Deflections in other damper widths(Iess than 4S"[1219])at <br /> higher pressures shown will result in blade deflection substantially less than 1/180 of <br /> Q36" span. <br /> (914) <br /> oQmC4 Ruskin Company certifies that the CD50 <br /> Z4.. oe�mn� shown herein is licensed to bear the AMCA <br /> 3 (610) �T��� Seal.
