Pleated Panel Filter 20x25x1 is a Dynabrade filter panel sized 20 inches wide by 25 inches long by 1 inch deep, so it matches setups that specify this exact filter footprint and thickness for dust collection performance. The filter is described as a pleated panel type, which presents more filtration surface area in the same 20 x 25 x 1 envelope, helping the sanding table maintain airflow while capturing sanding dust. It is identified for use with dry downdraft sanding tables, so it is intended for tables that pull dust downward into an integrated dust collection plenum instead of updraft systems. The filter is noted as suitable for heavy duty tables, which indicates it is specified for more demanding sanding environments where the table regularly handles sanding operations. This filter is classified under dust collectors and accessories, positioning it as a working filtration element in a dust collection system rather than a general-purpose panel.
The stated 20 inch width, 25 inch length, and 1 inch depth give clear dimensional targets when fitting this Dynabrade pleated panel filter into a downdraft sanding table. Because the filter is identified for use with dry downdraft sanding tables, it is designed to sit in the air path under the perforated surface where dust-laden air passes through the media. The pleated panel design within that 20 x 25 x 1 envelope allows the media to occupy the available space efficiently, so the filter can be mounted in the designated slot or frame without changing the table layout. Linking this panel to heavy duty tables ties the geometry of the filter to sanding stations that see ongoing dust loads, where a consistent 20 x 25 x 1 replacement helps keep the table functioning as specified.
This Dynabrade pleated panel filter is identified for use with dry downdraft sanding tables, so its primary role is in sanding stations that pull dust downward through the work surface during sanding operations. In this role, the 20 inch width and 25 inch length let the panel span the designed opening beneath the table, so air passing through the perforated top encounters the filter media across the full area. The 1 inch depth aligns with housings that expect a slim filter profile, which keeps the panel within the allotted vertical space in the dust collection compartment. Being specified as a filter for heavy duty tables ties it to sanding environments where the table is a central work platform, so this panel acts as part of the dust control system at that station.
The pleated panel construction of this 20 x 25 x 1 Dynabrade 64658 filter folds the media into repeated pleats within the fixed outer dimensions, which allows a greater media area to be exposed to air moving through the downdraft table. This increased media area supports the dust collection function of dry downdraft sanding tables by giving more surface for sanding dust to accumulate while operating within the same 20 inch by 25 inch footprint. The 1 inch depth supports installation in filter tracks or frames that were engineered for that thickness, so the panel can sit properly without altering the table structure. Because it is positioned as part of dust collectors and accessories and noted for heavy duty tables, the defined dimensions and pleated layout work together as a serviceable filtration component where sanding dust needs to be captured at the work surface level.
This Dynabrade 64658 pleated panel filter is for dry downdraft sanding tables, so it serves sanding stations that pull dust downward into a dust collection system during sanding.
The pleated panel filter has a footprint of 20 inches wide by 25 inches long, so it fits downdraft sanding tables designed around that 20 x 25 inch filter opening.
The filter panel is 1 inch deep, which suits downdraft sanding table housings or frames that are set up for 1 inch thick pleated filters in the dust collection path.
The pleated design folds more filter media into the 20 x 25 x 1 size, so sanding dust meets a larger media area while the filter still fits the same downdraft table opening.
This pleated panel filter is described as a filter for heavy duty tables, so it is intended to operate in more demanding downdraft sanding environments.
This pleated panel filter is classified under dust collectors and accessories, so it functions as a filtration element in the airflow of a downdraft sanding table.
This Dynabrade pleated panel filter, part number 64658, provides a defined 20 inch by 25 inch by 1 inch panel built for dry downdraft sanding tables and referenced for heavy duty tables. Those fixed dimensions and its pleated construction align it with sanding stations that rely on a 20 x 25 x 1 dust collection filter in regular use. When a downdraft sanding table is set up around that size and style of panel, this filter serves as a direct way to keep the filtration portion of the dust collection path matched to the table design.
