Gas Filters

This rigorous filtration system is known throughout industry as the service life assurance for turbo compressors, reducing the risk of leaks from forming.

Dry gas seals are used as shaft seals in turbo machines in the petrochemical industry. The sealing gas which is pressurised externally is continually adjusted to maintain a higher pressure than that of the process medium inside the machine.

This effectively seals the housing and shaft from the process gases (which are wet, contaminated with particles, toxic and often flammable) to prevent the process medium from leaking into the atmosphere.

Dry gas seals on turbo machines are very complex systems and extremely sensitive to contamination from solid particles, aerosols and condensates.

While the shaft is rotating, a tiny gap, just 3 μm wide, is formed at the seal ring, through which the seal gas flows.

To protect these seals, the seal gases must be filtered accordingly to ensure the seal has as long a service life as possible.
