Pre / Coarse Filters

Product Overview:

•Available in water- and moisture-resistant cardboard frames for durability.
•Features very low initial pressure drop with superior dust capture.
•Requires minimal maintenance for cost-effective operation.
•Excellent primary filter that prevents dust buildup on HEPA filters, coils, fans, and ductwork in HVAC systems.
•Enhances energy efficiency via sustained low airflow resistance, lowering fan power use.
•Engineered for diverse applications and harsh environments.
•Available in lightweight box-style (no header) construction with water/moisture-resistant cardboard frames.
•Heavy-duty expanded metal support grid.
•Consistent media with controlled fibre size.
•Extremely low initial resistance paired with high arrestance and extended service life.
•Higher dirt-loading capacity compared to shallower filters (e.g., 25mm), reducing change out frequency and costs.
•Larger pleat depth (up to 50 / 100mm) maximizes effective filtration area for harsh environments and high-airflow applications.
