DP Trio Filter Housing – 10” BIG – 1.5” In/Out

Atlas Filtri DP Trio Filter Housing with Spanner & Bracket

A commercial-grade triple filter housing designed for whole-house water filtration systems requiring high flow rates and multi-stage filtration.

This DP Trio housing system combines three 10” BIG filter housings onto a single moulded head, simplifying installation while reducing plumbing complexity and potential leak points. It is designed for domestic, commercial, and industrial whole-house water treatment applications using standard 10” x 4.5” BIG cartridges.

What’s Included

• Triple 10” BIG filter housing assembly

• Integrated moulded Trio head

• Wall mounting bracket

• Housing spanner

• Drain ports

• Pressure gauge ports

• O-ring lubricant (Lubrikit)

How It Works (Simple Explanation)

This housing system is designed to hold three separate filter cartridges in series, allowing you to build a complete multi-stage whole-house filtration setup.

Each housing can be configured with different cartridges depending on your water quality goals.

Typical setups include:

Stage 1 – Sediment Filtration

The first housing is commonly used for coarse sediment filtration.

This helps remove:

• dirt,

• rust,

• sand,

• bark,

• and organic debris,

protecting downstream filters and plumbing from premature wear.

Stage 2 – Fine Sediment or Carbon Filtration

The second stage is often used for:

• finer sediment removal,

• chlorine reduction,

• or chemical filtration.

This stage helps improve:

• water clarity,

• taste,

• and odour.

Stage 3 – Specialty Filtration

The third housing allows for additional treatment such as:

• scale reduction,

• PFAS reduction,

• fluoride reduction,

• or advanced carbon filtration.

This modular design makes the system highly flexible depending on household water conditions.

Features

Triple Housing Moulded Head

Using a single moulded Trio head:

• simplifies installation,

• reduces plumbing labour,

• and minimises potential leak points compared to separate housings.

Pressure Gauge Ports

Integrated pressure gauge ports make it easier to monitor filter performance and determine when cartridges require replacement.

Drain Ports

Built-in drain ports allow housings to be drained before servicing, helping make cartridge replacement cleaner and easier.

BIG Housing Design

The 10” BIG format supports:

• higher flow rates,

• lower pressure loss,

• and greater dirt-holding capacity than standard slimline housings.

This makes it suitable for:

• whole-house filtration,

• larger homes,

• and commercial applications.
