Custom-Built Self-Cleaning Filters

Custom-built Self-cleaning Filters

Custom design and build any viable size, shape and capacity self-cleaning inlet filter

All our self-cleaning inlet filters incorporate the same tried and tested continuous backwash system to keep the filter mesh clear.

By combining our award winning self-cleaning filter technology with sound engineering and modular design principles Rotorflush Filters Ltd. can design, manufacture and deliver custom-built self-cleaning filters. You can oder an industrial self cleaning water intake strainer to meet your particular project requirements.

Within reason we can scale our filters to meet particular flow rates and size them to fit difficult locations. We can do this by varying the diameter relative to the height of the filter, and by combining filters together to meet a given flow rate.

Size and Capacity

Our custom-built self-cleaning filters can be scaled to meet particular flow rates.  The capacity of the strainer is determined by diameter and height of the mesh area.

Our filters are specified on this basis, so an RF800-600R is a Rotorflush filter with a filter mesh 800mm in diameter and 600 mm high. Similarly an RF600-800R filter is a Rotorflush filter with a filter mesh 600mm in diameter and 800 mm high. These filters will have the same area, and the same intake capacity.

So we can vary both the shape and the size of our filters.

Custom Sized Filters and Strainers

The table below gives indicative flow rates by dimensions, diameter on the left column, height of mesh across the top.

Our large industrial strainers are designed for large volume low maintenance water abstraction and filtration. These self-cleaning basket strainers can reduce the capital costs of civil engineering works typically associated with water intake screening because the filter can be mounted on a pipe directly in to the water source.

These are self-cleaning coarse screened strainers with capacities from approximately 100 cubic meters per hour up to 1500 cubic metres per hour. The strainers are all stainless steel construction and the filter mesh sizes are 3mm and 6mm as standard. Filters with mesh sizes from 1 mm to 10mm can be provided.

The continuous automatic backwash ensures that debris is kept clear of the screen thus preventing blinding.

Other Filter Configurations

In addition to scaling our filters, existing designs can be combined to provide desired flowrates io fit particluar locations.

For example, our RF400 self cleaning filters have a capacity of 60 m³ per hour.  We have produced double sized RF400 filters to meet customers’ requirements for 120 m³ per hour in a shallow river, and for a narrow sump.

The RF400 Duplex is a custom built self-cleaning filter that comprises 2 self-cleaning filters sharing a singfle output, for use in water of a minimum depth of approx 375mm.

The RF400-400 filter provides the same capacity as two RF400 filters but can be used in a narrow 800mm diameter sump.

Rotorflush Custom-built Self-cleaning Filters and Strainers

Our strainers are designed for large volume, low maintenance abstraction and filtration in industrial settings. Our self-cleaning filters can be mounted on a pipe or pump directly into the water source. Our filters operate at wildlife friendly velocities and have a range of mesh sizes.

All our industrial water filters and strainers have a continuous automatic backwash that keeps debris clear of the filter screen. This prevents blinding and blockage of the strainer, pump and any other equipment down the line.

The strength and reliability of these automatic backwash filters makes them a popular and inexpensive choice when considering filtration on capital projects.
