Product Introduction

The metal frame (e.g., aluminum alloy, galvanized steel) of Gate Purification's Pleated Pre-Filter of Metal Frame withstands high-temperature environments (ranging from 80 °C to 350 °C) and strongly acidic or alkaline gases. It is suitable for demanding working conditions such as paint spray booths and chemical production. Metal frames offer high resistance to deformation, minimal aging over long-term use, and are ideal for industrial systems with high airflow and pressure. Some models feature aluminum alloy frames weighing only 0.4–0.6 kg, balancing strength with installation convenience.
