Featured HoodTo protect operators working in a 3D printer environment, Airfiltronix has developed a filtration system to remove the nanoparticles created during the formation of 3D objects.
Featured ProductThe Scavenger Series portable fume/particle extractors are an inexpensive solution to all small scale, yet potentially hazardous, fume and particle problems.
Featured ProductThe HS-5000 is a completely self contained, filtered-air workstation and work surface in one package. A back baffle provides horizontal linear air flow with less turbulence.
Selecting the proper filter for your application.
Airfiltronix fume hoods and fume/particle extraction devices are designed to accept a series of filters including aluminum or dacron prefilters, HEPA particulate filters, activated carbon or specially treated carbon for organics, ammonia, acid gases, formaldehyde, radioactive iodine and mercury.Proper filtration is a combination of two factors. The first is matching the filter medium to the pollutant. This is accomplished through the use of material safety data sheets and any other means available for identifying the precise nature of the pollutant. The second involves determining the capacity of the filter as it relates to the amount of pollutant it will be exposed to. This is more complicated. However, with proper information this can be done with reasonable accuracy. Ideally, we would expect filters to function for about two months or more to consider an application feasible. The range could be from one month to one year depending on conditions and frequency of use. HEPA filters, when properly applied, typically last from six to twelve months. They are generally used in conjunction with a pre-filter to extend the life of the HEPA filter. The average life expectancy for carbon filters is four to six months. This is based solely on our statistical average and is never implied as a guarantee. Each situation should be evaluated and our application engineers will offer an "expected range" of filter life. Customers should implement a regular monitoring program to test the system's effectiveness.
