CleanAir Europe offers the COMDE DERENDA LVS 3.1 low volume sampler for rental which collects fine particles on sampling filters in accordance with EN 12341: 2014 (PM 10 and PM 2.5). To this end, a vacuum pump draws in ambient air and the sampler breaks down the fine particles suspended in the air in a sampling outlet. The air containing the fine particle fraction then passes through the filter, where the particles are collected and made available for subsequent gravimetric evaluation or analysis. The volumetric flow is measured with an orifice plate and electronically adjusted with an accuracy of ≤ 2%.
Key points :
• Device according to EN 12341: 2014
• Simple operation with thumbwheel
• Electronically controlled volumetric flow
• Operating modes: TIME, PERIOD and QUANTITY

• RS-232C interface
Type LVS 361 is classified as a reference unit according to European directives EN 12341 and EN 14907. The air flow volume when collecting the PM10 or PM2.5 fractions amounts to 2.3 m3 / h. The device is equipped with a 4 m³ rotary vane vacuum pump. The maximum vacuum at the filter is 300 mbar. The maximum airflow when using a fiberglass filter is 35 m³ / h.
