Disclosed is a diffuser apparatus for facilitating a reduction in fluid pressure and suppression of noise. The apparatus comprises a tubular inner sleeve, a tubular muffler and a tubular outer sleeve. The inner sleeve defines a fluid flow axis and has a plurality of inner sleeve passages. The outer sleeve has the inner sleeve concentrically positioned therein and defines a plurality of outer sleeve passages. The muffler is concentrically positioned between the inner and outer sleeves such that fluid flows radially outwardly through the inner sleeve passages, through the muffler, and through the outer sleeve passages. The muffler may be spaced from the inner sleeve so as to define a gap between the muffler and the inner sleeve. The muffler may also be spaced from the outer sleeve so as to define a gap between the muffler and the outer sleeve.
