Deep-Pleat Separator HEPA Air Filter

Product Overview

The Deep-Pleat Separator HEPA Air Filter is designed for high-efficiency air purification in cleanrooms and critical environments, featuring a thickness greater than 150mm. Unlike mini-pleat HEPA filters, this filter utilizes corrugated paper or aluminum foil separators, which increase airflow capacity, enhance structural stability, and ensure uniform air distribution. The larger filter depth allows for higher airflow rates, making it ideal for high-demand HVAC systems in industries such as pharmaceuticals, microelectronics, semiconductors, coatings, and healthcare.

Key Features

✅ High Efficiency & High Airflow – Captures 99.99% of airborne particles down to 0.3µm while supporting larger airflow rates
✅ Thicker Design (≥150mm) – Increases dust-holding capacity and extends service life
✅ Paper or Aluminum Foil Separator – Paper separators are lightweight and economical, while aluminum separators provide higher heat resistance and durability
✅ Low Resistance – Optimized pleat spacing ensures minimal pressure drop and energy savings
✅ Customizable Sizes & Frame Materials – Available in various dimensions to meet specific system requirements
