Roof and wall fans

How to ensure that the installed fan will perform with the stated capacity and sound data

EXHAUSTO's roof and wall fans (VVR, DTH and DTV) are measured and documented by the same methods. The documentation has therefore been gathered together here, and includes assumptions and calculation examples for:

Sound data: Under assumptions for sound data you can find general information on sound measurement and an example of sound data calculation.

Under assumptions for capacity measurements: you can find general information on measurement setups and an example of a capacity diagram.

EXHAUSTO recommends that you undertake a precise calculation in EXselect.
