Custom Fiberglass Dust Collect Filter Cartridge 175x185

The custom fiberglass dust collector filter cartridge 175×185 is a high‑performance pleated filtration element engineered for industrial dust collection systems operating in high‑temperature, corrosive, or chemically aggressive environments. 

The glass fiber media is precision‑pleated in an accordion configuration around a perforated steel or expanded metal core, maximizing effective filtration area within the compact envelope. The wide‑pleat design ensures high airflow while maintaining low pressure drop, and the pleated structure can be designed with specialized configurations such as hot melt bead separation to maintain pleat spacing and optimize dust release during pulse cleaning.

* Exceptional High‑Temperature Resistance : Glass fiber maintains its physical and chemical properties at elevated temperatures, with continuous operation up to 260‑280°C (standard fiberglass), 350°C instantaneous, and some specialty grades up to 500‑900°C. Does not age, deform, or degrade under high‑temperature exposure.

* High Filtration Efficiency : Ultra‑fine glass fiber media captures particles down to 0.3‑0.5 μm with filtration efficiency ≥99.9% , and some configurations achieving up to 99.99% efficiency. Capable of meeting MERV 15‑16 and HEPA‑grade requirements.

* Excellent Chemical and Corrosion Resistance : Glass fiber resists a wide range of chemicals, acids, alkalis, and organic solvents, making it suitable for corrosive gas and chemical processing applications.

* High Strength and Structural Integrity : The high‑strength characteristics of glass fiber enable the filter element to withstand large airflow impacts and extend its service life. Precision‑pleated design maximizes filtration area within the compact envelope.

* Excellent Dirt‑Holding Capacity : The depth‑loading fiber structure (with up to 90% dust‑holding space) captures particles throughout the media thickness, providing extended service intervals and reduced maintenance frequency.

* Power Plants and Boilers : Captures fly ash, combustion particles, and hot fumes from coal‑fired and biomass power generation.

* Cement and Asphalt Plants : Filters fine cement dust, mineral fines, and hot exhaust gases from kilns and dryers.

* Metal and Foundry Industries : Captures airborne metal particles, hot fumes, and combustion byproducts from smelting, casting, and heat treatment operations.

* Waste Incineration Systems : Filters harmful particulates from flue gas, ensuring compliance with environmental regulations.

* Chemical and Petrochemical Processing : Filtration of corrosive gases, acid fumes, and chemically aggressive air streams.

* Welding and Laser/Plasma Cutting : Extracts welding fume and fine metallic particulates where high temperatures and spark loads are present.

* Gas Turbines and Compressors : Intake air filtration for gas turbines and compressors operating in dusty or high‑temperature environments.

* HVAC and Building Ventilation : High‑efficiency filtration for commercial and industrial HVAC systems requiring enhanced thermal and chemical resistance.

Q: Can this fiberglass air filter cartridge be cleaned and reused?
A: Fiberglass filter cartridges are generally disposable and designed for single‑use replacement when differential pressure reaches the change‑out point. While they support in‑service pulse‑jet cleaning, the media is not designed for washing or water‑cleaning – water will not remove embedded particles and may damage the fiber structure.

Q: Can this filter be used in wet or high‑humidity environments?
A: Yes. Glass fiber maintains structural integrity in high‑humidity environments and is compatible with high‑moisture air streams. However, excessive liquid water should be removed upstream to prevent premature pressure drop increase. For continuous high‑moisture applications with liquid water present, consider PTFE membrane‑coated alternatives.

Q: What is the difference between fiberglass and polyester filter media?
A: Fiberglass offers superior high‑temperature resistance (up to 260‑500°C), better chemical resistance, and higher filtration efficiency (≥99.9% at 0.3‑0.5 μm). 
Polyester is more economical, offers good moisture resistance, and operates up to 135°C. Choose fiberglass for high‑temperature, corrosive, or high‑efficiency applications.
