Filter C1900004011 is a critical oil filtration component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground ore mines, high-altitude hard rock quarries, large-scale tunnel boring projects and dusty construction sites.
These settings pose unique challenges: hydraulic oil contamination from rock dust, metal particles, and moisture, which causes component wear and system failures. Yet, Filter C1900004011 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations and lead to costly downtime.
First, its glass fiber + stainless steel composite filter element achieves 10μm precision filtration. This eliminates micro-impurities that cause cylinder and valve wear. Second, it supports 80L/min high flow rate without pressure loss. Consequently, it ensures sufficient oil supply for high-intensity drilling operations. Third, its 99.8% filtration efficiency traps almost all contaminants. Likewise, this extends the service life of hydraulic pumps, motors and other key components.
Fourth, the anti-clog surface treatment and large dirt-holding capacity (50g) reduce replacement frequency. Above all, this minimizes maintenance downtime in remote mining areas. Fifth, the corrosion-resistant filter housing (304 stainless steel) and sealed design block moisture ingress. On top of that, it resists chemical erosion from hydraulic oil additives and humid underground air.
Unlike ordinary hydraulic filters, this model is engineered for mining-specific contamination scenarios. To elaborate, the glass fiber layer captures fine particles, while the stainless steel mesh provides structural support. Thus, it outperforms standard filters in service life by 140%, significantly reducing hydraulic system maintenance costs.
Our manufacturing team uses precision pleating + ultrasonic welding technology for filter elements. Furthermore, each unit undergoes bubble point testing and flow resistance verification. Additionally, the filter housing undergoes pressure testing to 25MPa, ensuring no leakage in high-pressure systems.
Notably, it adapts to extreme temperatures from -40°C (high-altitude cold regions) to 120°C (high-load hydraulic systems). Moreover, it passes 400-hour salt spray tests with no rust or housing deformation. In addition, it endures 2,000-hour continuous filtration trials without clogging or efficiency degradation.
The filter’s thread-on connection design integrates seamlessly with mainstream Hydraulic Rock Drill hydraulic systems. It requires no modifications to existing pipelines. As a result, maintenance teams can complete replacement in 10 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform filtration precision tests, flow rate measurements, pressure resistance trials and corrosion resistance inspections. Importantly, it complies with ISO 16889 international hydraulic filter standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its high efficiency, it reduces hydraulic component failure rates by 92%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 58%.
It not only extends hydraulic system service life by 95% but also ensures clean oil supply for stable drilling. Overall, Filter C1900004011 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by oil contamination, maximizing operational efficiency and project profitability.
