Watts Big-Bubba Depth Cartridge | BBC-150-D50 | AMPAC USA

The Watts Big-Bubba Depth Cartridge, model BBC-150-D50, offered by AMPAC USA, is a high-capacity, melt-blown polypropylene sediment filter engineered for Big Blue 4.5-inch x 20-inch filter housings. It removes suspended solids and particulate matter from water, protecting downstream filtration stages and delivering cleaner water for a range of applications. The "D50" designation reflects a 50-micron nominal rating — the cartridge captures particles 50 microns and larger, making it well suited as an initial filtration stage for heavily contaminated water sources.

• 50-micron nominal rating for first-stage pre-filtration of heavily contaminated water
• Melt-blown polypropylene media with graded density for high particle retention
• Fits Big Blue 4.5" x 20" filter housings, including Big Bubba Hydrosafe housings
• Double O-ring seals prevent bypass
• Jumbo format provides substantial dirt-holding capacity for longer service intervals

This cartridge excels where water sources carry high turbidity and significant suspended solids, serving as an ideal first stage in multi-stage Big Blue pre-filtration systems. Such systems commonly treat challenging sources like well water, surface water, or process water laden with sediment, rust, sand, and other particulates. By capturing these larger particles early, the BBC-150-D50 extends the lifespan and efficiency of finer downstream filtration stages, reducing overall maintenance and operating costs. Its jumbo format provides substantial dirt-holding capacity, supporting longer service intervals even in high-flow, high-sediment conditions.

Double O-ring seals ensure a secure, leak-free fit within compatible housings, including all Big Bubba Hydrosafe filter housings, preventing bypass so all water passes through the filter media. The melt-blown polypropylene media has a graded-density structure that maximizes particle retention throughout the filter's depth rather than just at the surface, giving it higher dirt-holding capacity than comparable surface filters and contributing to its extended service life.

AMPAC USA manufactures each BBC-150-D50 cartridge to stringent quality control standards using high-grade materials, delivering consistent, dependable filtration and long-term durability in demanding operating environments.

For pre-filtering water with heavy suspended solids, the BBC-150-D50 is an efficient, cost-effective choice. Its high capacity, 50-micron rating, and robust construction make it a valuable component for protecting and enhancing the performance of larger water treatment systems in residential, commercial, or industrial settings.
