Abstract: A dispenser includes a housing, an aperture within the housing, a receptacle within the housing, and a pneumatically driven actuator. The receptacle removably receives a reservoir, such that when the reservoir is received by the receptacle, an outlet port of the reservoir is exposed through the aperture. When the pneumatically driven actuator is actuated, the pneumatically driven actuator provides a dispensing force that induces a flow of a predetermined volume of fluid within the reservoir through the exposed outlet port of the reservoir and dispenses the predetermined volume through the aperture. In some embodiments, the dispenser includes an internal pneumatic source. The internal pneumatic source may include an air compressor. The dispenser may include a pneumatic input port that receives a pneumatic hose. The dispensing force translates a piston in the reservoir a predetermined distance. The predetermined distance may be linearly proportional to the predetermined volume of dispensed fluid.
