A V-bank air filter having a high air flow rate with low pressure drop is provided. In one embodiment, a V-bank filter includes a housing having a first pair and a second pair of pleated filter elements arranged in a vee configuration and comprising a unitary disposable filter. A centerline defined by the first pair of pleated filter elements defines an acute angle with a centerline defined by the second pair of pleated filter elements.
A pocket filter assembly includes a frame structure having a plurality of filter pocket openings and a corresponding plurality of filter pockets, each filter pocket having a pocket mouth securely sealed in a corresponding filter pocket opening. The frame structure includes an outer subframe and a corresponding inner subframe connected and locked to each other by means of locking elements at locking positions distributed along opening portions of the subframes defining the filter pocket openings. At each locking position, the filter pocket mouths are sealed clamped and sealed between co-operating opening portions of the subframes. The locking elements include an undercut hook-shaped projection on the inner subframe and a co-operating receiving hole on the outer subframe, such that an interlock of the subframes to each other is obtained, while including filter pocket mouth material of the associated filter pocket between said projection and said aperture such that said interlock is sealed thereby.
The present invention relates to an air filter unit (1) having the shape of a tube comprising a top plate (6), having an air inlet (7) leading into the interior of the tube, whereby the top plate (6) includes fasteners (13) for removably attaching said air filter unit to a wall (2) so that the air inlet of the top plate is concentrically disposed in relation to an opening in said wall, and a sealing ring (14,15) of a resilient material surrounding the air inlet in the top plate. According to the present invention, the top plate (6) includes at least one protrusion (16) on the side thereof facing said wall (2) in use, the height of said protrusion (16) being less than the distance with which the sealing ring (14,15), when not subjected to load, projects out from the surface of the top plate.
A pleatable filter structure for use in a filter panel, containing ion exchange particles distributed within a fibrous framework is expanded to contain enough space to allow the ion exchange particles to swell or to be in a swelled state as compared to dry ion exchange particles, without additional expansion of the filter structure. A method of manufacturing the filter structure involves subjecting the filter structure to a moisture treatment in which it is exposed to a humid or water containing environment, whereby the ion exchange particles swell and cause a permanent expansion of the filter structure.

Gas turbine arrangement having an integrated filter housing and compressor bleed duct
Arrangement at a gas turbine installation for the generating of electricity, where inlet air filter housing, bleed air outlet and inlet for the vent air to the turbine housing are integrated into two units, an upper filter housing and a lower intermediate housing connected to the turbine housing. The lower intermediate housing includes a silencer for the inlet air that at the same time connects the filter housing with the turbine inlet. The compressor bleed air system is divided into two parts, one in the intermediate housing and one extending through the filter housing. The vent air for the turbine housing is drawn in through an end wall of the filter housing and down into the turbine housing through separate spaces surrounding the compressor bleed ducting in the filter and intermediate housings.
