PRE Filters are designed as the first stage of filtration in HVAC systems, Laminar Air Flows, Dispensing Booths, and other air particle control systems. They efficiently trap coarse particles and protect downstream filters, increasing the lifespan of the entire filtration system. At Raj Creation, we offer PRE Filters in both standard and customized sizes, engineered for durability and efficiency in demanding environments.
Constructed using robust casing materials like Aluminium, GI, or SS 304, our filters are available in both Box Type and Flange Type designs. These filters use high-quality synthetic media with HDPE net or non-woven material, ensuring effective removal of particles while maintaining stable airflow and low resistance.
