摘要： A negative pressure filtration device is used in conjunction with a containment enclosure for the removal of hazardous material such as asbestos insulation surrounding pipes in habitable buildings. The inventive negative pressure filtration device generates a negative pressure within the containment enclosure, which negative pressure is quantitatively adjustable and capable of being continuously monitored by the user. Advantageously, the negative pressure filtration device is small, lightweight, portable, battery-operated and reliable, for use in a wide variety of hazardous material removal scenarios. The portability and versatility of the negative pressure filtration device is achieved through the use of operational vacuum pressures and air flow volumes much smaller than those of known systems.
