Customer Cases

1. Product Concept
The A.4-842 is engineered as a high-performance industrial replacement filter element, designed to provide reliable and cost-effective filtration in demanding fluid power and lubrication systems. Its core concept centers on delivering OEM-comparable or superior performance as a direct-fit alternative, ensuring system integrity, protecting sensitive components from particulate contamination, and maintaining optimal fluid cleanliness to support efficient machinery operation and extended service life.

2. Key Features & Advantages

• Optimized Filtration Media: Utilizes high-quality pleated media (e.g., cellulose/synthetic blend) designed to provide consistent particle removal efficiency at its specified micron rating, balancing flow capacity with dirt-holding capability.

• Enhanced Durability: Constructed with robust inner and outer support cores to resist collapse under high differential pressure and ensure structural stability throughout its service life.

• Superior Seal Integrity: Incorporates precision-engineered sealing gaskets (typically Nitrile rubber) to prevent bypass and guarantee a leak-free fit in compatible filter housings.

• Extended Service Intervals: The high dirt-holding capacity maximizes the time between change-outs, reducing maintenance frequency, downtime, and total operating costs.

• Direct Replacement Design: Manufactured to precise dimensional and performance specifications for easy, hassle-free installation as a drop-in cartridge in designated OEM housings.

3. Application Areas
The A.4-842 is a versatile filter element suitable for a wide range of industrial applications where dependable particulate filtration is critical, including:

• Hydraulic Systems: Protecting pumps, valves, and actuators in industrial machinery, presses, and mobile equipment.

• Lubrication & Bearing Circuits: Ensuring clean oil in gearboxes, compressors, turbines, and circulating oil systems.

• Industrial Process Fluids: Filtration of coolants, washing fluids, and other process liquids in manufacturing and metalworking operations.

• Mobile Off-Highway Equipment: Used in construction, agriculture, and forestry machinery operating in harsh, high-contamination environments.

• General Plant Maintenance: Serving as a reliable replacement filter across various industrial maintenance programs for fluid system upkeep.
