DPM Cyclone Sampler 225-68
Operating Instructions
About the DPM Cyclone Sampler
The SKC DPM cyclone is manufactured from
conductive plastic which dissipates electrical
charges to the surrounding atmosphere and
prevents static interference on the collection
of dust particles.
An extended retaining ring and special sealing
arrangement enables the DPM cassette to be
fitted to the cyclone sampler.
In this application the purpose of the cyclone
sampler is to remove the larger, non-respirable
particles prior to the inlet of the DPM cassette
to prevent blockage of the fine impactors built
into the DPM cassette.
Design flow rate when sampling with the DPM
cyclone and DPM cassette is determined by
the performance of the DPM cassette, see
below.
About the DPM Cassette
The DPM (diesel particulate matter) cassette,
(SKC part number 225-317) is supplied pre-
assembled and sealed, and is designed for
single use.
The DPM cassette’s built in impactor
assembly screens out particles
≥
1.0 µm at
a design flow rate of 2.0 litre/min. All smaller
particles are captured on the sample filter.
The cassette also contains a blank filter.
Please also refer to the instructions supplied
with the DPM cassette.
