Herding® ALPHA Filter System

nnnn

Field-proven and effective filter system for a temperature

nnnn

range of 250° C bis 450° C _

nnnn

► Excellent chemical resistance

nnnn

Filter media made of organic fibres are mostly inapplicable for operating temperatures

nnnn

exceeding 250° C. The Herding® ALPHA-filter is a high temperature resistant barrier

nnnn

filter on the basis of a mineral matrix Depending on the application it can be used for

nnnn

temperature ranges of up to 450" C(-840° F). The ALPHA-filter has excellent chemical

nnnn

resistance even at higher temperatures.

nnnn

The cylmdrically shaped filter elements are coated on the outside with a fine filtering

nnnn

inorganic layer, m order to achieve surface filtration in hot gas filtration applications for

nnnn

very lowparticle sizes with a long lifetime at low pressure orops.

nnnn

► Compact and space-saving design

nnnn

The Herding® ALPHA filter elements (Cluster) are installed vertically in the filter

nnnn

housing. This allows a compact and space-saving design and greatly simplifies the

nnnn

installation.

nnnn

► Filter housing, gas-tight or as pressure vessel nottomview

nnnn

The filter housing can be designed as gas-tight version or as pressure vessel. The materials used

nnnn

depend on the application. The filter candles, which are arranged in clusters, are cleaned by an online

nnnn

jet-pulse system.
