Pulse-Bac® vacuum equipment comes equipped with patent pending 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 .1 micron. Filters have a high burst strength and resistant to abrasive water, heat, and other chemicals. The filters media is dimensionally more stable than paper filters and can be washed with high pressure water, dried and reused.  Simply put, P.T.F.E. coated SBP  filters are the best filters available when working with dust critical applications and vacuuming up fine dust particles. 

 When using a filter purging system, Filters made from a SBP media with a P.T.F.E coating is the best material to use.  The SBP pleats are spaced apart on the filter and the surface does not permit the particles to become embedded 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,  and allow pulse cleaning of spun bond media  to be  more effective.   

   When operating vacuum equipment for dust critical applications, it is very important to know the true filtration efficiency of the filters in use. When our 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  lift greater than .5 *w.g. this measurement  is useless once the vacuum is operating. 

  For example, the Pulse-Bac 1300 has 135 CFM per sq.ft. with a lift of 80 *w.g.  What you need to know they do not tell you, and that is the efficiency of the filter is directly related to the velocity of the air moving through it from the vacuum,  therefore the information they give is worthless once the vacuum starts.

   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 click on the link below, fill out the form, and in "other information" type filter data request.  **water glass**
