Pulse-Bac® vacuum equipment comes equipped with patent pending Hepa rated H-13 P.T.F.E. coated Spun Bond Polyester twist on filters. Filters are 100% non-woven polyester, 10x more durable than paper or sock filters, and able to capture dust particles as small as .3 micron. Filters have a high burst strength and are resistant to abrasive water, heat, and other chemicals.

 When using a filter pulsing system, filters made from a SBP media with a P.T.F.E coating are the best material to use.  The SBP  surface does not permit particles to become embedded  in the material as in the case of felt or paper. Since the media is produced from a continuous fiber, and is not prone to fiber migration or linting, SBP filters are much more rugged than paper filters, allowing pulse cleaning of the spun bond media to be  more effective.   

   When operating vacuum equipment for dust critical applications, it is very important to know the true filter fractional efficiency of the filters in use. When competitors specifications say they capture 99.99% @ .3 micron, what is really being stated is the media's flow response at 1 CFM  per sq. ft of air  @ .5 inches of *w.g. lift.  Since 99.99% of vacuum equipment operate at more than 1 CFM, and have a greater lift than .5 *w.g., this measurement  is void once the vacuum is operating. For example, the Pulse-Bac 1300 has 135 CFM per sq.ft. with a lift of 80 *w.g.   The efficiency of the filter is directly related to the velocity of the air moving through it from the vacuum,  without this specific information, a rating at .3 micron may not be so.

   We at CDCLarue™ want our customers to be educated to what they can reasonably expect to be filtered out when using Pulse-Bac® vacuum equipment. When purchasing vacuum equipment for dust critical operations, be sure that you know the fractional efficiency data for the filters, not a standard math equation for a efficiency rating at 1 CFM.  For fractional data on Pulse-Bac vacuum equipment, please call us at 866.954.9700
