The “MACH” bar screen is a package of mechanical chain operated bar screen previously which is known as CHFF, CHFB & CHFFM. For over last two decades, The “MACH” which is front raked, front/back return bar screen, is the standard for the industry with proven reliability. The “MACH” provides protection for the processing equipment by removing oversize debris from the sewage. Chain operated cleaning rakes intermesh with the bar rack, and elevate collected debris to a discharge point where each rake is wiped off before descending on the return side of the unit.

The CLAW Bar Screen

The “CLAW” bar screen is a rack and pinion bar screen previously which is known as the “RPFF”. From over last many years The “CLAW” which is heavy duty, front clean, front return type travelling rake mechanism transported on climbing carriage, is the standard for the industry with proven quality and reliability.

The “CLAW” shall be design to operate in a damp, wet, corrosive atmosphere. The material of construction is depending upon customer requirements and environment operating condition. All parts of the equipment furnished herein shall be amply proportional for continuous operation. Adequate lubrication shall be Provided for bearings, and lubrication points shall be readily accessible.

The LOCK LINK Screen

The Fairfield “Lock Link” design uses similar components found in our catenary screen, such as a durable head mechanism, sturdy stainless steel frame and bar rack. Unlike our Catenary which uses a welded steel chain, the Lock Link uses solid stainless steel link bars. The link bars and cleaning rakes descend on the upstream side of the bar rack, when the bar link system reaches the bottom of their travel, they articulate in the opposite direction in a catenary loop without requiring a lower sprocket. During ascension the rakes engage the bar rack at the channel floor and link bars lock together forming a solid frame. The entire Lock Link system is driven by a head shaft mechanism similar to our catenary design, eliminating the use of submerged mechanical components.

The Perforated Fine Screen

The perforated fine screen works on same principle as that of stream guard. water flows through perforated L shaped panels while debris are captured on the face of the element. the L shaped panels form a continuous belt which transports the debris to the discharge point where they are cleaned from panels by brushes and spray jet (optional). The debris is then discharged.

The Traveling Water Screen

A Traveling water screen from Fairfield is a cost efficient and customizable water debris removal system. There is no enhanced way to remove water debris than a traveling water screen.

Fairfield’s Traveling water screen is used to remove debris from the river or lake water, unlike bar racks and many other intake protection systems, which require costly monitoring and maintenance to keep free from blockages.

Screens are installed vertically in a concrete channel where debris clings to the upstream side of the ascending screen panels and is removed by water spray before the return run of screen panels descends on the down side of the screen.

Panels usually have square clear opening and fabricated of galvanized steel wire attached to steel angle frames by means of steel clamp bars and galvanized steel bars. Screen panels can also be fabricated of stainless steel wire.

Adjustable stealing strips will be used at basket ends on the vertical flights. No other clearance space in the boot or elsewhere which will constitute a water passage, whether between moving parts or between moving and stationary parts.

Water spray assembly with multiple nozzles is furnished to spray the full width of the screen panels and wash debris from the screen into a discharge trough. An electric solenoid- operated valve is furnished to actuate the water spray system when the screen machinery is operating.

TEKLEEN® water filters are the industry’s highest quality automatic, self-cleaning water filters and strainers. Specializing in providing industrial water filters and irrigation filters, Automatic Filters Inc. has created the leading water filter brand catering to some of the world’s largest customers.

A TEKLEEN® water filter will save you time and money that would otherwise be spent cleaning and replacing cartridges, bags, screens, & spray nozzles. Rinsing lasts only 4-15 seconds and uses less than 4-30 gallons of water without interrupting the main flow. We offer SST filters at carbon steel prices.


ABW Series
Automatic Back-Wash (ABW) Series filters are available in a wide range of industrial configurations. The filters can be custom manufactured to meet a wide range of industrial applications such as: ASME coded, sea water, high temperature, high pressure, and much more.

MTF Series
TEKLEEN® Minitwist series are low-flow, fully automatic, self-cleaning water filtration systems. These filters can handle flow rates from 1-600 gpm with screens as small as 10µ. The MTF filters use very little water for rinsing so the main flow is not interrupted. MTF Series are rated to 150 psi and 210°F.
LPF Series
The Low Pressure Filter (LPF) series is an all new line of fully automatic, self-cleaning water filters with working pressure as low as 15 psi and as high as 150 psi.
OBF Series
Automatic self-cleaning water filters in stainless steel — at the same low price of carbon steel. OBF Series filters are maintenance free and range from 2” to 12” and offer filtration down to 10µ.
CSB Series
Course Screen Brush filters are designed to filter contaminates such as algae, clams, zebra mussels, fish, and leaves from open water sources.
CSF Series
The Coarse Screen Flush filter series was specially designed for applications that don’t require fine filtration. Filters are automatic and self-cleaning, activated by a blow off that opens by differential pressure, timer, or manually for a very short duration.
Skid Series
Filter Skids are the compact and immediate, turnkey solution for many filtration needs. The skids are easily transported by a fork lift to any mounting locations. Light in weight and small in size, they offer a wide flow from 10-1,300 gpm and a filtration range from 10µ – 2,000µ in high quality SST construction at competitive prices.


Kusters Water

In addition to our standard products, Kusters Water has the ability to offer specialty built components to meet the project requirements.


> Centerless spiral screw type conveyors – all sizes
> Centerless load out conveyors – all sizes and configurations
> Horizontal, Inclined and Vertical
Dewatering Spiral
> As above with perforated trough dewatering section


Kusters Water offers a complete line of factory built static screens. Every screen is designed to provide trouble free liquid separation. The open screen design accommodates peak hydraulic flows and the deep influent head box reduces influent turbulence while delivering an even flow over the weir crest. A pivoting flow control baffle plate is provided to enhance even flow distribution and promote faster fluid removal by directing the fluid into the screen.
