Discover the edge gap filter, the optimal solution for the filtration of viscous media in industrial and food applications. These self-cleaning filter systems offer a sustainable alternative to conventional filter elements by completely avoiding the use of disposable filter media and thus significantly minimizing the consumption of resources.

Thanks to their robust and stable construction, edge gap filter systems are designed for continuous use. They are characterized by high differential pressure resistance and a maximum operating temperature of up to 200°C. With flow rates of up to 70 m³/h, they can handle almost all low- and high-viscosity liquids without any problems.

How does the wedge wire filter work?

Filtration in the edge gap filter takes place from the outside to the inside through the cylindrical gap tube, where the solids accumulate on the outside. A geared motor ensures that the can continuously rotates. The attached scraper removes the filter cake from the surface, eliminating the need to dispose of conventional filter cartridges.

The removed solids collect in the lower part of the filter and can be easily removed from the housing in three ways:

• Manually by opening a ball valve
• Automatically via a time-controlled valve or
• Using an electronic control system with differential pressure monitoring that controls a drain valve

The AS50 edge gap filter is specially designed for industrial applications. It saves you the otherwise frequent opening and cleaning of the filter housing. With a maximum flow rate of up to 3.5 m³/h, it offers a reliable and efficient solution for the filtration of viscous media.

The AS50 model consists of the following parts:

1. filter housing and head
2. cylindrical slotted tubular element or perforated plate element
3. scraper basket with wiper
4. geared motor

The filter element is conveniently removed from below, which makes handling easier.

In addition to the standard edge filter with motor, models with a hand crank are also available. You can also order the edge filter with ATEX and food approval from us.
