The Pentek 150111 is a heavy-duty 3/4" NPT filter housing specifically engineered to handle high-temperature applications up to 165°F (74°C), making it ideal for hot water filtration systems, industrial processes, and commercial applications where standard polypropylene housings would fail. Constructed from reinforced glass-filled polypropylene, this Pentek housing accepts standard 10" Big Blue-style filter cartridges and features a robust design with a maximum operating pressure of 90 psi. Unlike standard cold-water housings, the 150111 uses specialized high-temperature O-rings and materials that maintain structural integrity under sustained heat exposure.

The Pentek 150111 housing accommodates standard 10-inch x 4.5-inch Big Blue-size filter cartridges, giving you flexibility to choose the right filtration media for your application. For high-temperature use, pair it with Pentek high-temp compatible cartridges such as sediment filters (available in 1, 5, 20, and 50 micron ratings) or specialty cartridges rated for hot water service. Always verify that the replacement cartridge is rated for temperatures up to 165°F to match the housing's capabilities. Standard carbon block filters are generally not recommended for hot water applications in this housing.

Filter cartridge replacement in the Pentek 150111 housing typically ranges from every 3 to 6 months, depending on the cartridge type, water quality, flow rate, and usage. For high-temperature sediment applications, inspect the cartridge every 2-3 months and replace when you notice reduced flow or a pressure drop of 10-15 psi across the housing. The housing itself is designed for long-term use and does not require replacement with each cartridge change, though the O-ring should be lubricated with food-grade silicone grease at each cartridge swap to maintain a proper seal.

The Pentek 150111 High Temperature Filter Housing features 3/4" NPT inlet/outlet ports, accepts 10" x 4.5" Big Blue cartridges, and delivers flow rates up to 8 gallons per minute (GPM) depending on the cartridge installed. Its operating temperature range is 40°F to 165°F (4.4°C to 74°C), with a maximum working pressure of 90 psi at 70°F. The housing measures approximately 21.75" in height and 7.5" in diameter and includes a pressure relief button for safe cartridge changes. A housing wrench (sold separately) is recommended for proper installation and cartridge replacement.

The Pentek 150111 is manufactured from FDA-compliant, food-grade materials suitable for potable water applications. While the housing itself is built to industry standards for safe drinking water contact, NSF/ANSI 42 or 53 performance certifications for contaminant reduction depend on the specific cartridge installed inside. For certified contaminant reduction, pair the 150111 with NSF-certified Pentek cartridges that match your filtration needs. Always confirm that both the housing and cartridge are rated for your specific application, especially when used in commercial food service, medical, or residential hot water systems.
