The invention relates to a rack (21, 27, 28) for supporting electrostatic filter plates (22, 23) of an electrostatic filter (20). The rack (21, 27, 28) is an elongated member comprising a plurality of notches (11) on a longitudinal side of the rack (21, 27, 28) for supporting a plate (22, 23) arranged to a notch (11). The rack (21, 27, 28) further comprises a slot (26) for adhesive arranged to be used at least for attaching the plates (22, 23) to the rack (21, 27, 28). The slot (26) is arranged on the opposite side of the rack (21, 27, 28) than notches (11). There is also an opening (24) in the first group of plates (22) at that point where the plates (22) are aligned with the voltage supply rack (28) but which are not attached to that rack (28). The invention further relates to an electrostatic filter (20) comprising a plurality of racks.

The invention relates to a supply air device (20) comprising: a nozzle channel structure (21 ) comprising at least one nozzle (23) and a mixing chamber (24). The nozzle channel structure (21) is arranged in a distance from the bottom (26) of the device forming a circulation space between the bottom (26) of the device and the nozzle channel structure (21). Primary air is led to the nozzle channel structure (21) and further to the mixing chamber (24) as at least one primary air flow. Primary air flow entrains secondary air to flow to the mixing chamber (24) and at least a part of secondary air flows to the mixing chamber (24) through the circulation space, wherein the primary air and secondary air are arranged to be mixed in the mixing chamber (24) before flowing out of the supply air device (20). The invention further relates to a nozzle channel structure (21) arranged to be used in a supply air device (20).
