The figures below are the reference values for the standard build of this model. The actual configuration is adjusted to the oil, the throughput and the power supply on site; the technical agreement signed by both sides is what counts.

Fine filter element 150-500-5
Deep-layer fine filter element for the ZYD series, 1~5 μm accuracy, reaching NAS class 5 cleanliness.
01Applications
For the final filtration stage of the ZYD-100 two-stage vacuum oil purifier, supplied as a set of 5. Also available in other outer diameters for the corresponding stage of other models.
Insulating oil, transformer oil and other duties requiring 1~5 μm filtration accuracy.
Outer stainless steel mesh, inner imported HPM deep-layer filter medium
A double-layer structure of outer stainless steel mesh and inner imported HPM deep-layer medium captures contaminants through the depth and gives a high dirt holding capacity. The 1~5 μm accuracy corresponds to NAS 1638 class 5 cleanliness, and the over-pressure alarm of the equipment indicates when the element needs replacing.
02Overview
Deep-layer fine filter element for the ZYD series, 1~5 μm accuracy, reaching NAS class 5 cleanliness.
Each machine is designed and built to the company standard and goes through a no-load and a full-load run test before it leaves the works. The test record and the certificate of conformity travel with the machine. Yanneng can work out the right configuration and the treatment line from the oil analysis report and the site conditions you provide.
