Our experienced staff is attentive to the needs of our clients and specializes in customizing one-of-a-kind filtration equipment that is optimized for their on-site operations.

We also carry out the various steps of our production work in-house, including the sheet metal processing of individual iron plates, welding, and assembly. Processing and welding require high levels of technical expertise and finesse. Our professional craftsmen have been producing oil filter machines for many years and are able to carefully mold materials into complex shapes by drawing on their expert welding techniques. We are committed to offering our clients high-quality products that are created with superior technical skills.

In- House Manufacturing


The welded and manufactured components are carefully assembled one by one to ensure that there are no defects. After assembly, we conduct in-process inspections and test runs to confirm that the product is safe and of the highest quality.


4In-house Packing and Delivery

Each product is carefully packed and secured before shipping to the client. We are also happy to accommodate specific packaging requests for international export.
