The plurality of sewn loops are secured to the gather so that the internal volume of the collector bag, when disposed on the collector frame, is at least about 90 percent of a maximum volume of the collector frame. ## Claims ### Claim 1 A collector unit comprising: a fabric collector bag formed to define an internal volume; a collector frame; a plurality of sewn loops being disposed about an outer periphery of said collector frame; and a gather of fabric of said fabric collector bag at each of said plurality of sewn loops, said gather of fabric being disposed about an inner circumference of said collector frame, each of said plurality of sewn loops being secured to said gather so that said internal volume of said fabric collector bag before use is at least about 90 percent of a maximum volume of said collector frame and so that said internal volume is equal to at least about 115 percent of said maximum volume of said collector frame during use of said fabric collector bag. ### Claim 2 (depends on 1) The collector unit of claim 1, wherein said fabric collector bag and said collector frame have a substantially isosceles trapezoidal cross sectional shape. ### Claim 3 (depends on 1) The collector unit of claim 1, wherein said fabric collector bag and said collector frame have a substantially rectangular cross sectional shape. ### Claim 4 (depends on 1) The collector unit of claim 1, further comprising a vent screen releasably secured to said fabric collector bag. ### Claim 5 A collector unit comprising: a fabric collector bag formed to define an internal volume; a collector frame; a plurality of sewn loops being disposed about an outer periphery of said collector frame; and a gather of fabric of said fabric collector bag at each of said plurality of sewn loops, said gather of fabric being disposed about an inner circumference of said collector frame, said gather of fabric having a length that is at least equal to a length of each of said plurality of sewn loops, wherein said internal volume is equal to at least about 115 percent of a maximum volume of said collector frame during use of said fabric collector bag. ### Claim 6 (depends on 5) The collector unit of claim 5, wherein said gather of fabric is in contact with said collector frame during use of said fabric collector bag. ### Claim 7 (depends on 6) The collector unit of claim 6, wherein said internal volume is about equal to a maximum volume of said collector frame minus the volume of individual tubes of said collector frame. ### Claim 8 (depends on 5) The collector unit of claim 5, wherein said internal volume is equal to at least about 120 percent of maximum volume of said collector frame during use of said fabric collector bag. ### Claim 9 (depends on 5) The collector unit of claim 5, wherein said internal volume is equal to about 125 percent of said maximum volume of said collector frame during use of said fabric collector bag. ### Claim 10 (depends on 5) The collector unit of claim 5, wherein said fabric collector bag and said collector frame have a substantially isosceles trapezoidal cross sectional shape. ### Claim 11 (depends on 5) The collector unit of claim 5, wherein said fabric collector bag and said collector frame have a substantially rectangular cross sectional shape. ### Claim 12 (depends on 5) The collector unit of claim 5, further comprising a vent screen releasably secured to said fabric collector bag. ### Claim 13 A collector unit comprising: a collector frame having a maximum volume; and a fabric collector bag secured to said collector frame by a plurality of sewn loops at an outer periphery of said collector frame and a corresponding plurality of gathers of fabric at an inner circumference of said collector frame, wherein each of said plurality of sewn loops are secured to each of said plurality of gathers so that an internal volume of said fabric collector bag is equal to at least about 115 percent of said maximum volume of said collector frame during use of said fabric collector bag. ### Claim 14 (depends on 13) The collector unit of claim 13, wherein each of said plurality of gathers of fabric have a length that is at least equal to a length of each of said plurality of sewn loops. ### Claim 15 (depends on 13) The collector unit of claim 13, wherein said fabric collector bag and said collector frame have a substantially isosceles trapezoidal cross sectional shape. ### Claim 16 (depends on 13) The collector unit of claim 13, wherein said fabric collector bag and said collector frame have a substantially rectangular cross sectional shape. ### Claim 17 (depends on 13) The collector unit of claim 13, further comprising a vent screen releasably secured to said fabric collector bag. ### Claim 18 (depends on 13) The collector unit of claim 13, wherein said internal volume is equal to at least about 120 percent of said maximum volume of said collector frame during use of said fabric collector bag. ### Claim 19 (depends on 13) The collector unit of claim 13, wherein said internal volume is equal to about 125 percent of said maximum volume of said collector frame during use of said fabric collector bag.
