Suitable for oxygen - Taking gas filters into a new dimension


The new gas filter LE6 from WITT with 3" connection is a real giant –ideal for oxygen and other gases. The unique filter fineness reliably removes mechanical impurities in pipelines. Downstream equipment is protected and process performance is improved, reducing maintenance costs and expensive downtime.

With an almost 12 inches diameter, nearly 3 feet height, and weighing almost 441 pounds, the size and weight of the new gas filter alone are impressive. The LE6 is also suitable for oxygen, meeting the stringent requirements of EIGA, AIGA and CGA.

Even with the highest gas purities, particles can always occur in a pipeline. These particles can have negative impacts on the downstream process, such as reducing the performance and service life of plant components, as well as requiring more maintenance interventions. By means of 15 µm bronze filter inserts, the LE6 reliably removes out such contamination. Optimal functionality and service life of downstream plant components is ensured, thereby reducing operating and maintenance costs.

Two additional specifications that make the LE6 stand out are its 580 psi maximum operating pressure and high volumetric flow. Comparable filters of this size can often only be used up to 232 psi, do not offer the same filter fineness, and do not meet the EIGA, AIGA and CGA requirements for oxygen.

Differential pressure monitoring is also available as an option. The LE6 has connections at the gas inlet and outlet for attaching pressure gauges or electrical differential pressure transmitters. These measurements can be used to indicate the degree of contamination, thus optimizing the timing of preventive and reactive maintenance activities.

The LE6 shows its full potential when combined with a WITT dome-loaded pressure regulator. The incomparable control accuracy of these regulators is streamlined by integrating the LE6 gas filter.

The new LE6 from WITT is easy to install and maintain. The extended flange connections and lifting lugs allow simple installation. The filter cartridges can be changed in-line.

With the latest filter technology, WITT has once again proven its innovation in comprehensive gas control solutions.
