Ultrapoly? PE

Product catalog summary

Overview: The document discusses the Donaldson Ultrapoly™ PE filter elements, which are designed for the removal of solid contaminants in gases. These filters are suitable for use as prefilters or post-filters in various industries.

Specifications: The Ultrapoly™ PE elements are made from highly porous sinter polyethylene filter media, capable of removing fine dust particles and contaminants from compressed air and gases. The filters utilize mechanisms such as direct impaction and mechanical sieving to retain particles based on the element pore size.

Applications: These filters are ideal for industries including chemical, petrochemical, pharmaceutical, plastic, food, beverage, general machine fabrication, and instrumentation and control air.

Features and Benefits:

Filter surface ranges from 5.5 in² to 480 in², accommodating various applications and flow rates.
Porosity grade of +45% offers high dirt holding capacity and lower differential pressure.
Temperature range from -4°F to +176°F allows for broad application use.
Guaranteed retention of contaminants down to 25 μm.
Regenerative design for economical and longer service life.

Performance and Calculations: The document provides examples of pressure drop calculations for low and high flow scenarios, demonstrating how to convert flow rates from standard cubic feet per minute (scfm) to actual cubic feet per minute (acfm) and calculate pressure drops through the filter elements.

Materials: The filter media is made of pure high molecular polyethylene, with epoxy resin bonding and aluminum end caps. The filters include two Perbunan® O-rings, which are silicone-free and free of parting compounds.

Performance Curves: The document includes performance curves for the 1030 filter element, showing the relationship between volume flow and differential pressure.

Catalog excerpts

Particle Filter Element Element for the removal of solid contaminants in gases as a prefilter or post filter. Donaldson® Ultrapoly™ PE elements contain highly porous sinter polyethylene filter media. Even the finest dust particles and other contaminants in compressed air and gases are being removed effectively on the surface and in the depth of the filter medium. By utilizing various filtration mechanisms such as direct impaction and mechanical sieving, particles are retained 100% in gases related to the element pore size. Particle Filter Element The Donaldson Ultrapoly PE filter element is ideal in the following industries and applications: • General machine fabrication
