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.
