Ahlstrom's pre-pleated grades can save valuable time and maximize the efficiency of the laboratory filter system. Pleating improves the effective surface area increasing flow rate and loading capacity thus decreasing filtration time. Pleated circles are available in 12.5cm to 50cm diameters. Grade 513 has a medium rate filtering speed with particle retention of 6 µm.
