21 . A diffuser assembly comprising:
a tubular chamber having a groove on an interior wall of the tubular chamber;
a circumferential compression fit diffuser disc retained in the groove, wherein the circumferential compression fit diffuser disc is retained by its own spring pressure resisting force.
22 . The assembly of claim 21 , wherein the circumferential compression fit diffuser disc is domed when retained in position in the tubular chamber and is repositionable or removable by pushing on a concave side of the dome.
23 . The assembly of claim 21 , wherein a depth of the groove facilitates an inversion of the dome from the dome based upon insertion.
24 . The assembly of claim 21 , further comprising a plurality of grooves on the interior wall of the tubular chamber.
25 . The assembly of claim 21 , wherein the groove is a first groove, further comprising a second groove on the interior wall of the tubular chamber, wherein the circumferential compression fit diffuser disc is movable between the first groove and the second groove and the dimension of the tubular chamber is adjustable based upon a location of the circumferential compression fit diffuser disc in either the first groove or the second groove.
26 . The assembly of claim 21 , wherein the groove is deep enough to permit complete relaxation of the circumferential compression fit diffuser disc.
27 . A diffuser comprising a plurality of apertures for diffusion of material therethrough, wherein the diffuser comprises a disc configured for circumferential compression, and has a diameter when uncompressed which is slightly greater than an area into which it is placed.
28 . The diffuser of claim 27 , wherein the disc has a plurality of recesses spaced about the circumference of the disc.
29 . The diffuser of claim 27 , wherein the disc has a radial array of spaced apart disc segments.
