Fan Stack

 

Industrial fan casings consist of inlet fan ring which accelerates flowing air steam and the cylindrical portion - the impeller work area. Fan housing duty is to shape up the medium stream in order to achieve the best fan unit flow parameters. Fan unit housing is made of FRP. Specially elaborated fan ring or fan stack structure provides required stiffness of the units. Despite of low weight fan ring and fan stack features high stiffness, provided by specially engineered stiffening ribs system based on sandwich structure.

Thanks to the latter both internal and external fan stack and fan ring surfaces are smooth and shiny thus improving air flow parameters and help to keep the unit clean over the time of operation.

Well elaborated down to the every detail, lightweight sandwich structure of the fan stack or fan ring segment effectively lowers manufacture cost, facilitates handling and assembly in order to reduce work time of Contractor team on site.

High manufacture precision of every single fan housing segment provides perfect roundness of impeller work area and optimized fan blade tip clearance. Fan housing is furnished with special ribs additionally compensating aerodynamic force resulted in impeller rotation.

All connection accessories of vertical segment flanges are made of PN OH18N9 (DIN 1.4301) stainless steel.

Fan housings are suited for work temperatures ranging from - 25 up to do + 65 ^oC.

Fan housings can be made in any of RAL color palette. Our RAL standard product color is pale grey (RAL 7035)
