6 and 1-fructan exohydrolase that can degrade both inulin and levan-type fructans, such as phlein, levan, neokestose, levanbiose, 6-kestose, 1-kestose, inulin, and 1,1-nystose. Hydrolysis of terminal, non-reducing (2->1)- and (2->6)-linked beta-D-fructofuranose residues in fructans. Associated to the cell wall. Expressed in seedlings and leaves, and, to a lower extent, in flowers and seeds. Belongs to the glycosyl hydrolase 32 family. Seems to not have any beta-fructofuranosidase activity.
