High-Efficiency Whole House Filtration Without Chemical Regeneration

Unlike conventional downflow filters, the upflow configuration improves media contact time and efficiency, making it ideal for a variety of filtration applications including carbon filtration, specialty media, sediment reduction, and taste improvement.

If you are looking for a versatile, economical whole-house filtration solution without chemical regeneration, the CLU Series delivers dependable performance.

What Is an Upflow Filtration System?

Traditional filters use a downflow configuration, where water enters from the top and flows downward through media.

An upflow system reverses this process:

• Water enters from the bottom.
• It travels upward through the media bed.
• This increases contact time.
• It reduces channeling.
• It improves filtration efficiency.

The result is better media utilization and improved overall performance.

Available Models & Flow Rates

The CLU Series includes four primary models:

CLU9

• Media capacity: 1.0 cu ft
• Continuous flow rate: 4 GPM
• Intermittent flow rate: 6 GPM
• Tank size: 9 x 48

CLU10

• Media capacity: 1.5 cu ft
• Continuous flow rate: 5 GPM
• Intermittent flow rate: 7 GPM
• Tank size: 10 x 54

CLU12

• Media capacity: 2.0 cu ft
• Continuous flow rate: 6 GPM
• Intermittent flow rate: 8 GPM
• Tank size: 12 x 52

CLU13

• Media capacity: 2.5 cu ft
• Continuous flow rate: 8 GPM
• Intermittent flow rate: 10 GPM
• Tank size: 13 x 54

Model selection depends on household size, water demand, and media type.

Key Benefits of the Upflow Filter Series

1. Media Flexibility

You can customize the system with various media types depending on your water quality concerns, including:

• Granular Activated Carbon (GAC)
• Specialty iron media
• Sediment media
• Catalytic carbon
• Specialty adsorption blends

This flexibility allows targeted treatment instead of over-engineering your system.

2. Enpress Vortech Distributor Plate

The built-in Vortech mid-plate distributor improves:

• Backwash efficiency
• Media expansion
• Flow distribution
• Water conservation

The plate design helps prevent media solidification and bypassing.

3. No Chemical Regeneration Required

The system operates without:

• Salt
• Chemicals
• Brine discharge

It is an economical alternative in applications where softening is not required.

4. Bypass Included

Each unit includes a bypass assembly with 1″ MNPT connections, allowing easy servicing without shutting down water to the home.

5. Compact, Efficient Design

Space requirements are modest and vary by model, making these systems suitable for:

• Utility rooms
• Garages
• Basements
• Mechanical closets
