DP-30 PLEAT
Pleated Air Filter
Standard & High Capacity

For greater filtration at an economical price, the DP FILTERS DP-30 PLEAT combines the filtration characteristics of the FARR Pleat Series with the four piece white U-Frame construction of a common throwaway, and is designed for use where any 1", 2", 4" or 1/2" pleated or disposable filter is used. Has a coated beverage board frame and metal grid, if applicable, for filter media support.

Design and Construction

Filter Media
The filter media used in all filters is a high performance, non-woven, reinforced cotton/synthetic fabric, specially manufactured to meet rigid performance specifications.

Media is available with an ASHRAE 52.1-92 (atmospheric) efficiency of 25-30%*.

Media Support
The media support is an "expanded diamond" grid with 97% open area. The filter media is bonded to the media support to insure pleat stability throughout the life of the filter.

Pleat Design
The filter employs a "radial V" pleat design. This guarantees total usage of filter media, and maximum dust holding capacity. This gives the user a greatly extended service life for cost savings.

Enclosing Frame
The DP-30 PLEAT utilizes a four piece heavy-duty white beverage frame with a metal "bottlecap" grid where appicable for additional stability and securely glued in place.
