EXAIR Line Vacs™: Air Operated Conveyor Promo

EXAIR Line Vacs

As an Application Engineer, I get the pleasure to speak to many companies about finding a simple, long-lasting, powerful and quiet type of transfer system.  Companies have operators that climb steps to dump bags of material into hoppers above.  This can be dangerous and is not ergonomic.  Other applications would include a compact way to remove scrap from a process; or budgetary constraints to convey material from point A to point B.  If your company has to tackle any of these issues, EXAIR can help you.  We manufacture Air Operated Conveyors that do not have any moving parts, very compact in design, and have a high throughput capacity.  They can attach easily to standard hoses, pipes, or sanitary flanges.   These inexpensive conveyors are designed to make conveyance safer and ergonomically better for your staff.  EXAIR calls this product line, Line Vacs™

Line Vacs can convey many things.

Line Vacs use a small amount of compressed air to generate a vacuum by a Venturi effect.  The unique design generates a high velocity to create a powerful vacuum on one side.  Once the product reaches the throat area of the Line Vac, the compressed air will carry the product the rest of the way.  We can reach horizontal distances up to 100 feet (30 meters) and vertical heights up to 20 feet (6 meters).  EXAIR manufactures a variety of Line Vacs in different sizes, styles, and materials.  Here is an overview of the Line Vacs that EXAIR offers.

Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

Line Vacs:  Our standard Line Vac is the most versatile product in this family.  We have two types of connections, slip-on ends for hose connections and threaded ends for pipe connection.  EXAIR can also mix the connection types on each end.  They range in diameters from 3/8” (10mm) up to 5” (127mm).  We manufacture the Line Vacs in aluminum, 303SS, and 316SS; but don’t let that deter you from asking for special types of materials.  We have a high temperature version that can withstand temperatures up to 900oF (482oC).  These Line Vacs work great in applications for loading plastic pellets in hoppers, discarding scrap pieces, trim removal, and transferring material.  If an operator has to place a bag of dry material on his shoulder to climb stairs, a Line Vac would be a much better alternative.

Heavy Duty Line Vac Family

Heavy Duty Line Vacs:  They are made from a hardened alloy steel for abrasion resistance.  The generators inside these Line Vacs are more powerful than the standard models; so, that they can convey heavier materials at higher conveyance rates.  They can reach rates as high as 40 lbs./min. (18.2 Kg/min) of material.  With the hardened alloy construction, they are great for sand blasting materials, ceramic, glass and steel shot.  They are manufactured with inlet and outlet connections for ship-on hoses or threaded pipes.  EXAIR stocks the Heavy Duty Line Vacs in the range from ¾” (19mm) to 3” (76mm) for both hose and NPT connections.  These Line Vacs are our most powerful design with great wear resistance.      

Light Duty Line Vacs

Light Duty Line Vacs:  On the other end of the Line-Vac spectrum, EXAIR created the Light Duty Line Vac.   They use much less compressed air than the other Line Vacs which is great for moving lightweight materials over short distances.  They can also be used for removing smoke and fumes from a work area.  The Light Duty Line Vac ranges from ¾” (19mm) up to 6” (152mm) diameter for slip-on hose connections.  This two-piece design provides an effective way of moving material at a lower cost.  It can be used in applications like hopper loading, fiber tensioning, filling operations, and smoke removal.   For moving material within a short distance, the Light Duty Line Vac could be the proper product to use. 

Sanitary Flange Line Vacs

Sanitary Flange Line Vacs:  Our latest engineering design within the Line Vac family is the Sanitary Flange Line Vacs.  They can convert pipes into a useful conveyor for bulk material and waste removal.  They use an ISO2852 flange for easy disassembly and cleaning to reduce bacterial entrapment.  They ae made from 316 stainless steel material for superior corrosion resistance.  They come in four different sizes to fit the sanitary flanges from 1 ½” up to a 3” flange.  For sensitive applications where cleanliness is a major requirement, the Sanitary Flange Line Vac are manufactured for these conditions. 

With all of the EXAIR Line Vacs above, they can be sold as kits.  A kit will include a filter, regulator and a bracket.  (Bracket are not sold with all types and sizes.)  The filter will help keep the Line Vac clean as well as the product that it being conveyed.  The regulator is a great tool to vary the conveyance rates for better control.  The bracket helps to mount the Line Vac to a sturdy base for support.      

