Non-ventilated sampling hood
This hood allows defined sampling of flow area sources with very low discharge speeds (e.g. biofilters and ventilated compost piles).
The volume of the exhaust air flow is guided through the hood and the chimney, and is consolidated.
The sampling hood has a base surface area of 1 m2 and a chimney with a diameter of 150mm.
It is easy to transport, as the chimney can be detached from the body of the hood by loosening the four knurled nuts. There are also carry handles on the body of the hood.
As the hood’s susceptibility to side-winds is a particular problem at the chimney outlet, a wind collar is used here to keep the flow conditions in the hood constant.
The non-ventilated sampling hood is fully compliant with:
- EN 13725
- VDI 3880
- For sampling on ventilated surfaces, such as a biofilter
- Can be taken apart for easy transportation
