AP-FIL-04-10 - Walter Replacement Foam Pre-Filters 10-Pack

Industrial Grade Pre-Filtration

The Walter Foam Pre-Filter (10 Pack) is an essential consumable for maintaining the efficiency and longevity of your industrial fume extraction systems. Designed to act as the first line of defense in air purification, these foam filters effectively capture larger particulates, grinding dust, and potential sparks before they can reach and damage the more sensitive and expensive main filter cartridges.

In heavy-duty industrial environments, air quality control is paramount. By utilizing these pre-filters, facility managers can significantly reduce maintenance costs associated with premature main filter failure. The foam material is engineered to allow sufficient airflow while trapping coarse debris that would otherwise clog HEPA or fine-mesh filters rapidly. This ensures that your extraction units maintain optimal suction pressure for longer periods, keeping your facility compliant with air quality standards.

This product comes in a convenient pack of 10, making it an ideal stock item for maintenance departments. Regular replacement of pre-filters is a simple, cost-effective strategy to ensure your Walter fume extraction equipment operates at peak performance. Whether used in welding bays, grinding stations, or general fabrication areas, these filters provide the reliability required for continuous industrial operations.
