The cyclone sampler is designed for dust (aerosol) sampling to the respirable convention as defined in standard EN481:1993, using HSE method MDHS 14/3 “General methods for sampling and gravimetric analysis of respirable and inhalable dust”.

Design flow rate is 2.2 l/min, giving a 50% sampling efficiency (cut point) at 4.0μm (micron) particle size.

The SKC plastic cyclone is manufactured from conductive plastic which dissipates electrical charges to the surrounding atmosphere and prevents static interference on the collection of the dust particles.

The filter is held within a re-usable plastic cassette, which is supplied complete with a metal filter support grid and a sealing clip to prevent contamination of the sample during transport for laboratory analysis.

For detailed instructions on air sampling in general and use of the cyclone sampler in particular refer to SKC’s 224-G1 Step by Step Guide to Air Sampling.
