Efficient System Design
Kadant's Posi-Brush showers are designed and built for applications using filtered-fresh water or recycled-process water. Especially effective in paper machine applications subject to high process water contamination, Posi-Brush showers provide reliability, easy maintenance and low operating cost.
The pipe I.D. and nozzles remain clog-free due to a simple, effective design. Full-length internal, stainless steel brush assemblies clean the full internal pipe circumference and the nozzle orifices that protrude inside the pipe. This comprehensive sweep prevents solids build-up, eliminates contamination problems and directs the loosened debris to the integral flush valve.
Applications
- Paper machine fabric and roll cleaning
- Filter press belt cleaning
- Extractor belt cleaning
- Replace existing fresh-water showers
Effective Manual or Automatic Cleaning
Removing contaminants from the nozzles and flow pipe is a simple process. The showers are supplied with standard manual cleaning or optional automated cleaning using the Auto-Brush Actuator.
Manual cleaning, using the standard supply ratchet wrench or optional hand-wheel, involves opening the flush valve and rotating the brushes 360° in both directions. The loosened contaminant flows through the flush valve and is disposed off-process without contaminating the paper machine or product. The brushes are returned to "park" position, the flush valve is closed, and the shower is ready to continue operating.