If you need to convey solid materials in a quick and easy way, an EXAIR Line Vac could be a solution for you.  We have them in a variety of formats to match your application.  They are compact, quiet, and simple to use without any moving parts.  As compared to a conveying system which are bulky and rigid, the Line Vacs are flexible and inexpensive.  Ergonomically, they can save the back-wrenching labor of picking up bags, climbing stairs, and dumping material into hoppers.  For our U.S. and Canadian customers, we are running a promotional ad.  You will receive a 2” Flat Super Air Nozzle, a $75.00 value, for free from now until the end of October 2021 with a qualified purchase online.  If you would like to discuss your conveying application further, please contact an Application Engineer at EXAIR.  We may have the perfect solution for you.

Spot Cooling

A new solution to an old problem. Heat build up on dry machining operations reduces tool life and machining rates. The Cold Gun Aircoolant System produces a stream of clean, cold air at 50°F (28°C) below supply air temperature. Operation is quiet and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolants cannot be used.

The Cold Gun is also an alternative to expensive mist systems. It eliminates the costs associated with the purchase and disposal of cutting fluids and worker related health problems from breathing airborne coolants or slipping on wet shop floors.

The standard Cold Gun and High Power Cold Gun incorporate a vortex tube to convert an ordinary supply of compressed air (1) into two low pressure streams, one hot and one cold. The Cold Gun’s hot airstream is muffled and discharged through the hot air exhaust (2). The cold air (3) is muffled and discharged through the flexible hose (4), which directs it to the point of use. Easy mounting and portability are provided through the use of an attached magnetic base (5).

Applications include tool sharpening, drill and cutter grinding, drilling, band saw cooling, plastic machining and setting adhesives. 

EXAIR offers two types, the Cold Gun and the High Power Cold Gun.  The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity.  They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle.  All systems come with a magnetic base and a filter separator.  The magnetic base makes this device simple to attach to your machine and start using.

The Heavy Duty Line Vac™ moves CO2 Cartridges

Threaded Heavy Duty Family

In trying to cut over-all costs, companies are reviewing process flows throughout their plant.  A CO2 cartridge manufacturer was following that same strategy.  They wanted to move the silk-screening process that marked the outside of the cartridges to a different location.  Currently, the operators would have to pick up bins to move them about 50 feet (15 meters) to the packaging area.  They currently were using blower-type vacuum systems in other parts of their process to move the cartridges through different stages.  But, the bulkiness and noise level of the blower system made them have to find an alternative way; so, they contacted EXAIR.

For their process, they would start with a steel cap.  The metal caps would run through a series of different forms where round punches would “redraw” the metal into a final diameter and thickness.  Once it is finished through this process, it would look like a test tube.  The metal tubes would have the ends heated and pressed with a set of different dies to create the “neck” region.  The “neck” section would be cut and lathe to make a sealing edge.  The cylinders would then go through a washing and drying system to clean.  Once dried, they would travel to the filling station where the cylinders would be partly filled with liquid CO2, and then capped.  The bare steel cylinders would move through a zinc-coating process for protection and appearance.  The filled cartridges would then be inspected by quality control prior to screen printing on the outer diameter.  The finished CO2 cartridges had an outer diameter of ¾” (19mm) (reference photo below).  Once they are printed, the shipping staff would carry them to their department for packing.

The process flow change for this company was to move the silk-screening process about 50 feet (15 meters) from the current position.  With an EXAIR Air Operated Conveyor or Line Vac™, the QC department can transfer the cartridges to the screen printer near the packaging department.  This would stop the needless handling of the filled bins between the printing station and the packaging station.  Not only did this speed up packaging, but it also ergonomically helped the operators from lifting and carrying.

Heavy Duty Line Vac Kit

For the material, distance, and size; I recommended the model 152125 1 ¼” Heavy Duty Line Vac Kit.  This Line Vac is made from a hardened alloy material which makes them resistant to abrasion and wear.  The throat diameter has a clearance of 1” (25mm) which is enough to carry the ¾” (19mm) diameter cartridges.  With a kit, it will also include a filter, regulator and a bracket.  The filter will help keep the Line Vac and the cylinders clean.  The regulator will allow for flexibility in conveyance rates, distances, and speeds.  The bracket helps to mount the Line Vac to a sturdy base for support.    With the small footprint and compact design, it was easy to set up and use as a simple conveyor.

