Product Description

Over these 26 years in this domain, we manufacture, export and supply Low Flow Air Sampler. The offered sampler is manufactured using best quality components and sophisticated techniques under the stern guidance of our deft professionals. This sampler is used to find out the concentration of particulate matters having less than 10µ within the atmosphere. Our quality inspectors also test this sampler on defined quality parameters to ensure its flawless nature. Further, we offer this Low Flow Air Sampler to the clients at an economical price range.


  • Compact and portable design

  • Easy to use

  • Optimum performance

  • Longer service life 


Model PEM– LFAS10 is an advanced Respirable Dust Sampler designed to meet EPA method for determination of particulate matter less than 10µ (PM – 10 standard) in the atmosphere.  The sampler can also be used for measurement of SPM by using TSPM Sampling option in lieu of 10µ sampling inlet.  For collection of particulates less than 10µ, air is first sampled through an improved louvered inlet (as per EPA) at 16.7 LPM, which separates the finer particulates to a required cut point (10µ).  The air is then drawn into a filter holder containing a 47 mm dia. Whatman GF/A filter paper which collects all particulate below 10µ.  Flow rate is regulated to ± 3% of set flow and volume is integrated online.  Both these values are displayed digitally. RSPM concentration is calcu lated from the weight increase of the filter paper and volume of air sampled.
