> Drastic increase of detection thresholds of rare pathogens in large volumes (Aspergillus, Staph. aureus, Clostridium difficile,..) hospital hygiene sampling volumes do not reach more than 1 cubic meter, an insufficient  sampling volume to evaluate surgical roooms or  a rooom under laminar flow so as to reach the contamination threshold targeted by hosptial hygienists, hematology, transplant and intensive care units of 1 aspergillus mold spore per cubic . SASSS 3100 allows up 350 LPM for more than 20 hours if necessary, increasing detection thresholds of  rare pathogens diffused in ultra-clean environment and in large volumes.

> No cross-contamination risks, no more pathogen release through the contaminated fan blades or housing  of air samplers. Easy internal and outside surfaces exposed to microorganisms, including fan blades and ventilator housing. Ventilator housing from impactors and other airsamplers are becoming after a while contamination sites able to release and seed in ultra-clean environment pathogens originally not present on site.  Sass 3100 ventilator housing is easily unscrewed and removable, fan blades can be dipped or sprayed and wiped with biocide. Removable housing can be autoclaved or dipped in biocide. 

rapid removal of ventilator housing for its decontamination

> 18 cubic meter/hour up to more than 20 hours continuous sampling without rapid filter plugging.

Due to a very low density of electrostatic dipole fiber filter with more than 95% void volume, the  airflow stream coming in and out of the filter are not  hindered, but microscopic electrostatic dipole fields are sufficiently powerfull to divert from air stream and capture on its" permanent magnet" fibers a large array of different aerodynamic sizes of microorganisms ranging from sub-micron virus pellets to large mold spores. 

 > hig capture efficiency and retention of particles < and ≥ to 1μm

Sass 3100 capture rate for aerodynamic sizes from 300 nm up to 5 microns in a airflow of  300l/min.

Sub-micron H1N1 and other RNA virus dropplets nuclei, cannot be collected by liquid airsamplers nor by classical plate count impactors. Not influenced by gravity nor sedimentation physical laws, these viral pellets can remain floating for  days in rooms. Even if these sub-micron pellets are collected by airsamplers, these are release back immediatelly into the air outlet.  The only possible capture technologyfor such sizes  is the Sass 3100  using microscopic electrostatic dipole charged fibers, able to divert from airstreams these sub-microns particles and to capture them on their fibers. 

 > Excellent recovery rate of collected microorganims in liquid format.

Microscopic permanent electrostatic dipole field capture combined with  of electrostatic filter surfactant saturation associated with a calibrated liquide sonication of filter allows an excellent release and recovery of captured microorganisms in liquid format.
