A fan is coupled to the motor by a first member configured to provide a rotational input speed. A liquid-gas separator is coupled to a second member configured to provide a rotational output speed. A speed reduction device is coupled to the first and second members. The speed reduction device is configured to provide a rotational output speed that is less than the rotational input speed. In another embodiment, the fan is arranged in the housing and is directly coupled to the motor by the first member. The fan includes first and second sides respectively including first and second pumping elements. A first waste collection line fluidly connects a urinal to the first side. A second waste collection line fluidly connects a fecal storage container to the second side. ## Claims ### Claim 1 A waste collection unit comprising: a motor supported by a housing; a fan coupled to the motor by a first member configured to provide a rotational input speed; a liquid-gas separator coupled to a second member configured to provide a rotational output speed; and a speed reduction device coupled to the first and second members, the speed reduction device configured to provide a rotational output speed that is less than the rotational input speed. ### Claim 2 (depends on 1) The waste collection unit according to claim 1, wherein the housing includes a fan housing portion enclosing the fan, and a separator housing portion enclosing the separator, the speed reduction device arranged in the housing. ### Claim 3 (depends on 2) The waste collection unit according to claim 2, wherein the speed reduction device is a gearbox. ### Claim 4 (depends on 3) The waste collection unit according to claim 3, wherein the rotational input speed is approximately three to four times the rotational output speed. ### Claim 5 (depends on 2) The waste collection unit according to claim 2, wherein the first member is a first shaft that is supported at one end by a bearing mounted to the housing and at another end by the speed reduction device. ### Claim 6 (depends on 2) The waste collection unit according to claim 2, wherein the second member is a second shaft that is supported at one end by the speed reduction device and at another end by the separator. ### Claim 7 (depends on 6) The waste collection unit according to claim 6, wherein the speed reduction device includes an opening fluidly connecting the separator to the fan and configured to provide a gas from the separator to the fan. ### Claim 8 (depends on 1) The waste collection unit according to claim 1, comprising a waste collection line fluidly connected to the fan and configured to provide a gas, the fan configured to pump the gas from the waste collection line to an outlet. ### Claim 9 (depends on 8) The waste collection unit according to claim 8, comprising a filter fluidly connected to the outlet and configured to neutralize the gas. ### Claim 10 (depends on 8) The waste collection unit according to claim 8, wherein the waste collection line is fluidly connected to a fecal matter storage container. ### Claim 11 (depends on 8) The waste collection unit according to claim 8, wherein the waste collection line is fluidly connected to a urinal. ### Claim 12 (depends on 1) The waste collection unit according to claim 1, comprising a first waste collection line fluidly connecting a urinal to the fan, and a second waste collection line connecting a fecal matter storage container to the fan, the fan configured to provide gases from the first and second waste collection lines to a common outlet. ### Claim 13 (depends on 12) The waste collection unit according to claim 12, wherein the fan includes first and second sides respectively including first and second pumping elements, the first and second pumping elements respectively in fluid communication with the first and second waste collection lines. ### Claim 14 (depends on 13) The waste collection unit according to claim 13, comprising a urine collection container fluidly connected to the separator. ### Claim 15 A waste collection unit comprising: a motor supported by a housing; a fan arranged in the housing and directly coupled to the motor by a first member configured to provide a rotational input speed, wherein the fan includes first and second sides respectively including first and second pumping elements; and a first waste collection line fluidly connecting a urinal to the first side; and a second waste collection line fluidly connecting a fecal storage container to the second side. ### Claim 16 (depends on 15) The waste collection unit according to claim 15, wherein the first and second pumping elements are arranged in separate pumping chambers, and the fan is connected to a common outlet provided in the housing. ### Claim 17 (depends on 16) The waste collection unit according to claim 16, comprising a filter fluidly connected to the outlet and configured to neutralize gases from the first and second waste collection lines. ### Claim 18 (depends on 15) The waste collection unit according to claim 15, comprising a liquid-gas separator arranged within the housing and coupled to a second member and configured to provide a rotational output speed, the separator fluidly connected to the first waste collection line, a speed reduction device coupled to the first and second members, the speed reduction device configured to provide a rotational output speed that is less than the rotational input speed, and the speed reduction device includes an opening fluidly connecting the separator to the fan and configured to provide a gas from the separator to the fan.
