Pentek GDA-7505-20BB Sediment Filters

Gradient Density Filters

Pentek GDA-7505-20BB cartridges are manufactured in the USA from 100% pure polypropylene and are sized for use in 10" Big Blue filter housings. Pentek GDA-7505-20BB filters are designed for purity and will not impact taste, odor and color. Pentek Pentek GDA-7505-20BB cartridges also provide superior chemical resistance and are not prone to bacterial attack.

Two unique layers provide up to three times the dirt-holding capacity than pleated, string-wound and standard spun polypropylene cartridges provide. A larger outer pre-filter reduces the partial load to the inner post filter allowing the cartridge to operate at higher velocities and lower pressure drop. The effective filter depth is increased over 200% of string-wound and standard spun-polypropylene cartridges for extended life, performance and reliability.

The design and performance characteristics of the Pentek GDA-7505-20BB filter cartridges make them an excellent choice for all residential, rural, municipal, industrial, and commercial applications.

The micron rating for the Pentek GDA-7505-20BB is absolute.
