Washable Cartridge · 20″ Big Blue
The 20 Big Blue Collared Washable Cartridge is a mechanical pre-filter for large-diameter Big Blue housings that can be washed and reused once it is dirty. It holds back suspended solids such as sand, silt, rust and sediment, protecting the filters and equipment behind it.
01Problem & Solution
Problem
In water with a heavy load of sand, rust and silt, single-use cartridges fill quickly. Frequent replacement means both cost and maintenance effort; neglected, pressure falls and the flow weakens.
Solution
The 20 Big Blue Collared Washable Cartridge is removed, washed and refitted once it is dirty. By holding coarse dirt at the front, it extends the life of the spun, carbon and membrane stages behind it.
02Key Features
The 20 Big Blue Collared Washable Cartridge provides long-term pre-filtration on large-diameter lines.
It is cleaned by washing under water when it gets dirty; you do not have to buy a new one each time.
Suits large-diameter Big Blue housings; the large filter surface delivers high flow.
The collar seats it correctly inside the housing so water cannot bypass the cartridge.
The large filtration surface keeps pressure loss limited even at high flow.
By holding coarse sediment at the front, it extends the life of the spun, carbon and membrane stages.
Being reusable, it reduces consumable spend on lines with a heavy sediment load.
03Technical Specifications
| Feature | Value | What it does |
|---|---|---|
| Product Type | Washable Sediment Filter | The product family it belongs to. When buying a spare, the family alone is not enough; the size and model must match too. |
| Size | 20" Big Blue | The physical size. If a spare does not match this, it will not go into the housing. |
| Construction | Collared Cartridge | How the unit is put together. A compact cabinet takes little room; an open system makes servicing easier. |
| Filtration | Mechanical (Sediment / Sand / Rust) | How many stages the water passes through and what cleans it. |
| Where It Is Used | Building Inlet / Industrial Line | |
| Maintenance | Cleaned by Washing | The regular maintenance load. If filters are not changed on time, performance drops. |
04Applications
The 20 Big Blue Collared Washable Cartridge is used on large-diameter water lines carrying a sediment load.
05How It Works
The cartridge is placed in the 20″ Big Blue housing so that its collar seats correctly.
Water from the line passes through the cartridge’s filtration surface towards the centre.
Sand, silt, rust and suspended solids are held mechanically at the filtration surface.
Freed of coarse matter, the water reaches the carbon or treatment stages that follow far cleaner.
When it gets dirty the cartridge is removed, washed under water and placed back in the housing.
06Making the Right Choice
When choosing the 20 Big Blue Collared Washable Cartridge, consider the housing size, the flow rate and the contamination load.
This cartridge is for 20″ Big Blue housings; standard 10″ housings take a different size.
On high-flow lines such as a building inlet, the 20″ Big Blue size is the better fit.
Where the sand and sediment load is heavy, a washable cartridge markedly reduces consumable costs.
If chlorine and odour are to be removed a carbon stage is needed, and where there is hardness, a softening stage as well.
