We also can configure 250x100mesh with 0.006mm, 150x70mesh with 0.015mm, 70×30 with 0.03mm. These configuration won&#;t be described as API 200 or etc. before being tested or certified by API test center.

So different configuration will result different character or features. For example, the rectangular holes combination will provide better conductance. And the mixture configuration will provide both conductance and durable life. If we prefer or focus on only one feature we can inquire supplier or manufacturer for optimal solution
