The FAS is an automatic sampling device, used for collecting dust samples in dust transport pipes, where the media is conveyed by pneumatic transport. The automatic sampling of fly ash is possible over a period of time in order to record average values of the material properties.

The power plant staff will change the bottle after the pre-set number of samples has been taken. The sampled ash can then be taken to the laboratory for analysis. The fly ash sampler can be installed directly in the transport pipeline or in the pneumatic blow unit.

The purging air and the canister are heated to prevent condensation inside the sample unit, which could otherwise result in blocking of the system.

The control box contains necessary switch buttons and PLC with touch panel for operation of sampling cycles and setting
of number of samples and time intervals.
