Greenway GAUV-15S UV Lamp & 20" Jumbo Twin 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 5 Deluxe twin 20" Jumbo filter configuration.

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

The Greenway UV Option 5 Deluxe is designed for dairy sheds and other high-flow water treatment applications, using the larger GAUV-15S UV system together with twin 20" Jumbo prefilters.

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, filter type and micron configuration without representing them as genuine branded cartridges.

Product Options

Both options maintain the same treatment sequence:

20 Micron Pleated → 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 5 Deluxe system.

What's Included

• 1 × Genuine Greenway GW_GUVL-15S UV Lamp
• 1 × Genuine 20BPF20 — 20 Micron Pleated 20" Jumbo Filter
• 1 × Genuine 20BPX01 — 1 Micron Depth 20" Jumbo Filter

This provides the UV lamp and both prefiltration stages together in one convenient replacement kit.

Aftermarket — Compatible Greenway GAUV-15S Replacement Kit

How It Works

The Greenway UV Option 5 Deluxe combines two stages of sediment prefiltration 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 water before it progresses to the finer second-stage filter.

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

Stage 2 — 1 Micron Depth Sediment Filtration

The second stage uses a 1 micron depth 20" Jumbo cartridge for finer sediment filtration before the water reaches the UV treatment stage.

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

Stage 3 — GAUV-15S UV Treatment

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

The GAUV-15S is the higher-flow UV unit used in the Option 5 Deluxe configuration.

Treatment Path

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

Designed for High-Flow Applications

The Greenway UV Option 5 Deluxe is configured for applications requiring greater water flow, including dairy sheds and other high-flow situations.

The complete system uses the larger GAUV-15S UV unit together with twin 20" Jumbo filter housings.

The genuine 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 5 Deluxe system, rather than the replacement lamp and filter kit itself.

Why Prefiltration Matters for UV Treatment

The twin-filter configuration progressively filters incoming water before it reaches the UV treatment stage.

The treatment sequence is:

20 Micron → 1 Micron → UV

The 20 micron pleated cartridge provides the initial sediment filtration stage.

Water then passes through the 1 micron depth cartridge for finer filtration before entering the GAUV-15S UV unit.

Both Genuine and Aftermarket kits maintain this same filtration sequence.

About the Greenway GAUV-15S Option 5 Deluxe

The Greenway UV Option 5 Deluxe configuration uses:

• Greenway GAUV-15S UV unit
• 2 × 20BWH 20" Jumbo filter housings
• 1 × 20BPF20
• 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.

GAUV-15S Replacement Lamp

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

Genuine Lamp

Greenway GW_GUVL-15S

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

Aftermarket Lamp

The Aftermarket kit includes a compatible lamp matching the required:

• 40W output
• 893mm length
• Standard 4-pin connection
• GAUV-15S compatibility

The aftermarket lamp is a compatible replacement and is not a genuine Greenway-manufactured lamp.

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 UV lamp according to the annual replacement schedule rather than waiting for the lamp to stop glowing.

Genuine vs Aftermarket

Both options provide the same basic replacement configuration:

1 × UV Lamp + 1 × 20 Micron Pleated Filter + 1 × 1 Micron Depth Filter

Choose Genuine If:

You want the genuine replacement components:

• Genuine Greenway GW_GUVL-15S UV Lamp
• Genuine 20BPF20 20 Micron Pleated Filter
• Genuine 20BPX01 1 Micron Depth Filter

Choose Aftermarket If:

You want compatible replacement components with the same required specifications:

• Compatible GW_GUVL-15S 40W UV Replacement Lamp
• Aftermarket 20 Micron Pleated 20" Jumbo Filter
• Aftermarket 1 Micron Depth 20" Jumbo Filter

The aftermarket cartridges match the required size, filter type and micron levels, but are not sold as genuine 20BPF20 or 20BPX01 cartridges.
