RELIABLE PERFORMANCE IN HARSH ENVIRONMENTS
The Unite external scraper series filters are fully automatic self-cleaning filtration systems designed for a wide variety of liquid process applications.
This filtration system utilizes a cylindrical, cleanable filter element. An integrated blade cleans the filter by scraping away intercepted contaminants from the element's surface. This scraper self-cleaning function eliminates the need for disposable filter cartridges, thus reducing maintenance costs, labor, and downtime associated with element replacement. Unite filters feature unique brass or stainless steel filter media composed of wedge-shaped wires. The wedge-shaped wires are wrapped around a cylindrical perforated metal core, creating a conical flow path during filtration.
Low energy consumption operation reduces energy consumption.
Automatic cleaning reduces system downtime and ensures continuous production.
The scraper cleaning method reduces filter element wear and extends its service life.
Suitable for various industries, including water treatment, chemical, and food and beverage.
Robust and durable design, adaptable to harsh working environments.
Simple operation reduces user difficulty.
The filter element is characterized by a thin, wedge-shaped metal strip spirally wound onto a perforated metal core. The spacing between each metal strip determines the micron rating of the filter element. This spacing is precisely controlled during the winding process by forming protrusions on the strip. The tapered flow path in the Unitech filter element prevents clogging. Particles that cannot pass through may detach or be scraped off the surface by a cleaning blade.
The filter provides superior surface filtration performance for a wide range of critical commercial and industrial applications. The unique wedge-shaped strip media provides precise filtration performance to capture contaminants while allowing smaller particles to pass through without clogging the filter element.
The high porosity of the media allows the filter to handle a wide range of fluids, from water to highly viscous liquids such as syrups and toothpaste.
The self-cleaning characteristics of the filter ensure constant filtration over long production cycles. There is no need to stop production midway to replace the filter element.
Fluid enters the filter and solid particles are captured by the filter element.
When preset pressure or time is reached, the system automatically initiates backwashing.
Removed particles are flushed out through the drain outlet.
Differential pressure is continuously monitored to detect filter contamination.
Clean fluid flows in reverse direction to remove trapped contaminants from the filter surface.
The system resumes normal filtration without interrupting operation.
