Single-stage Venturi ejector PVR series

Adjustable vacuum generators conveyor pvr 25 and pvr 50 ,based on the Venturi principle can be used continuously without any heat generation.The ejector in this device is adjustable,having larger flow diameter unlike the prior version.The new technology enables the device to modify the capacity and vacuum level without effecting the air supply pressure level.The actual performance of the vacuum generator is the basic point upon which the compressed air consumption depends. With the only difference of allowing overcome of much higher level differences,vacuum generators are much the same as the flow generators as these too allow sucking and transferring products of various nature with no interference.What makes this possible is the special shape of these adjustable vacuum generators,as well as their straight-flow working principle.A silencer screwed on the exhaust connection is provided which reduces the extreme high noise of this equipment to a great extent. The device proves to be an excellent piece owing to a good filtration of the compressed air supply which makes them maintenance free.Available in anodized aluminium and stainless steel,the device works without any electric supply.
