The Dollinger GP-198 coalescing filter is engineered to remove entrained oil, water mist, other liquids and solid particles efficiently from compressed air and other gas streams. When the Dollinger coalescing filter is used within its rated design conditions, an efficiency off 99.9% on 0.3 micron aerosols is achieved.
As standard, the Dollinger GP-198 filter housing is designed and constructed in accordance with the ASME VIII, Division I Pressure Vessel construction code. (Compliance with the following codes is also available: Korean, SELO, PED, TÜV, and GOST).
In addition, Dollinger can also provide full design services to other pressure vessel codes Canadian and European.
The standard GP-198 filter housing incorporates bottom service access. If required, Dollinger can also provide housings with top service access.
The standard materials of construction of the Dollinger GP-198 filter are carbon steel or stainless steel. Special requirements for low temperature applications can also be accommodated.
The Dollinger GP-198 coalescing filter incorporates a unique, highly efficient filter element in standard or premium construction.
The convolutes design provides a much larger surface area than conventional elements which results in low pressure drop, high efficiency, high dirt-holding capacity and extended service life.
The standard coalescing element consists of multiple layers of borosilicate glass media and a pre-filter layer, supported by screen both upstream and down and pleated for maximum extended surface area.
A premium coalescing element is also available for high temperature or corrosive applications.
