Wine filter sheets 20×20 cm for plate filters

Filter sheets are supplied in packs of 25 pieces, each sheet measuring 20 × 20 cm.

They are made in Italy to the highest quality criteria and current regulatory standards. These depth filter sheets are engineered to optimise depth filtration performance, delivering substantial improvements over surface filtration.

Filter sheets are widely used in the food, chemical and pharmaceutical industries thanks to their excellent retention characteristics and filtration quality.

They are used for roughing, polishing and removing particles and microorganisms present in liquids.

This specific type of filter sheet for plate/pump filters (e.g., Rover) is designed for roughing wine. It is therefore particularly suitable for young or very cloudy wines, as it retains the larger suspended particles typically present right after fermentation.
