In the long-term operation of engineering equipment, high-quality filters are the key to ensuring the stability of the power system. The entire series of Wittgen filters, with their original factory grade quality, have become the core compatible accessories for equipment such as rollers, milling machines, pavers, and cold recycling machines. Ningbo Qiuning Trading provides cost-effective supply solutions for bulk purchasing customers.
This series of filters covers the requirements of mainstream Wittgen models, including four categories: oil filters, air filters, fuel filters, and fuel water separators. It can accurately adapt to Wittgen W series milling machines, H series rollers, SP series pavers, CR series cold regeneration machines, and other equipment. Compared with ordinary products, it adopts imported composite filter materials and uses a multi-layer gradient filtration structure to efficiently intercept dust in the air, impurities in the fuel, and metal debris in the engine oil. The air filter has a filtration accuracy of 1 μ m, and the fuel filter has a water separation efficiency of over 98%, which can effectively reduce engine cylinder wear, fuel injector blockage and other faults, and extend the equipment overhaul cycle.
In terms of quality control, all filters follow the original production standards of Wirtgen, from filter material selection, shell injection molding to sealing ring assembly. Each process is verified by a third-party testing agency to ensure that the dimensional tolerance is controlled within ± 0.1mm, and the sealing performance remains stable at extreme temperatures ranging from -35 ℃ to 130 ℃, avoiding equipment shutdown caused by fitting problems. As a supplier, Ningbo Qiuning Trading has established a strict warehousing quality inspection process, conducting filtration efficiency, pressure strength, and aging resistance tests on each batch of products to ensure that all delivered products are original and genuine.
For wholesale purchasing customers, Ningbo Qiuning Trading has launched multiple service advantages: firstly, it has a stock of over a thousand full series filters, which can meet customers' bulk purchasing needs of hundreds of items per order, avoiding construction delays caused by stock shortages; The second is to implement a tiered pricing policy, where the larger the purchase quantity, the lower the unit price.
