Powerful first-stage protection with the Hydra BIG
The Atlas Filtri Hydra BIG self-cleaning filter uses a 90-micron stainless steel mesh to capture coarse sediment, including sand, rust, silt, and algae before it enters your water system. Engineered for high-sediment environments, it provides robust pre-filtration without reducing flow—making it ideal for agriculture, commercial systems, or tank-fed rural homes. As a first line of defence, it protects pumps, appliances, and downstream filters from clogging and wear.

High-flow brass connections for secure, reliable installation
The 1.5” BSP brass threaded ports are designed for maximum flow and leak-resistant installation in large-volume water systems. These solid brass fittings offer greater durability than plastic alternatives, particularly in high-pressure environments or systems subjected to frequent use. Compatible with standard NZ plumbing, they provide a secure, corrosion-resistant connection ideal for agriculture, commercial irrigation, stock water, and industrial filtration setups.
Whether you’re retrofitting an existing line or building a new system, these heavy-duty ports ensure hassle-free performance and long-term reliability.
Durable self-cleaning design with manual backflush
Built for high-flow performance and minimal maintenance, the Atlas Hydra BIG features a manual backwash valve that flushes trapped sediment—no cartridge changes, no disassembly required. Its 90-micron stainless mesh handles high sediment loads while maintaining pressure, making it ideal for irrigation, tank-fed systems, and commercial setups. With a flow rate of up to 250 L/min, it’s designed to keep your system clean and efficient for years with just occasional flushing.
HYDRA BIG - The ideal water filter for rainwater tanks, bores & surface water
This filter is designed for non-mains water sources: rainwater tanks, bore, and surface catchments. These supplies often carry sediment, debris, and organic matter—especially after heavy rain/ extended dry periods. Algae, runoff in creeks, dust, and droppings on roofs can all change water quality quickly. This coarse sediment filter captures it all at the point of entry, helping protect pumps, appliances, downstream filters while keeping your water clearer and more reliable.
Versatile high-flow filter for rural, agricultural & commercial water systems
The Hydra BIG is designed for high-sediment water sources: tanks, boreholes, creeks, and untreated surface water. With a flow capacity of up to 250 L/min, it’s ideal for farms, commercial workshops, livestock systems, and rural homes where water quality varies. Installed as a first-stage filter, it removes coarse sediment that would otherwise clog pumps, UV units, or irrigation lines—delivering clean, high-pressure water with minimal maintenance in demanding environments.
Steve's Pros & Cons
Pros of the Atlas Filtri Hydra Big self-cleaning filter
Effective first-stage filtration for sediment-heavy water: Self-cleaning water filter NZ
If you’ve got a lot of sediment in your water — stuff like sand, grit, or flakes from your tank — the Hydra BIG self-cleaning filter is a great way to catch it early, before it clogs up your finer filters or mucks up your UV system. It’s an excellent first line of defence and saves a lot of hassle down the line.
High flow water filter system : Convenient self cleaning design saves time and effort
One of the best features is the self-cleaning function. You don’t need to pull the whole thing apart to clean it. Just open the flush valve and let the system clear itself out. It’s quick, easy, and saves you time, especially if you frequently deal with dirty water.
Cons of the Atlas Filtri Hydra Big self-cleaning filter
Designed for large debris, not for fine filtration: water filter for rainwater tanks
The 90 micron screen is on the coarse side — it won’t grab the fine stuff. But that’s not what it’s designed for. It’s designed to remove the larger particles and allow your next filter stage to handle the finer ones. So, as long as it’s part of a multi-stage system, it works well.
Atlas Filtri Hydra big self-cleaning filter : Routine flushing is required
You do need to flush it regularly to keep things running smoothly. It’s not hard to do, but if you don’t stay on top of it, the build-up can slow your flow. The good news is that you can set it up to flush automatically with a timer, which essentially means it takes care of itself.
