A pneumatic fluid transfer device employs compressed air as its power source to move liquids from within a drum or similar container. This mechanism is commonly utilized for dispensing various fluids, ranging from water-thin solvents to viscous oils, efficiently and safely.
Its intrinsic safety in hazardous environments due to the absence of electrical components near the fluid source is a primary advantage. Furthermore, the relatively simple design contributes to ease of maintenance and a long operational lifespan. Historically, such devices provided a safer and more controlled alternative to manual pouring or siphoning methods, reducing spillage and worker exposure to potentially harmful substances.
