PLEATED FILTER CARTRIDGES
Siga filtration offers pleated filter cartridges in a wide range of materials, lengths, end caps and micron ratings for industrial and hygienic applications. All filter cartridges in our FINEPleat range have absolute ratings (membranes) and Beta rating of 5000 (non membranes), which means that our pleated cartridges will provide consistent and reliable removal of particles, bacteria and contaminants at the rated pore size. A hard outer cage protects the pleats from damage and provides support during cleaning and sanitisation.

All filter cartridges in our hygienic filtration range are manufactured from FDA approved components and suitable for food contact. FINEPleat membrane filter cartridges carry validated removal ratings.
