TITANIUM DIOXIDE photocatalytic filters.
Depurex photocatalytic filters are made of a multilayer of non-woven fabric containing an intermediate layer of high efficiency activated carbon microspheres; one side of the media is treated with high quality titanium dioxide.
ALL air then passes through the media and ALL pollutants (not only VOCs) are retained by activated carbons and come into contact with titanium dioxide; UV rays have time to activate photocatalysis and break down the pollutant molecules of the retained VOCs, regenerating the carbons.
Since 2011, we have been designing and manufacturing customized photocatalytic filters intended for applications requiring high performance in air treatment.
In fact, only photocatalytic technology can guarantee high levels of purification over a wide range of pollutants and, if necessary, even a sanitizing effect by means of UVC rays.
Odor abatement, purification from volatile organic compound pollutants, and bactericidal sanitization: in one filter device.
Benefits that are calibrated to the specific requirements of the specific product, whose purification needs we analyze, the scope for which the application is intended, and, taking into account the dimensional limitations of the product, we design the best possible solution.
By analyzing the data on the air quality to be treated, we are able to predict the frequency of filter replacement according to the desired results.
A customized product ensures not only perfect compliance with technical requirements, but is also a commercial advantage by allowing complete control of spare parts management.
The simplest and most economical solution to take full advantage of the benefits of photocatalytic filtration.
The filter is constructed by placing the titanium dioxide-treated fabric side outward; photocatalysis is activated by sunlight.
The ideal solution for applications that do not require extreme process control, such as, for example, abatement of atmospheric emissions of odorigenic emissions.
Available in different sizes, up to a maximum flow rate of about 500 m3/h.
filters with activation by artificial lighting
On the other hand, when it comes to cases where filtration is carried out inside a machine or plant, it is necessary to provide a source of artificial lighting, which, depending on the situation, can be through LEDs or traditional lamps.
The 600 series filter can be realized with a UV lamp/led unit inside and is extremely flexible in plant sizing: each filter is self-contained and therefore plant sizing can be designed on the volume and concentration data of pollutants to be treated specifically. Each cartridge in the 600 series can effectively treat about 500 m3/h.
Custom designs are our specialty, and therefore, we can design and manufacture filter systems for special needs.
Systems where photocatalytic filtration is combined with other filter technologies to achieve otherwise unobtainable performance.
