Greenway GAUV-10S UV Lamp & 20" Jumbo Twin Filter Replacement Kit

Keep your Greenway GAUV-10S UV water treatment system maintained with a complete replacement lamp and filter kit designed for the UV Option 4 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.

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 filtration sequence:

20 Micron Pleated → 1 Micron Depth → UV Treatment

Genuine — Greenway GAUV-10S Replacement Kit

Choose the Genuine option for the genuine replacement lamp and filter configuration used with the Greenway GAUV-10S Option 4 Deluxe system.

What's Included

• 1 × Genuine Greenway GW_GUVL-10S 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-10S Replacement Kit

Choose the Aftermarket option for compatible replacement components that maintain the same 20" Jumbo size and micron configuration.

What's Included

• 1 × Compatible GW_GUVL-10S UV Replacement Lamp
• 1 × Aftermarket 20 Micron Pleated 20" Jumbo Filter
• 1 × Aftermarket 1 Micron Depth 20" Jumbo Filter

The aftermarket components are compatible replacements and are not genuine Greenway/Pentair components.

The aftermarket filters are identified by their size, filtration type and micron rating, rather than using the genuine 20BPF20 and 20BPX01 model numbers.

How It Works

The Greenway UV Option 4 Deluxe combines two stages of sediment prefiltration followed by 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 reaches the finer second filtration stage.

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 ahead of UV treatment.

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

Stage 3 — GAUV-10S UV Treatment

Following prefiltration, water passes through the existing Greenway GAUV-10S UV system for ultraviolet treatment.

Treatment Path

20 Micron Pleated Sediment → 1 Micron Depth Sediment → GAUV-10S UV Treatment

Designed for Surface-Drawn Water Systems

The Greenway UV Option 4 Deluxe is configured for surface-drawn water applications including:

• Creek water
• Spring water
• River water

The twin 20" Jumbo filters provide staged sediment filtration before the water enters the UV treatment unit.

Why Prefiltration Matters for UV Treatment

The two filter cartridges progressively filter incoming water before it reaches the UV stage:

20 Micron → 1 Micron → UV

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

Water then passes through the 1 micron depth filter for finer filtration immediately before UV treatment.

Both Genuine and Aftermarket kits maintain this same filtration sequence.

About the Greenway GAUV-10S Option 4 Deluxe

The genuine Greenway UV Option 4 Deluxe configuration uses:

• Greenway GAUV-10S 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 UV system and filter housings.

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-10S 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 20" Jumbo size and micron configuration:

• Compatible GW_GUVL-10S 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.

Key Specifications

Compatibility

This replacement kit is configured for:

Greenway GAUV-10S

UV Option 4 Deluxe / UV_OPT4-D

Twin 20" Jumbo Filter Configuration

without representing the aftermarket cartridges as genuine branded models.

Installation

1. Isolate the incoming water supply.
2. Switch off and isolate electrical power to the UV system.
3. Depressurise the filter housings.
4. Remove the existing filter cartridges.
5. Install the new 20 micron pleated 20" Jumbo cartridge in the first stage.

Take care when handling the UV lamp and quartz components during servicing.

Maintenance

UV Lamp: Replace every 12 months.

Filter cartridge service life will depend on:

• Incoming water quality
• Sediment loading
• Water consumption
• Frequency of use
• Seasonal changes in the surface water source

Surface-drawn water conditions can vary, so filter condition and water flow should be monitored and cartridges replaced as required.

The aftermarket kit uses compatible cartridges with the same required 20" Jumbo size, filtration type and micron configuration.

Do Genuine and Aftermarket use the same micron ratings?

Yes. Both configurations use:

20 Micron Pleated → 1 Micron Depth → UV

The difference is the brand/manufacturer of the replacement components.

Which filter goes first?

Install the 20 micron pleated filter first, followed by the 1 micron depth filter, before UV treatment.

What's the difference between Genuine and Aftermarket?

The Genuine option uses genuine branded replacement components.

The Aftermarket option uses compatible replacements matching the required size, filtration type and micron levels, but they are not represented as genuine branded products.

Is the aftermarket UV lamp a genuine Greenway lamp?

No. It is a compatible aftermarket replacement.

How often should I replace the UV lamp?

Replace the UV lamp every 12 months.

Why replace the UV lamp if it still glows?

A UV lamp can continue producing visible light even as its effective germicidal UV output declines. Scheduled annual replacement helps maintain effective UV treatment.

Is this kit suitable for creek, spring or river water?

Yes. This kit is configured as the replacement set for the Greenway UV Option 4 Deluxe, which is designed for surface-drawn creek, spring or river water.

Does this include the complete filtration system?
