The deployment of BMP-1, BMP-2 IFVs, T-64A, T-64B and T-80 tanks with single-stage air filtration systems with an average purification rate of 99.8% confirmed their superiority over existing two-stage filter systems: lower weight, smaller dimensions and easier maintenance. While the given purification rate of 99.7-99,8%, achieved by the T-80's cyclone filter array, is substantial, it does not meet industry standards set by OST V 3-2627-75. OST V V-2627-75 is a Soviet and post-Soviet industry standard that dictates that AFV air filtration systems with cyclones have to meet necessary protection requirements against foreign debris that can get logged inside the cyclone cones, like pine needles, hay, dirt/mud, petroleum-based products, spent gas molecules, snow and others. This implies that the cyclones have to be protected by a mesh and or filter and can not be directly exposed to the environment. A blocked cyclone array can severely reduce the air supplied to...
