Fiberglass Fabrics are woven for fiber orientation, and each fabric features its own unique weight, strength, and fabric characteristics.
Surface finishes and chemical treatments that aid in the collection and release of the dust from the bags: PTFE Hydrophobic impregnated, PTFE Membrane
Ultrasonic welded seam for increased efficiency and reinforced mechanical strength
Our laboratories are equipped with sophisticated testing equipment used to analyze and evaluate all aspects of your process and application
Custom fabricated bag designs to meet the unique needs of your bag house installation
Fiberglass has excellent resistance to most acids, but is attacked by hydrofluoric acid
Not recommended where bases and salts such as chlorides, bromides, and cyanides are present
Poor flex abrasion qualities
High tensile strength
Dimensional stability
High heat resistance, good thermal conductivity, and fire resistance
Outstanding Electrical Properties
Unaffected by sunlight, fungus or bacteria.
Finishes limited, maximum temperature range.
Glass fabrics are lower in cost than many other fabrics for similar applications.
Requires a 20 vertical wire minimum support cage when used in tubular filter bag form
Usually used in high heat applications. Continuous operating temperature of 500oF (260oC)
