Inclined bed filter SB
The special feature of the POLO inclined bed filter SB is the unique fleece guide. Unlike conventional models, the fleece is not pulled but carried. This anti-tear principle enables the use of extremely thin and thus low-cost fleeces.
This ensures maximum process reliability. The filter purifies many different liquids fully automatically.
Short info
- Compact filter
- 6 different sizes
- Low fleece usage
- Transport by chain
- Also available in different stainless steel qualities
Wide range of fleece
thus optimised adaptation to the operating conditions. Many factors such as filter fineness, flow rate or fleece required can be optimised through fleece selection. The transport chain also allows extremely thin fleeces to be used.
Less fleece required
POLO inclined bed filter SB works with an endless transport chain that carries the filter fleece in a way that is gentle on the material. An deep filter trough is formed, resulting in a high liquid level. Due to the high hydrostatic pressure, the liquid throughput and the fleece consumption are optimized. The filtering process is safe and efficient.
Design
The special design of the filter housing creates a deep filter trough. The fleece is carried through the filter bed by means of a chain. The use of lightweight fleeces is possible with no problems at all. A side seal ensures exact separation between the dirty and clean sides of the filter.
Function
The liquid is fed to the filter without pressure by means of the inlet distributor, flows through the fleece and, when cleaned, reaches a clean tank below through the outlet.
The shape of the filter bed allows a high liquid level. This increases the throughput and makes the best possible use of the fleece. The dirt particles are deposited on the fleece and reduce the flow more and more.
These dirt particles (filter cake) represent an additional, high-quality filter layer and thus improve the filter result. The level rises in the dirt side of the filter. When an adjustable liquid level is reached, the fleece pre-stroke is triggered.
The filtration process is not interrupted during the fleece pre-stroke, an additional buffer tank for the soiled liquid is not necessary!
The built-up filter cake is a valuable filter aid and significantly improves the degree of purity.
Due to the short fleece pre-stroke, only a very small part of the filter surface is renewed, so that the essential part of the built-up filter cake remains and thus increases the filter fineness.
A hose seal, resistant to all commercially available cooling lubricants, reliably isolates the dirt chamber from the clean side.
A fleece shortage switch signals that the fleece roll needs to be replaced.
