BDLG ratchet type screen changers

Clean design, user friendly, excellent compactness: the technical evolution for manual screen changers.

Più di una naturale evoluzione del BDL, la linea BDLG si distingue per un design estremamente pulito – frutto di un’attenta progettazione – un’estrema facilità d’uso e un’eccellente compattezza. Disponibili con masse filtranti da Ø 30 a Ø 160 mm, rappresentano una scelta di grande qualità fra i dispostivi ad azionamento manuale.
Il movimento della piastra porta-filtri avviene attraverso una serie di ruote dentate, azionate da una semplice chiave a cricchetto reversibile che consente, grazie al sistema di ripresa, di ridurre al massimo gli ingombri di azionamento. Il favorevole rapporto di riduzione rende il movimento della piastra agevole e priva di sforzo, anche con masse filtranti consistenti.

Frequently Asked Questions

BD Plast is an Italian company founded in 1986, specialising in the design, manufacture and sale of filtration systems for plastic polymers. Its product range includes manual, hydraulic and continuous-flow filter changers, static filters, components for extrusion lines and accessories. With 40 years of experience, the company manages the entire process: from engineering to on-site installation.

The manual filter changer is the most cost-effective solution, suitable for standard production runs where a brief interruption to the process is acceptable. The hydraulic filter changer allows filter elements to be replaced whilst the plant is running, making it ideal for high production capacities. The continuous-flow filter changer, on the other hand, ensures a perfectly uninterrupted flow of polymer, eliminating waste and interruptions in the production cycle: it is the ideal choice for lines where process consistency is critical.

The Clean Changer is BD Plast’s patented innovation, designed specifically for the extrusion industry. It is a high-performance solution that meets the quality and continuity requirements of the most advanced production lines. For technical details and to assess its suitability for your process, please contact our sales or technical team.

The range is much broader. In addition to various types of filter changers, BD Plast manufactures adaptors, bends, necks, accessories, support trolleys and hydraulic power units. Each component is designed for maximum integration into extrusion lines, whether for cast film, blown film or coating lines.
