Product Description

PL50-20BB 50 Micron 20" Jumbo Pleated Sediment Filter

The PL50-20BB is the ultimate heavy-duty filtration solution for environments requiring extreme flow rates and coarse sediment removal. With a 20-inch extended length and 4.5-inch large-diameter (BB) profile, this filter delivers maximum surface area for long-lasting performance. Rated at 50 microns, it acts as the primary "roughing" filter for whole-house systems, borehole extraction, and commercial applications, effectively trapping sand, grit, and large-scale debris while ensuring a massive flow potential of up to 90 lpm. Its durable construction, including a reinforced polypropylene core and leak-proof vinyl end-caps, ensures it stands up to the most demanding water conditions.

Why Choose the 20" Jumbo (BB) Format?

  • Massive Throughput: Rated for flow rates up to 90 lpm, making it suitable for large commercial or residential systems where pressure maintenance is critical.

  • Superior Coarse Filtration: The 50-micron rating is engineered to remove the most substantial sediment loads, preventing downstream blockages and equipment damage.

  • Reduced Maintenance: The 20-inch length provides double the media volume of 10-inch filters, drastically extending service intervals.

  • Bypass-Free Integrity: Vinyl plastisol end-caps ensure all water is forced through the pleat pack, guaranteeing consistent, reliable results.

You should use this filter when your water source (like a new borehole or river) carries high levels of coarse sediment (sand/grit) and you need a high-volume flow (up to 90 lpm) for your entire building. It is the perfect first stage to protect pumps and expensive downstream filter stages.

Big Blue (Jumbo) filters offer significantly more surface area and lower flow resistance. In high-demand settings, a 20-inch Big Blue filter prevents the pressure drop that often occurs with smaller slimline filters, ensuring better performance in showers, taps, and industrial equipment.
