Spiral Filter

SPIRAL FILTER

Spiral Filters are designed for the filtration of liquids with high solid content in industries such as Chemicals, Food, Adhesives, and more. The discharge of the filter cake whether dry or wet is made easy through the opening and tilting of the filter container, allowing convenient removal of the spring cartridge.

FILTER OPERATION

The liquid containing high solid content is either pumped or gravity-fed into the filter container. Inside the container, a spring cartridge comprises a spiral wrapped around a perforated central pipe and supported by studs. The spiral is covered with a filter cloth and is tied to the central hollow pipe at each turn to maximize the filtration surface area. During operation, the liquid mixture passes through the filter cloth; the solids are retained on the cloth, while the filtrate is collected and discharged through the perforated pipe outlet.

Spiral filters can typically be used with filter cloths ranging from 10 mesh to 200 mesh, depending on the application and the type of solids being filtered. Here's a general guideline:

Notes

Selection Depends On:

• Nature of solids (size, shape, abrasiveness)
• Viscosity of liquid
• Required clarity of filtrate
