This can sometimes be two to three times the high commission when the traffic.
In addition to the typical working conditions of the data (pre-charge pressure, airflow, temperature ...)
So that the correct choice of filters, meaningful gas also need to be analyzed
The more complex the sealing system, the more stringent the technology is.
Dry gas seals are used as shaft seals for turbines in the petrochemical industry.
高水平的操作可靠性由于正确的过滤器设计。
使轴封可靠运行几个多年的持续经营，不仅精心制作测量和控制技术的密封气流需要，
但zui重要的是，高效和正确尺寸的双面过滤器。
当轴旋转时，微小的间隙，仅仅3μm宽，形成在密封环处，密封气体流过。
为了保护这些密封，密封气体必须是相应地过滤以确保密封具有一样长的时间尽可能延长使用寿命。
High level of operational reliability due to the correct filter design.
So that the shaft seal reliable operation for several years of continuous operation, 
not only elaborate measurement and control technology to seal the air flow needs,
But most importantly, the efficient and correct size of the double-sided filter.
正是由于这个原因气体密封过滤器 - 正确尺寸根据PI 614-5 - 根据流量大小预计连续使用几年后。
这有时可以是两到三倍高调试时的流量。

除了典型工作条件的数据（预充压力，气流，温度...）
以便正确选择过滤器，有意义的气体还需要分析
密封系统越复杂，过滤越严格技术。
干气密封件用作涡轮机中的轴密封件机器在石油化工行业。
Gas filters and all the measurement techniques are integrated into the sealing gas panel,
Make sure that the shaft seal always runs pressure and flow conditions in a constant state.
Since the seal is also subjected to natural wear years, 
it is also unavoidable to increase the gas flow through the seal and through the filter.、
It is for this reason that the gas seal filter - 
the correct size according to PI 614-5 - is expected to be used continuously for several years based on the flow size.
