Photocatalytic filters and fabrics
Photocatalytic filtration activated by titanium dioxide offers a simple, natural method to reverse contamination, maintain surface cleanliness, and purify the air. This powerful technology is designed to abate odors, neutralize microbes, and break down volatile organic compounds (VOCs) and chemically active agents.
The Depurex filter media is an advanced multi-layer non-woven system, featuring a core of high-efficiency activated carbon microspheres. The substrate is integrated with nanomaterial-form titanium dioxide: this technology ensures uniform adhesion of the treatment to the fibers while preserving the fabric's original permeability.
Depurex photocatalytic activated carbon filters represent the most advanced evolution of this technology, combining, in perfect synergy, the advantages of activated carbon with the regenerative power of photocatalysis.
The Depurex hybrid filter fabric provides the following advantages:
- Higher Performance Stability: Activated carbon captures and concentrates pollutants on its surface with extreme precision, decreasing the risk of desorption.
- Photocatalytic Decomposition: The action of UV rays on titanium dioxide triggers a photocatalytic process that radically breaks down the adsorbed VOC (Volatile Organic Compounds) molecules.
- Self-Regeneration: This cycle does not merely eliminate harmful agents, but continuously regenerates the activated carbon, drastically extending the filter's life cycle and efficiency.
The Outcome.
Pollutants are converted into harmless water vapor and carbon dioxide; inert mineral residues are safely trapped within the carbon, ensuring purified air.

Photocatalytic fabrics
Non-pleated, custom-cut.
Depurex photocatalytic filter media is also available in a flat sheet version (non-pleated), with customizable heights and lengths.
It is the ideal solution for covering large surfaces or as a compatible replacement for existing systems.
Photocatalytic filter cartridges
Activated by natural sunlight
Thanks to the pleated fabric configuration, these compact cartridges offer an unbeatable footprint-to-performance ratio: they are capable of treating flow rates up to 500 m3/h with a footprint of only 600×370 mm.
By harnessing sunlight as a natural activator for photocatalysis, the system delivers maximum performance at minimum cost. It is the ideal solution for those seeking effective reduction of odors and atmospheric emissions without the complexity of extreme process control.
Installation is immediate: simply prepare a counter-flange at the emission point and secure the filter through the central hole using a simple wing nut. The integrated gasket ensures a perfect airtight seal.
Multi-filter photocatalytic systems
Activated by artificial light sources
For the most demanding applications—where natural light is unavailable or insufficient, or where airflows and pollution levels are particularly high—we offer a solution with integrated UV LED lighting.
The system, appropriately sized for the specific application, is housed in an optimized enclosure, internally partitioned to separately manage the intake and filtered air.
This simple yet extremely effective configuration already includes all necessary electronics, featuring transformers and UV LEDs calibrated to the ideal frequency to maximize photocatalysis.
The system can also be equipped with UVC LEDs for total air sanitization.
Panel Filters and Customized Solutions
Custom-made
We manufacture photocatalytic fabric panel filters in the specific dimensions required by the customer's application, as well as specialty systems where photocatalytic filtration is combined with other filtering technologies to achieve ultra-high performance levels, unattainable with other systems.
A customized product ensures perfect compliance with technical requirements and provides a business advantage through complete control of spare parts management.
