High precision air resistanceMade using micro process technology, compared to traditional sintering method and capillary column method, the micro porous air resistance has higher consistency, better repeatability, longer service life, smaller size, and is easy to install and replace. In addition, the micro porous two-way air resistance adopts high-power microscope and airflow detection, with high precision, strong consistency, and small external dimensions, which can save space. The micro porous flow limiting air resistance can be calculated using the CV value formula, making it easy to convert the relationship between flow rate and pressure.

Thanks to its excellent product performance, microporous two-way gas barriers are widely used in fields such as medical devices, analytical instruments, pneumatic regulators, and gas path resistance balance in pipelines or chromatography columns. They can also be paired with pressure control to achieve precise and constant flow rates.
