20-Inch BB Opaque Pre-Filter Housing

Professional Grade 20″ Big Blue (BB) High-Capacity Housing

The 20-Inch Big Blue (BB) Opaque Housing is the ultimate water treatment solution for large Sri Lankan households, apartments, and businesses. With double the filtration surface area of 10-inch models, it ensures your entire property receives purified water at high flow rates without straining your pump or plumbing.

Key Features & Benefits:

• Algae-Proof Opaque Sump: The solid blue design is specifically engineered to block UV rays, preventing the growth of algae and bacteria inside the unit—a critical feature for Sri Lanka’s tropical climate.

• High Volume Performance: Supports flow rates of up to 35–50 GPM (gallons per minute), making it suitable for large residences (4+ occupants), hotels, and small industrial facilities.

• Heavy-Duty Construction: Built from thick-walled, reinforced polypropylene, this housing is exceptionally durable and resistant to a wide range of chemicals and high-pressure surges up to 125 PSI.

• Leak-Proof Reliability: Utilizes a dual O-ring seal (on select models) or a heavy-duty single O-ring to provide an enhanced, watertight fit even under continuous use.

• Simplified Maintenance: The integrated red pressure release button allows you to bleed air from the system, making it easy to unscrew the heavy sump during cartridge changes.

Typical Applications in Sri Lanka:

• Main Line Filtration: Installed at the point of entry to protect all internal plumbing from sand, mud, and rust.

• Semi-Commercial Use: Ideal for restaurants, car washes, and farms requiring consistent high-flow water.

• RO Pre-Treatment: Serves as a primary pre-filter for commercial Reverse Osmosis systems to significantly extend membrane life.
