EXAIR’s Line Vacs are a great option for replacing your ‘bucket and ladder‘ operation. There are many factors that need to be considered when selecting the best option – how far are you looking to convey? What conveyance rate are you looking to achieve? Is your material abrasive? – to name a few.
Using data we have gathered from our controlled in-house testing, we can almost always recommend a stock-option Line Vac that will meet your application’s needs.

There are some instances however, when your needs will be better met with a custom solution. In this blog I wanted to highlight a few custom Line Vacs that we have produced for customers in the past:

This Special Mini Line Vac was designed with barbed fittings (unlike the hose or threaded fittings) for easier installation for a manufacturer of integrated circuit chips. It was used to remove microscopic debris. The small body and high vacuum flow made it a perfect fit for the confined working space.

This 1 ½” Flanged Line Vac was designed using PVDF to provide a superior chemical resistance. In this case, the unit was going to be exposed to a chloride wash which would corrode all versions of steel, including stainless steel. The QF Flanges were also added to provide easy disassembly when the Line Vac was scheduled for cleaning.

This Special Flanged Line Vac was used to convey a measured granulated material into a pouch. The funnel side was loaded with the pre-measured material and pushed into a mesh pouch when the air was activated.

This Special Flanged Refumigation Line Vac was used to retrofit existing machinery to remove acidic vapors resulting from surface etching of a silicon wafer. Where this would typically be a nice fit for a Stainless Steel Air Amplifier, the existing exhaust piping was lengthy with many bends that would have caused back pressure on any Air Amplifiers. In this case, they needed additional force from the Line Vac to overcome this downstream resistance.

This Special Threaded 1″ Aluminum Line Vac was used to remove fumes from a welding application, and needed to be threaded into a flame retardant filter bag. The custom threads allowed them to screw the filter bag directly onto the line vac with the added insurance of a threaded connection to prevent sparks from escaping the bag.

As you can see, we have many examples of non-stock Line Vacs (as well as special items from other product lines). If you have an application you would like to discuss, feel free to give me a call!
