The Model 4D is the smallest complete Plate and Frame Filter Press available today. It is the perfect tool for R&D, pilot, or small batch processing. The Diamond Series line offers one of the most revolutionary design innovations in the history of plate and frame filtration. By literally turning plate and frame filtration on its ear, ErtelAlsop has created a filter that provides complete drainage and venting while maintaining the superior internally ported design the company is famous for.

These filters are able to accept up to twenty (20) filter pads, and have excellent scale-up capabilities. The 4D has the same component flexibility as other models, accepts various thickness filter media, and is internally ported eliminating the need for gaskets as well as concerns about compatibility and cross-contamination.
