The small series of POLO vacuum filters. Can be used up to a maximum of 900 l/min emulsion. A high flow rate is reliably achieved in a small area due to the vacuum. High throughput and excellent filtration.
Vacuum filter / Suction belt filter
Vacuum filter, also known as a suction belt filter
The vacuum filter, also known as a suction belt filter, creates a negative pressure that draws the liquid to be filtered through the filter cake. By means of negative pressure, the specific area throughput is significantly increased compared to a gravity filter. The air that is drawn through the built-up filter cake enables a residual moisture of the filter cake down to below 20 per cent. This effect is enhanced by the exhaust air from the exhauster, which is directed onto the filter cake from above.
Advantages of vacuum filters / suction belt filter
- Small space required, relative to the high throughput rates
- Dry-proof cake discharge
- Perfect utilisation of the filter aid
- Low maintenance
- Long service life
- Low fleece usage
Areas of application of suction belt filters
Mainly for supplying machine groups or central systems
