HYDAC Pilot Filter B222100000451/B222100000116 - Core Guardian of Construction Machinery Hydraulic Systems As the "purification core" of hydraulic systems, HYDAC pilot filters B222100000451 and B222100000116, featuring German original manufacturing technology and strict quality control, are the preferred compatible accessories for construction machinery such as truck cranes, tire cranes, crawler cranes, and truck-mounted cranes. Adopting high-precision glass fiber filter media with a filtration accuracy of 3μm, the products efficiently trap impurities, iron filings, and other contaminants in hydraulic oil, protecting key components like pilot valves and hydraulic pumps from the source, reducing failure rates, and extending equipment service life. Complying with HYDAC's original factory technical standards, the two filter models perfectly match mainstream OEM equipment (e.g., XCMG, Sany, Zoomlion). With easy installation and excellent sealing performance, they ensure stable hydraulic system pressure and sensitive response. Leveraging the industrial cluster advantage of Changsha, the "Capital of Construction Machinery in China," we have established a large intelligent warehousing center with sufficient inventory for immediate delivery. Supported by a global logistics network and 24/7 technical support team, we provide customers at home and abroad with full-chain services from model selection consultation to after-sales support. Choosing our HYDAC pilot filters means not only opting for the reliable guarantee of German quality but also enjoying the dual advantages of efficient supply chain response and professional services, empowering engineering construction to proceed efficiently, safely, and cost-effectively.
