circuit (usually installed at key positions such as pump outlet, before valve block, etc., to protect precision valve components).
2. Filtration Accuracy: 20 μm (microns).
3. Sealing Material: Fluororubber.
4. Structural Feature: Equipped with a bypass valve (when the filter element is clogged and the pressure difference increases, the bypass valve opens to ensure uninterrupted oil supply to the system, although the oil is not filtered, providing safety protection).

III. Technical Features and Functions:
1. High-Efficiency Filtration: Utilizes high-quality filter media (typically glass fiber or composite fiber) with high dirt-holding capacity and filtration efficiency, effectively removing solid particulate contaminants from the hydraulic system.
2. Robust Structure: Metal end caps and skeleton ensure the filter element maintains structural integrity under high pressure and pressure fluctuations, preventing collapse or damage.
3. Bypass Valve Protection: The built-in bypass valve is a safety design to prevent system pressure buildup or oil pump damage when the filter element is completely clogged.
4. Good Compatibility: Fluororubber sealing rings are compatible with almost all types of hydraulic oil and can operate stably at higher temperatures.
IV. Application Areas:
This filter element is widely used in various industrial equipment with hydraulic systems, such as: injection molding machines, machine tools (machining centers, stamping machines), engineering machinery (excavators, cranes, loaders), metallurgical equipment, marine and offshore equipment, hydraulic pumps, valves, motors, transmission and control systems.
V. Replacement Precautions:
Replacement Cycle: Not solely based on time. The basis is:
1. Pressure Difference Indicator: Many filters come with a clogging indicator (signal device); when the pointer enters the red zone or pops out, it indicates the need for replacement.
2. Oil Contamination Level Testing: Regularly sample and test the hydraulic oil to determine whether replacement is needed based on the contamination level.
3. Equipment Operating Time: Refer to the maintenance cycle recommended by the equipment manufacturer (usually around 2000 working hours, but must be combined with working conditions).
Replacement Operation:
4. Shut down and relieve system pressure.
5. Clean the area around the filter housing to prevent contaminants from entering the system.
6. Dispose of the old filter element and examine its residue, which may help assess internal wear in the system.
Before installing the new filter element, apply a small amount of clean hydraulic oil to its sealing ring, then hand-tighten until the sealing ring contacts the mounting seat. Do not overtighten with tools. After replacement, start the equipment and check for leaks.
7. Equivalent Replacement Models
Some other brands may offer equivalent replacement products, but be sure to verify all parameters such as dimensions, accuracy, pressure rating, and bypass valve opening pressure.88A0330is a high-quality hydraulic filter element designed for high-pressure pipelines, with a precision of 20 microns, equipped with a bypass valve and fluororubber sealing ring, essential for protecting your hydraulic system.
