Pleated filter Opakair HT

micro glass fiberairfor the food industry

Overview
A compact V-bank fine filter for supply or exhaust air systems that require very high airflow with low pressure drop. Designed for continuous operating temperatures above 70°C (maximum 120°C) such as dryers and high-temperature process lines in food & beverage and industrial applications. The modern galvanised steel frame with a V-shaped pleat pack delivers high removal capacity and structural stability while minimising pressure drop and weight.

Key features

• Lightest V-bank steel fine filter in its category
• Suitable for very high air velocities (up to 3.4 m/s)
• Strong, airtight galvanised steel frame
• Maximum continuous operating temperature: 120°C
• Ultra-low outgassing suitable for sensitive processes
• Available in box filter classes: M6 (ePM10 70%), F7 (ePM1 55%), F8 (ePM1 70%), F9 (ePM1 80%)
