ULTRAC A

Product catalog summary

Applications
Ultrac A adsorption filters are suitable for industries such as chemical, petrochemical, pharmaceutical, beverage, food, and more. They are used for prefiltration of sterile air, in filling and packaging machines, and for breathing air supply.

Filter Design and Functionality
The Ultrac A filter elements feature a two-stage filtration process. The first stage uses activated carbon to adsorb oil, hydrocarbons, and odors. The second stage employs binder-free borosilicate depth media supported by microfiber polyamide fleece to remove particulate contamination. An outer stainless steel core provides protection against pressure shock. The flow direction is optimized to minimize pressure drop and ensure full media utilization.

Features and Benefits

Optimized flow distributor reduces flow resistance and pressure drop, leading to energy savings.
Activated carbon granules are embedded in support foam to prevent abrasion.
High-density packing of activated carbon enhances adsorption capacity and efficiency.
Microfiber polyamide fleece improves particle retention, achieving ISO Class 2 quality.

Adsorption Effectiveness
The filter is highly effective against oil vapor, benzene, toluene, acetic acid, isopropyl ether, sulfuric acid, and citrus fruits. It shows good effectiveness against methanol, acetone, methyl acetate, and chlorine, but poor effectiveness against hydrogen sulphide, freon, and ammonia.

FILTRATION SOLUTIONS ACTIVATED CARBON VAPOR FILTER ELEMENTS Compressed Air & Process Filtration Adsorption filter for the removal of oil, hydrocarbons, Donaldson Ultrac A adsorption filter elements incorporate two stages of filtration. The first stage contains activated carbon for removal of oil, hydrocarbon and odor vapors through adsorption. The second filtration stage consists of binder-free borosilicate depth media, supported by microfiber polyamide fleece, for removal of particulate contamination in the air or gas stream. These filtration stages are followed and supported by an outer stainless steel core, which also protects the element against pressure shock. Flow distribution into and through the element has been optimized by the use of a carefully designed inlet/ outlet end cap incorporated into the element itself. Flow direction through the element is inside-to-outside, which minimizes pressure drop and assures full utilization of both layers of filter media. Residual oil content is less than 0.003 ppm with an inlet challenge of 0.01 ppm (might require recommended prefiltration). Activated Carbon Vapor Filter Element Adsorption Filter Design Particle filter Ultrac A adsorption filters are ideal in the following • Filling machines • Packaging machines • Food industry
