Introduction
The Lees-Stop Filter by Velo Acciai S.r.l. offers an advanced solution for liquid processing, specifically designed to replace traditional rotary drum vacuum filters. It provides automatic filtration without the need for diatomaceous earth, resulting in a clean and brilliant wine (<1 NTU) that can be directly added to previously filtered batches without further treatment.

Specifications
The filter is equipped with stainless steel membranes designed for high durability and resistance to pressure, temperature, and chemicals. These membranes are particularly effective for filtering tank bottoms and other clogging products. The system can be configured with 2 to 8 membranes, each with a filtration surface of 7.5 m².

Filtration Process
The Lees-Stop Filter ensures consistent removal of solids, allowing for longer and more productive filtration cycles compared to traditional methods. The process is fully automatic, requiring minimal supervision, and the residues containing alcohol can be utilized in distilleries.

Performance
The filter offers higher recovery rates and maintains the quality of the wine, achieving a pre-bottling standard. It is available in various configurations, with flow rates ranging from 5-48 hl/h and daily volumes from 100-960 hl/day, depending on the number of membranes used.

Technical Data
The nominal technical data for different configurations (TLS 2 to TLS 8) include filtration surfaces from 15 to 60 m², flow rates from 5-48 hl/h, daily volumes from 100-960 hl/day, and yearly volumes from approximately 60,000 to 240,000 hl/year.
