possible in 4 x 90

°

 (extraction, ash bin)

Supplied with:

■ 

1 flue gas cyclone

■ 

1 ash container 24 USG (90 L)

CAUTION

The effects of heat can create dangerous conditions.

The flue gas cyclone minimizes dust emissions and is 

designed as a multi cyclone with axial function. 

The de-duster is fully insulated and has three covers for 

cleaning. The flue gas cyclone for 300 RF is an option, 

and is not generally required when burning pellets but is 

recommended when burning chips.
The crude gas chamber is cleaned via the side cleaning 

cover. The clean gas chamber is cleaned via the upper or 

back cleaning cover (unused blower connection).
The ash box has a carriage and is connected to the 

de-duster with quick-action fasteners. It can easily be 

pulled out for emptying. The blower can be installed either 

on the side or the top.
