Abstract
A vane type air pump having vanes with an edge that slidably engages the inside of a cylindrical casing and sides that slidably engage carbon sealing elements. The vanes are constructed of pre-impregnated glass cloth with the warp and weft positioned at acute angles to the sealing element to provide less and smoother wear on the sealing element and inhibit air leakage. A heavy density weave of glass cloth also reduces the wear.
