Line Vac Conveying Rate Comparison
Infinite control of the flow rate through the Line Vac can be controlled by a pressure regulator. Kits include a pressure regulator that is sized properly for flow. The actual conveying rate is affected by the size, mass and geometry of the part to be conveyed along with the length, lift and number of bends in the hose, tube or pipe. These variables make it difficult to determine the exact conveying rate for any product, however, our Application Engineers can assist you by comparing the material you want to convey with something that has already been tested.
Many applications require that materials be transported over longer distances. The Heavy Duty Line Vac can move more material over longer lengths. They have been designed for rugged, industrial applications.
The table below gives a quick comparison of our Light Duty Line Vac, standard Line Vac and the Heavy Duty Line Vac models. For comparison, the test shows the 2" (51mm) model of each style conveying the same material over various lengths. Heavy Duty Line Vac conveys more material in less time.

EXAIR manufactures special Line Vacs suited to specific application requirements. Configurations and materials can vary according to the application requirements.
A special 3/4" (19mm) Stainless Steel Line Vac evacuates fumes from a silicone wafer etching operation.Line Vac can be engineered to retrofit existing machinery. The Line Vac (shown right) has special flanges that permit direct mounting to a machine used in the manufacturing of silicon wafers for the semiconductor industry. This flanged Line Vac is used to remove acidic vapors resulting from surface etching of the silicon wafer. Ordinarily, EXAIR’s Stainless Steel Air Amplifier would have been used since it moves much higher volumes of air. In this case, the Line Vac was the better choice since the exhaust piping was long with many bends that would have created high back pressure. The directed nozzles of the Line Vac overcame this downstream resistance.
This special Line Vac is used to fill small packets.Filling small packets with fine powders or granulated materials such as salt or sugar is done using small tubes that are gravity fed from a hopper. This works well when the material is dry, however, moist materials would often pack the tube, blocking the flow. The special funnel shaped Line Vac (shown right) created a suction on the existing tube to permit continuous product flow.
This special flanged 1-1/2" (38mm) Line Vac is made of PVDF to withstand a chloride washdown.The special flanged Line Vac (shown right) is made of PVDF, a plastic that has a high chemical resistance. In this case, the 1-1/2" (38mm) Line Vac was regularly exposed to a chloride wash, a chemical that would corrode stainless steel. QF flanges were provided on each end to allow easy removal of the conveying hoses for cleaning purposes.
A special miniature Line Vac used to vacuum microscopic debris measures the same size as a penny!The special miniature Line Vac with barb fittings (shown right) was designed for a manufacturer of integrated circuit chips. It was used to remove microscopic debris during the chip making process. This small Line Vac generated high vacuum and was the perfect configuration for the confined working space. It has also been used by another manufacturer to vacuum liquid and chips from small drilled holes.
CASE STUDY: Sanitizing Playland Balls
The Problem: Fast food restaurants and fun centers often include a cage full of plastic balls for the kids to romp around in. The balls were periodically cleaned by a service using truck mounted sanitizing equipment. Service personnel would scoop the balls into nets, carry them to the truck for washing, then lug them back to the cage - a tedious and time consuming job.
The Solution: An air compressor powering (2) Model 6087 4" (102mm) Aluminum Line Vacs was installed on the truck. With hose attached to the first Line Vac, the balls were vacuumed out of the cage and into the washer. Once sanitized, a second Line Vac and hose transferred them back to the cage. Cleaning time and expense were reduced dramatically.
Comment: The compact design and simplicity of operation were the keys to success in this application. The Line Vac also features large throat diameters for maximum throughput capability - like the large plastic balls.
CASE STUDY: Line Vac for Matrix Removal from Labeling Application
The Problem: A manufacturer applies labels to their products. After they have been applied, there is a waste stream that is referred to as “the matrix”. The matrix is the release liner that labels are affixed to in bulk format prior to being used. The normal method for taking up this waste stream was to use a winder. However, after some amount of time, the winder inevitably becomes filled. Once full, the line is stopped and the winder is manually emptied. They needed a better way to dispose of the matrix.
The Solution: The Line Vac presents a unique advantage in that it can pull the matrix from the machine and convey it out to a waste receptacle. This requires no winder, no stopping the line and no emptying. This solution freed up personnel for other tasks and increased production. The compact design and powerful operation of the Line Vac allowed it to be placed close to the generation of scrap, trim, or waste. Its powerful conveying capacity allowed it to transport the material to a remote and central location.
Comment: This application illustrates the versatility of the Line Vac product line. Commonly used as hopper loading products in the plastics industry a Line Vac is also a strong performer for applications like waste/trim removal, assembly parts conveyance, blasting media recovery, gas sampling and chip removal. Its large variety of materials and sizes makes it well suited for industrial, pharmaceutical, laboratory, high temperature and corrosive environments. No moving parts or electricity assures maintenance free operation.
CASE STUDY: Refilling a Vibratory Bowl
The Problem: A manufacturer of metal products deburrs aluminum sleeves in a vibratory bowl filled with abrasive media. As the parts complete the deburring cycle, they are discharged to a screened bed. The abrasive media drops through the bed and the finished parts roll into a box. Refilling the bowl with the accumulated media was a back breaking operation that required repetitious lifting of heavy buckets.
The Solution: A Model 6064 2" (51mm) Stainless Steel Line Vac was installed on the vibratory bowl. In minutes, the media was conveyed back up to the bowl through a hose without the heavy lifting.
Comment: The ability to convey the abrasive media with air was the key to success in this application. The Line Vac is easy to use since the many sizes fit standard hose and tube. In this case, the stainless steel model was the best choice since it will hold up better to the abrasive media conveyed through it.