After installation, the Production Manager was amazed by the simplicity of the design and the ease of operation.  He could also reduce maintenance cost without having to change intake filters, check bearings, monitor electrical controls, and replace any failed motors within the blower-type system.  The EXAIR Line Vacs do not have any moving parts to wear; so, they are reliable and long-lasting.  Overall, as compared to the blower-type systems; the cost, set-up, and operation were greatly improved with the EXAIR Line Vac.  They were so happy in meeting the criteria above; the Production Manager mentioned that he would be replacing their existing blower systems when they fail.  And as mentioned above with all the transfers to the different stations, there would be many spots for the EXAIR Line Vac to be used.

If you need to convey materials like cartridges, steel shot or abrasive products, the Heavy Duty Line Vac could be a blessing for you.  Not only can they transfer material safely and quickly, but they also will ergonomically help in saving the backs and knees of your operators.  How can this get any better?  Until the end of October 2020, we are running a promotional ad for our U.S. and Canadian customers.  You will receive a 2” Flat Super Air Nozzle, a $72.00 value, free with qualified purchases online.  If you would like to discuss any of your conveying application, please contact an Application Engineer at EXAIR.  We may have a solution for you.

Cold Gun Aircoolant System™: Overview

EXAIR Cold Gun Promotion

Many machining companies like to use coolant to flood their parts for drilling and milling operations.  But what if there was an alternative way?  EXAIR has an interesting technique by using cold air instead of coolant.  This would help save time by eliminating cleaning and drying of parts as well as reducing coolant waste.  EXAIR calls this product our Cold Gun Aircoolant System™.

How the Cold Gun Works

The Cold Gun Aircoolant System uses a Vortex Tube to produce a cold air stream at 50oF (28oC) below supply air temperature.  Heat is one of the major causes for dulling and premature failures for tools, and by blowing cold air, it will reduce the heat buildup in tools while also removing the chips from the surface.  The EXAIR Cold Guns are very compact, portable, and easy to use.  Just attach compressed air to the unit, and it will produce cold air.  Since they do not have any moving parts, Freon, or electricity to operate, it is maintenance-free and long-lasting.  And, EXAIR offers a 5 year “Built To Last” warranty against defects in workmanship and materials.  These systems will extend tool life, improve tolerance control, and increase production rates by replacing coolant during milling, cutting, and drilling operations.

The benefits of using the Cold Gun Aircoolant System extends beyond reducing tool wear, finishing with dry parts, and surface smearing.  It can be used in applications where liquid coolant cannot be used.  This would include wood products, MDF, and plastics.  As insulators, cutting tools will get extremely hot as the material will not remove any heat like with metal chips.  Thus, machining can soften, gall, or burn the surface of the material; allowing only slow speeds for operations.  The cold air from the Cold Gun can keep the tools sharp and the materials hard and firm.  With plastic materials, this is very beneficial as it will keep the plastic rigid for tight tolerance machining.  If burnishing or scoring is occurring, the Cold Gun Aircoolant Systems can help to improve the surface finish of your product.  Other applications would include surface grinders, laser cutters, hot melt setting, and band saws.  The Cold Gun Aircoolant Systems are a low-cost solution that can do a lot of great things to improve processes.

Cold Gun Aircoolant Systems

EXAIR offers two types, the Cold Gun and the High Power Cold Gun.  The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity.  They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle.  All systems come with a magnetic base and a filter separator.  The magnetic base makes this device simple to attach to your machine and start using.  The four models that EXAIR stocks are in the photo above.

EXAIR is running a promotional offer on the Cold Gun Aircoolant Systems.  From now until the end of yr2019; if you buy a Single Point Cold Gun System or a Single Point High Power Cold Gun System; model W5215 and model W5230 respectively, we will include a free model 5902 Dual Point Hose Kit, a $39.00 value, with your system.  And as always, EXAIR offers a 30-day unconditional guarantee for our customers in the U.S. and Canada to try them out.  If you have an application that you believe would be better served with an EXAIR Cold Gun Aircoolant System™, contact an Application Engineer.  And take advantage of our promotional offering by receiving a FREE Dual Point Hose Kit.
