Greenway GAUV-15S UV Lamp & 20" Jumbo Triple Filter Replacement Kit

Keep your Greenway GAUV-15S UV water treatment system maintained with a complete replacement lamp and filter kit designed for the UV Option 6 Deluxe triple 20" Jumbo filter configuration.

This maintenance kit combines the replacement UV lamp, 20 micron pleated sediment cartridge, radial flow granular activated carbon cartridge and 1 micron depth sediment cartridge required for routine servicing of the system.

The Greenway UV Option 6 Deluxe is configured for surface-drawn water such as creek, spring or river water where colour is an issue, combining three stages of filtration with the higher-flow GAUV-15S UV system.

Choose between Genuine and Aftermarket options. The Genuine kit uses genuine replacement components, while the Aftermarket kit provides compatible replacements with the same 20" Jumbo size and filtration configuration without representing them as genuine branded cartridges.

Product Options

Both options maintain the same treatment sequence:

20 Micron Pleated → Radial Flow GAC → 1 Micron Depth → GAUV-15S UV Treatment

Genuine — Greenway GAUV-15S Replacement Kit

Choose the Genuine option for the genuine replacement lamp and filter configuration used with the Greenway GAUV-15S Option 6 Deluxe system.

How It Works

The Greenway UV Option 6 Deluxe combines three stages of filtration followed by high-flow UV treatment.

Stage 1 — 20 Micron Pleated Sediment Filtration

The first stage uses a 20 micron pleated 20" Jumbo cartridge.

This provides initial sediment filtration, capturing particulate matter from the incoming surface water before it progresses to the carbon treatment stage.

Genuine: 20BPF20
Aftermarket: Compatible 20 Micron Pleated 20" Jumbo Filter

Stage 2 — Radial Flow Granular Activated Carbon

The second stage uses a 20" Jumbo radial flow granular activated carbon (GAC) cartridge.

This provides the dedicated carbon treatment stage in the Option 6 Deluxe configuration.

Granular activated carbon provides treatment for taste, odour and colour-causing organic compounds, making this stage particularly useful for surface-drawn water where colour is an issue.

Genuine: 20BRFGAC
Aftermarket: Compatible Radial Flow GAC 20" Jumbo Filter

Stage 3 — 1 Micron Depth Sediment Filtration

The third filtration stage uses a 1 micron depth 20" Jumbo cartridge.

This provides finer particulate filtration before the water reaches the UV treatment system.

Genuine: 20BPX01
Aftermarket: Compatible 1 Micron Depth 20" Jumbo Filter

Stage 4 — GAUV-15S UV Treatment

Following all three filtration stages, water passes through the existing Greenway GAUV-15S UV system for ultraviolet treatment.

Treatment Path

20 Micron Pleated Sediment → Radial Flow GAC → 1 Micron Depth Sediment → GAUV-15S UV Treatment

Designed for Surface-Drawn Water Where Colour Is an Issue

The Greenway UV Option 6 Deluxe is configured for surface-drawn water applications including:

• Creek water
• Spring water
• River water
• Surface water where colour is an issue

The key difference in this configuration is the addition of the radial flow GAC carbon stage between the initial sediment filter and finer 1 micron filter.

This gives the system a comprehensive treatment sequence:

Sediment → Carbon → Fine Sediment → UV

About the Radial Flow Carbon Stage

The Genuine Option 6 Deluxe uses the 20BRFGAC radial flow granular activated carbon cartridge.

The radial flow design provides the benefits of granular activated carbon filtration while maintaining relatively low pressure drop for higher-flow applications.

The GAC stage provides treatment for:

• Taste
• Odour
• Colour-causing organic compounds

For the Aftermarket kit, a compatible 20" Jumbo radial flow GAC cartridge is supplied to maintain the same filtration function without representing it as the genuine 20BRFGAC cartridge.

Why Prefiltration Matters for UV Treatment

The Option 6 Deluxe progressively treats incoming surface water before it reaches the UV stage.

The treatment sequence is:

20 Micron → GAC → 1 Micron → UV

The 20 micron pleated cartridge provides initial sediment filtration.

The radial flow GAC cartridge provides the carbon treatment stage.

The 1 micron depth cartridge then provides finer sediment filtration before water enters the GAUV-15S UV system.

Both Genuine and Aftermarket kits maintain this same treatment sequence.

About the Greenway GAUV-15S Option 6 Deluxe

The Greenway UV Option 6 Deluxe configuration uses:

• Greenway GAUV-15S UV unit
• 3 × 20BWH 20" Jumbo filter housings
• 1 × 20BPF20
• 1 × 20BRFGAC
• 1 × 20BPX01
• Surge protector

This replacement kit replaces the primary lamp and filter service components while retaining your existing GAUV-15S UV system and filter housings.

High-Flow GAUV-15S Configuration

The Option 6 Deluxe uses the larger GAUV-15S UV unit.

The complete system is specified at:

Recommended Flow: 92 L/min @ 30 mJ/cm²
Peak Flow: 174 L/min @ 16 mJ/cm²

These figures describe the complete Greenway Option 6 Deluxe system rather than the replacement lamp and filter kit itself.

GAUV-15S Replacement Lamp

The GAUV-15S uses the GW_GUVL-15S replacement UV lamp.

Genuine Lamp

Greenway GW_GUVL-15S

• 40W
• 893mm long
• Standard 4-pin connection
• Designed for the GAUV-15S
• Replacement lamp for UV_OPT5-D to UV_OPT6-D

Aftermarket Lamp

The Aftermarket kit includes a compatible replacement lamp matching the required:

UV Lamp Replacement

The UV lamp should be replaced every 12 months as part of routine UV system maintenance.

A UV lamp can continue to produce visible light even as its effective germicidal UV output declines.

For this reason, replace the lamp according to the annual replacement schedule rather than waiting for it to stop glowing.
