The third era vacuum lifter or uses multi-stage ejector pump and metal filter. Our products are the third era products. We develop the vacuum conveyor follow the combination of the aerospace and international GMP criterion strictly. Our technology has achieved international advance level. Our products can solve the stratification of powder and granules, and eliminate the static electricity. Characteristic: ---Using compressed air as primary energy sources ---According with GMP standard ---Solving the stratification of powder and granules ---The filters made of Ti will never be jammed and be abraded ---Eliminate the static electricity ---Made of nontoxic and corrosion resistant materials ---Leakage free capsule, to prevent cross contamination ---Materials are not adhering to the inner surface of the conveyor ---Intelligent control and high automation ---Modular structure, easy to clean and dismantle ---Small and light ,easy to install ---Low noise and free from vibration ---Energy saving and low running cost. QVC conveying system consist of material container, pipeline, vacuum conveyor, control system and so on. The max distance to convey is 30m in height or 90m in length and the max conveying capability can reach 18 t/h.   Main Technical Specifications:

  Conveying model:
Pneumatic conveying systems are divided into four categories: positive pressure system, vacuum conveying system, upgrading system and  fluidised beds.

Conveying system	Advantages	Disadvantages	cost
			equipment cost	running cost
Positive pressure	High capacities Long distance conveying	Risks of leakage Heavy installations Expensive components Wear on material and system	High	High
Vacuum conveying system	No leakage of material Simple to install Dustless Easy to control	Limited conveying distance Limited capacity Usually intermittent operation	Low	Low
Upgrading system	No leakage of material	Hard to control Equipment complex Big Short distance to convey	High	Common
Fluidized beds	Angle of conveying from only 2?C3?㠳lope No moving parts	Dusty conveying Open system	High	High
