Penetration and Filtration

The BPT-02 and PFT-02 devices test the penetration and filtering properties of fabrics, filters and face masks.

 

BPT-02

Properties:

  • Penetration of blood into medical tissue
  • Immigration of synthetic blood through negative pressure into the fabric
  • For flat fabrics such as mask gowns, surgical gowns, etc.

Advantages:

  • Easy to perform
Pressure Difference 0 – 40 kPa
Test Area 28,,26 cm²
Standards ASTM F 1670, ASTM F 1671, ISO 16603:2004, GB19082, YY/T 0700

PFT-02

Properties:

  • Particle -filtration efficiency test of fabrics, such as workwear, med. protective clothing, respiratory masks, filters, etc.
  • Set amounts of cold aerosol are blown through the fabric.
  • With salt or oil aerosol generator, as well as aerosol neutraliser
  • Incl. laser-controlled particle counter
  • Pneumatic clamping

Advantages:

  • Simple implementation
Flow 10 – 100 l/min
Particle Diameter Salt Particle(0.075±0.02)μm
Oil drops(0.185±0.02)μm
Measurement Range 0.001-100 mg/m³
Standards GB24539, GB 19082
