FiltreteTM Air Filter Media Type G

Including G, GS, GSB and GCC

3M Filtrete Type G air filter media is an electret filter media that goes beyond
conventional mechanical capture mechanisms by also using permanent electrostatic charges to remove airborne particles. It is ideal for applications where high efficiency, low pressure drop and high loading are critical and space is at a premium.[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner width=”1/2″][vc_column_text]

Characteristics:

  • Longer life and lower costs because of open construction with high loading
  • More economical operation due to low pressure drop with high efficiency
  • Permanently charged fibers capture more sub-micron particles than conventional media
  • Large selection of basis weights and thickness
  • Multitude of framing options
[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text]Type G family of media features an open and uniform web. It is uniquely constructed of permanently charged engineered fibers. The charged fibers enable the media to capture particles throughout the depth of the filter, rather than only on the surface.
The combination of electrets and open construction provide a low pressure drop with superior efficiency. A lower pressure drop allows the construction of a system with a higher flow rate and more air changes per hour. An alternate choice may be the same airflow but a reduced blower speed and quieter, more energy efficient operation. The overall results, beyond the increase in efficiency, may include longer life, reduced costs and energy savings.[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_single_image image=”285″ img_size=”large” alignment=”center”][vc_single_image image=”286″ img_size=”large” alignment=”center”][vc_row_inner][vc_column_inner width=”1/2″][vc_column_text]

Applications:

 

Applications include room air purifiers, air conditioners, disc drives, vacuum cleaner exhaust filters, copy machines, printers, electronic equipment and cabin air filtration. This media can also be used in a variety of medical applications including anaesthetic gas/respiratory care, pulmonary
function/spirometry and incubator filters[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text]

Product Selection:

Type G media comes in a large variety of basis weights and constructions to meet all your filtration needs. Basis weights range from 30 to 300 grams per square meter. We can assist you in a custom design of the optimum filter for your application. The graphs at the end of this document provide a good starting point for selection of the best product for your application. Please contact Technical Service for complete information.[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row full_width=”stretch_row” equal_height=”yes” content_placement=”top” css=”.vc_custom_1512123905652{background-color: #f2f2f2 !important;}”][vc_column][vc_text_separator title=”Type G Constructions” add_icon=”true”][vc_single_image image=”287″ img_size=”large” alignment=”center”][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_column_text]

Efficiencies and Pressure Drops:

The plot below and the ones on the following pages show initial efficiencies
and pressure drops for common basis weights of the Type G media at stated flow rates. We can also provide information at the specific flow rate and efficiency needs of your application.[/vc_column_text][vc_single_image image=”288″ img_size=”medium”][/vc_column][vc_column width=”1/2″][vc_column_text]

Framing

Filter frames can range from no frame, to flexible or lightweight frames, to
rigid or heavy duty ones. Please see Filtration Products’ bulletin “Framing
Options” for more information. It can be used as a starting point for
understanding the various options available. Consult with Filtration
Products Technical Service for specific applications.

Temperature and Humidity Resistance:

Type G media resists degradation over time and is able to withstand extremes in temperature and humidity up to 160oF (70oC) and 100% relative
humidity.
Recommended Shelf Life: Two years from date of product manufacture when stored at room temperature conditions of 72oF (22oC) and 50% relative humidity.

Cleaning:

Filters should be replaced rather than cleaned. Filter replacement schedule is
determined by application requirements.[/vc_column_text][/vc_column][/vc_row][vc_row full_width=”stretch_row” equal_height=”yes” content_placement=”top” css=”.vc_custom_1512123905652{background-color: #f2f2f2 !important;}”][vc_column][vc_text_separator title=”Efficiency vs. Particle Size” add_icon=”true”][vc_single_image image=”293″ img_size=”full” alignment=”center”][vc_single_image image=”291″ img_size=”full” alignment=”center”][vc_single_image image=”292″ img_size=”full” alignment=”center”][/vc_column][/vc_row][vc_row full_width=”stretch_row” equal_height=”yes” content_placement=”top”][vc_column][vc_text_separator title=”Pressure Drop vs. Face Velocity” add_icon=”true”][vc_single_image image=”294″ img_size=”full” alignment=”center”][/vc_column][/vc_row]
