​Kusters ProTechtor® 
​Multi-Rake Bar Screens


The Kusters Water Multi-Rake Bar Screen was developed to solve the most demanding problems associated with wastewater pre-treatment. Kusters Water improved the basic design of conventional bar screens to offer a unique product to meet the ever increasing process needs of end users. The Kusters Water Multi-Rake Bar Screen combines fine or coarse screening with high solids capture rates, robust construction, long life, and low O&M costs all in one screen. This combination ensures operation when you need it most.
Functional Principle
Wastewater flows through the tapered stainless steel bars while the non-biological solids, such as paper and plastics, are trapped on the screen face. The screenings are removed from the tapered bars by rake arms fixed between two heavy duty roller chains. These rake arms utilize laser cut teeth that precisely engage and clean the tapered bars to a depth of 10 mm. The screenings are conveyed from the bars over a dead plate, where they have sufficient time to drain, and are discharged at the top of the screen into a dumpster, conveyor or compactor. The Multi-Rake Bar Screen is designed to tightly seal to the walls of the channel to prevent any bypass from occurring and, due to the design of the lower frame, a recess in the floor of the channel is not required.

Amwell-Inc. Bar Screens
​
Amwell builds quality heavy duty front cleaned bar screens to your specifications in vertical or inclined designs in widths from 1.5 ft. to 7 ft. and depths to 30 ft in stainless steel or carbon steel construction. All models are powered by shaft mounted direct drives. Options include “pivot mounted design” for easy maintenance and more. Choose Amwell bar screens as your first line of defense.
​Key Benefits & Features

Protect your downstream equipment from hazardous debris with reliable Amwell bar screens. Choose from stainless or carbon steel construction with widths from 1 ft. to 7 ft. and depths to 30 ft. All units feature shaft mounted direct drives controlled by either timers or differential liquid level controllers. Pivoted designs allow the entire mechanism to pivot out of the channel for ease of maintenance. Front cleaned screens can be vertical or inclined at 75° or 84°.
Standard screen openings are 1/2" to 1 1/2". Screen rakes are driven by your choice of stainless steel, cast iron or polymer coated chain with metallic or non-metallic sprockets. All bar screens are fully assembled and thoroughly shop tested to insure trouble-free operation prior to shipment. Units can be fabricated in sections to allow installation in existing structures.
  • Shaft mounted direct drive eliminates drive chain and sprocket maintenance.
