PMFT 1000 M

Test of respiratory masks better than the standard. Exact analysis of filter mask efficiency from 145 nm up to 40 µm.  SARS-CoV-2 size approx. 120 nm - 160 nm.

Description

Test of respiratory masks better than the standard with additionally exact analysis of filter mask efficiency for SARS-CoV-2 (size approx. 120 nm up to 160 nm). Display of efficiency from 145 nm.

  • Test rig working principle better than EN 143, EN 149 and EN 13274-7
  • Equivalent to GB 2626 and 42 CFR 84 by additional software option
  • Fullfills additionally the requirements according to GB 2626 (Filter efficiency, CD 2000 discharge unit is required)
  • Testing of fractional efficiency, e.g. efficiency in whole size range of 145 nm up to 40 µm
  • Exact analysis of filter and filter mask efficiency for SARS-CoV-2 (size approx. 120 nm up to 160 nm). Efficiency also displayed at 145 nm
  • Future proof: Works with any kind of aerosol without adjustments
  • Further measurement of differential pressure, e.g. as well within different face velocities
  • Face velocity adjustable between 1.5 - 50 cm/s
  • Product capable of fast quality assurance AND continuous optimization in R&D (display of size distribution)
  • Individual face mask adapter for your product
  • Attractive 2 years maintenance package for availability of test rig
  • Can be operated as Mas Q-Check with optional Mas-Q-Head

PMFT 1000 M is based on Palas® MFP 1000.
