Atlas Filtri RLH Big Polyester Cartridge 90 Micron (RA5001010)

The Atlas Filtri RLH Big 90 Micron Polyester Filter Cartridge (RA5001010) is a washable, reusable sediment filter cartridge designed specifically for the Atlas Filtri Hydra Big range of self-cleaning water filters.

Manufactured with a durable polypropylene frame and polyester filter mesh, this cartridge provides effective filtration of larger suspended particles, including sand, rust, grit, scale and other sediment commonly found in water supplies.

The 90 micron polyester mesh offers a large filtration surface area, allowing high water flow rates with minimal pressure loss. Its washable design enables trapped sediment to be removed through the Hydra Big filter's backwashing system, reducing maintenance requirements and extending cartridge life.

Key Features & Benefits

90 Micron Filtration: Removes coarse sediment, sand, rust and suspended particles.
Polyester Filter Mesh: Durable, corrosion-resistant filtration material.
Washable & Reusable: Designed for repeated cleaning through the filter's backwashing system.
High Flow Capacity: Suitable for flow rates up to 15,000 litres per hour.
Low Pressure Drop: Large filtration surface area helps maintain water flow.
Durable Construction: Reinforced polypropylene frame for reliable performance.
Easy Maintenance: Sediment can be flushed away without removing the cartridge from the housing.
Genuine Atlas Filtri Replacement: Designed specifically for the Hydra Big self-cleaning filter range.

Frequently Asked Questions

What is the RAH BIG 90 Micron cartridge used for?

The RAH BIG is a washable sediment filter cartridge designed to remove suspended solids and larger particles such as sand, grit, rust and debris from water. Its 90 micron filtration rating makes it particularly suitable for high-flow pre-filtration applications.

Which filter housings is the RAH BIG cartridge compatible with?

The RAH BIG cartridge is specifically designed for use with Atlas Filtri HYDRA BIG self-cleaning filter housings. It should not be confused with standard 10" or 20" replacement filter cartridges.

What does 90 micron filtration mean?

A 90 micron cartridge is designed to retain suspended particles approximately 90 microns and larger. It provides relatively coarse filtration, making it ideal as a first-stage filter to protect finer cartridges and downstream water treatment equipment.

Is the RAH BIG cartridge washable and reusable?

Yes. Unlike disposable sediment cartridges, the RAH BIG has a washable stainless steel filter mesh and is designed for repeated cleaning and reuse.

How is the RAH BIG cartridge cleaned?

When installed in a HYDRA BIG self-cleaning filter, accumulated sediment can be removed using the filter's counter-current washing function. Periodic cleaning helps maintain flow and minimise pressure loss across the filter.

What flow rate can the RAH BIG 90 Micron cartridge handle?

The RAH BIG 90 Micron cartridge has a maximum recommended flow rate of up to 15,000 litres per hour (250 LPM), making it suitable for applications where considerably higher flow rates are required than a conventional cartridge filter can normally provide.

Is there a minimum flow required for effective backwashing?

Yes. A minimum flow of approximately 2,000 litres per hour is recommended during counter-current washing to achieve effective cleaning of the cartridge.

What is the filter mesh made from?

The filtering mesh is manufactured from AISI 316 stainless steel, providing excellent durability and corrosion resistance. The stainless steel mesh is incorporated into a reinforced polypropylene structure.

How long does a RAH BIG cartridge last?

Under normal operating conditions, Atlas Filtri indicates an average cartridge lifespan of approximately 24–36 months. Actual service life will depend on water quality, sediment loading, operating conditions and how regularly the cartridge is cleaned.

Can it be used to protect other water treatment equipment?

Yes. Installing a RAH BIG upstream can help reduce sediment reaching equipment such as water softeners, carbon filters, UV systems, pumps and finer cartridge filters, potentially reducing maintenance and premature fouling.

Is the RAH BIG suitable for drinking water applications?

Yes. The RAH BIG cartridge is suitable for drinking water filtration when installed and operated within the manufacturer's specified conditions. It removes suspended particulate matter only and should not be relied upon to make microbiologically unsafe water safe to drink.

Does a 90 micron cartridge remove bacteria or dissolved contaminants?

No. A 90 micron cartridge is a mechanical sediment filter. It does not remove dissolved contaminants, hardness, salts or reliably disinfect water. Additional treatment such as finer filtration, activated carbon, reverse osmosis or UV disinfection may be required depending on the water quality and application.
