Popis: 1. A new method is described for choosing a protective layer in the manufacture of two-layer finepurification filters of high sludge capacity. 2. Using this method, the component parts were chosen of a two-layer material for the fine purification of an aviation hydraulic fluid. 3. A two-layer filter material giving a purification fineness of 5μ and having acceptable permeability was evolved. The operating life of the two-layer material substantially exceeds that of FNS-5 filter material, which secures the same purification fineness and is currently recommended for application in aviation hydraulic systems.
