QUAD & CUBE FILTERS

FEATURES: The Glasfloss line of polyester bag filters offers medium efficiency in a wide range of applications. The rigid, self-seal design of these filters helps prevent air bypass and allows the filters to operate under adverse conditions, especially where high humidity is present. The Glasfloss Quad 440 features a two-stage 100% non-woven polyester media for maximum efficiency and service life. The open fibers on the intake layer catch the larger particles allowing the finer particles to be caught by the dense outflow layer. The Glasfloss Quad 420 is less restrictive to airflow and performs well in moderate dust loading applications. Glasfloss Cube Filters feature the same two-stage polyester media found in the Quad 440 and are available in regular, internal supported and unitized construction. Glasfloss Quad & Cube Filters perform well in both variable and constant volume systems.

CONSTRUCTION:
Quads - Glasfloss Quad 440 and Quad 420 filters are made with 100% non-woven polyester media. Glasfloss Quad 440 features a special, twostage media and Quad 420 features a dual-textured fiber blend media. The individual, heat-sealed pockets are mechanically fastened to a heavy-duty, internal wire frame. A header option is also available.

Cubes - Glasfloss Cube Filters are made with a two-stage 100% non-woven polyester media. The seams of all Glasfloss Cubes are sewn together for maximum durability. The Internal Supported Cubes use a heavy-duty internal wire frame for added rigidity. The back panels of the Unitized Cubes are fastened in the center for better airflow and media utilization.
