The 4S plate & frame filter is one of the most economical models ErtelAlsop manufactures. Sized for bench top mounting, these filters are able to accept up to twenty (20) filter pads, they are designed to work in a wide range of high efficiency, ultra-fine filtration applications, and have excellent scale-up capabilities.
As with all ErtelAlsop plate and frame filter presses, the Model 4S 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.
