The rotary drum filter is a high-efficiency solution for air filtration in industrial environments, including textile and nonwoven applications, designed to handle large volumes of air containing dust, fibres, and fine particulate. Thanks to its compact and durable construction, it ensures consistent performance even under demanding operating conditions, helping maintain clean and safe working environments.
Its modular design and fully automated operation make it ideal for integration into both new and existing systems, offering reduced maintenance requirements and long-term operational reliability.
The rotary drum filter consists of a cylindrical metal mesh structure covered with filter media, available in different materials depending on the dust concentration and process requirements. The drum rotates continuously by means of a gear motor driving an anti-friction coated wheel, ensuring stable and uninterrupted operation.

Contaminated air is drawn through the drum from the outside to the inside by the negative pressure generated by the fan. During this process, dust and fibres are retained on the external surface of the filter media. Automatic cleaning is performed by one or more suction nozzles that move axially along the drum, continuously removing accumulated particles and conveying them to dedicated collection systems.
Clogging is monitored by a differential pressure switch or pressure transmitter, which measures the permeability of the filter media and signals when replacement is required.
For high airflow applications, the system is also available in a modular configuration, providing maximum filtration surface area while maintaining compact overall dimensions.enute.
