Pentek 150235 20-BB 1-1/2″ #20 Big Blue Filter Housing

This Pentek 150235 20-BB 1-1/2″ #20 Big Blue filter housing with pressure relief is suitable for high-glide and heavy sediment applications. The sump is made of reinforced polypropylene for strength and resistance to chemicals, and the cap is made of high-glide polypropylene (HFPP) for stiffness. The cap has 1.5″ female National Pipe Thread Taper (NPT) threaded input and output connections and a nitrile butadiene rubber (Buna-N) O-ring to verify a watertight seal. A pressure relief button on the inlet side of the cap releases pressure in the housing for changing filter cartridges. The housing can be utilized with a 20” x 4-1/2″ filter cartridge (sold one by one). It has an initial pressure drop of 1 pound per square inch (psi) at a glide rate of 20 gallons per minute (gpm), a maximum operating pressure of 90 psi, and a maximum operating temperature of 100 degrees F (37.8 degrees C). This filter housing meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is for use in more than a few high-glide applications, including residential drinking water filtration, food service, and irrigation, among others.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Water filters remove undesirable particles, chemicals, and microorganisms from water by way of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibers that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralization. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems normally consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum glide rate, and the amount of water that may be filtered before the filter should be replaced. Water filters are used in quite a lot of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.
