DEPTH-CLEAR™ utility grade filter modules are designed to meet the critical needs of the power distribution and generation industries in the reconditioning of dielectric oil used in transformers and circuit breakers. DEPTH-CLEAR™ media is formulated from specially selected cellulose fibers and inorganic filter aids. The cellulose fibers are highly refined in the manufacturing process to provide increased surface area, resulting in a filter with increased filtration efficiency and greater contaminant holding capacity. Two different series and three different media grades are available.
The DEPTH-CLEAR™ U Series is designed for the removal of carbon particles and low levels of moisture that result from the break down of dielectric oil. Removal of these contaminants increases the dielectric strength and the service life of the oil.
DEPTH-CLEAR™ U Series is available in three different grades, NA300, NA600 and NA1000. The NA300 is designed to remove particles above 3.0 micron and offers the highest filtration efficiency. The NA300 is commonly used to remove the finely divided carbon particles found in circuit breakers. The more open NA600 and NA1000 are used on heat-degraded oils found in transformers. The NA1000 is the most open of the utility series and provides higher flow rates and lower pressure drops.
The SA Series is designed for the removal of both water and carbon particles. SA Series modules incorporate a layer of water removal media located between an upstream and downstream layer of U Series media. The module is designed to withstand a strong pressure increase when the media is saturated with water. SA Series DEPTH-CLEAR™ is available with the NA300, NA600 or NA1000 grade of U Series DEPTH-CLEAR™ media. All SA Series modules are packaged with a desiccant to prevent the absorption of moisture from the air prior to use.

DEPTH-CLEAR™ P Series depth filter modules are specifically formulated to meet the performance demands of biopharmaceutical
and biotech applications. The filter media utilize mechanical and electrokinetic adsorptive capture mechanisms to remove particles,
microorganisms, colloids, and pyrogen from critical process streams. Purolator, a leader in depth media development, has invested years of research and development to create a range of filter grades to meet stringent application requirements.
The DEPTH-CLEAR™ proprietary formulation process produces filter media with exceptionally high, effective filtration area that provides superior particle retention, high contaminant holding capacity, and long on-stream filter life. Manufacturing by means of an advanced, highly automated production process results in very consistent product quality and filtration performance. Purolator can provide technical assistance to validate the performance of DEPTH-CLEAR™ filters in new processes and applications.
DEPTH-CLEAR™ Pharmaceutical Grade (P Series) filter modules are manufactured to procedures described in a Drug Master File (DMF) on record at the National Center for Drugs and Biologics. The filter media is non-toxic in accordance with systemic injection
testing. A special low extractable (LE Series) grade is available for susceptible processes and high purity applications. The DEPTH-CLEAR™ P & LE grades have complete product control and traceability, as set forth in the Drug Master File.
