Metallic and Cleanable Filters

World Class Filtration Solutions

Candle Filters for the Polymer Melt Industry

Porvair Filtration Group's candle filters are available in both cylindrical and pleated formats, in industry standard designs, or can be custom designed to fit any particular housing. These are available in both sintered metal fibre and woven wire mesh.

Available in filtration ratings from 3 to 100 microns, our candle filters are normally supplied with an outer guard, both to protect the media and to allow reverse flow during cleaning. Our candles are readily cleanable with current technology.

All candles are provided with internal volume reduces to avoid stagnant flow regions within the candle design. Flow diverter features within the volume reducer provide good distribution over the candles as the polymer enters the housing.

Using our range of high strength, highly permeable stainless steel fibre media, results in candle filters with low initial pressure drops and long on-stream life.
