Super Air Wipe at Sea

I recently worked with a Chief Engineer on a large shipping boat who was having issues with water being brought in by the mooring cables. That salt water was getting into the maintenance room where the mooring cables were wound around a large spool. He wanted to remove the water from the cable before it went below deck so the extra water could just run off the deck back into the ocean.

After talking a bit we decided on a 4″ Super Air Wipe constructed of 303 stainless steel. This way the extra water would be removed and any debris the cable pulled in with it.

The Super Air Wipes provide a full 360° conical airflow that is used to blow-off, cool, clean and dry products. A Coanda profile is designed into the body of the unit to maximize entrainment of ambient air as well as give the precision angle for the air to exit from. This gives the air stream impacting the target zone a 30° angle to the surface in order to provide a substantial shear force for debris removal. This also ensures the large volume of ambient air entrained will all travel the correct direction and not become turbulent before impinging on the surface.

To meet all the tasks at hand, the Super Air Wipes are offered in two main materials of construction. Aluminum body with brass air fittings, connected with stainless steel hardware, shim and connecting hose for up to 4” (102mm). As well as 303 stainless steel body with stainless steel bolts, shim, the connecting hose for up to 4” (102mm) and fittings. The stainless-steel components give the units better corrosion resistance, higher temperature ratings, and more durability in harsh industrial environments.

The aluminum Super Air Wipe is available in 11 sizes; the stainless steel Super Air Wipe comes in 5 sizes…all from stock.

EXAIR stocks the aluminum Super Air Wipes with inner diameters from 3/8” (10 mm) for wire and cables up to 11” (279mm) for large pipes and hoses. The aluminum models have a temperature rating up to 400oF (204oC). We also stock the stainless-steel models from ½” (13mm) to 4” (102mm) inner diameters, and they have a temperature range up to 800oF (427oC). If you require different diameters or materials, we can do that as well easily.

With the creation of the Super Air Wipe, uniform cleaning, cooling, and blowing around the outside of parts is a simple task. You don’t have to worry about a variety of nozzles to target the circumference or a fabricated blow-off device that will waste air and take much time out of your day. A simple purchase of the Super Air Wipe Kit will solve the problem and keep production going. If you need help in selecting the proper size or want to know what material we would recommend for your application, contact us.

Easy clam-shell installation

To provide ease of installation, a unique clam-shell design was engineered to provide clamp over installation rather than traditional threading methods. This also permits quick changes in size when needed in the rapid product change environments.

Super Air Wipe Kit

The Super Air Wipe kits to help get the most out of the air wipes. A kit will include the Super Air Wipe, a filter, regulator and shim set. The filter will remove bulk liquids and debris from the compressed air to keep the performance optimal. The regulator is used to fine-tune the force provided by the Super Air Wipe. This helps to not over-use the amount of compressed air required for the job.

With a regulator, you can make fine adjustments to get the proper amount of air. For coarse adjustments, you can add shims to increase the airflow and force. They are easy to install on the Super Air Wipes to allow for applications to have more cooling, faster drying, and better removal for tough debris. For cleanliness and control, the Super Air Wipe Kits would be recommended for your application.

Super Air Wipe Dries Micro Tubes for Drip-Type Irrigation Systems.

Speed is everything.  A micro tube manufacturer was extruding a polyethylene tube for drip type irrigation.  This type of irrigation is very common in the desert to confine the watering near the plants in arid regions.  The plastic tubes have an 8 mm (0.315”) outer diameter with a 5.5mm (0.217”) inner diameter (reference photo below).  They were looking for ways to increase the speed of production.

Micro Tube

Their extrusion application included a water bath to cool and harden the material as it came out of the extruder.  After the bath, the tube travels directly into an inkjet marking machine.  They were using a home-made circular blowing device to remove the water after the dipping process.  When they tried to increase their line speeds, this blow-off device was not able to remove enough water from the surface.  Thus, the printing was poor, and sections would have to be scrapped.

Super Air Wipe

When they searched for a tube blow-off device, they came across the Super Air Wipe from EXAIR.  Unlike the home-made device, this engineered design blows compressed air at a 30-degree angle toward the center in a 360-degree air pattern, just like a cone.  It uses a Coanda profile to maximize the entrainment of ambient air into the compressed air stream to produce a strong force.  As a non-contact wiping device; the Super Air Wipe is very efficient and very powerful.

For this application, I recommended the model 2450 ½” Super Air Wipe Kit.  This kit includes our Super Air Wipe, a Filter, a Regulator, and a Shim Set.  With the ½” or 13mm opening, it gives ample room to allow the 8mm tube to travel through without touching.  For the rest of the kit, the Filter will remove bulk liquids and debris from the compressed air to keep the unit performing optimally and keep the tubes from getting dirty.  The Regulator is used to control the amount of force.  This helps to not over-use the amount of compressed air required for the job.  With a Regulator, you can make fine adjustments to get the proper amount of air while the shims in the Shim Set will give you coarse adjustments.  With the Regulator and Shim Set together, you can “dial” in the correct amount of force required for the different speeds.  The Super Air Wipe Kits will give you the most versatility in your system to optimize the 360-degree blow-off.

As they removed their home-made unit and attached the Super Air Wipe, they noticed some great things.  The speed of production was increased by about 10% which matched the maximum speed of the inkjet printer.  They also noticed that the Super Air Wipe is much quieter.  With a decibel rating of 77 dBA, the nearby operators are very happy with this choice.  One of the top features that they noticed was the cost savings that the Super Air Wipe gives.  Because the design uses the “free” ambient air, less compressed air is required.  This saves them a lot of money in their electric bill.

Many applications use water in the process, and it can negatively affect printing and labeling on products.  EXAIR offers a range of efficient, safe, and effective blow-off devices to remove water from the surface in a non-contact way.  For the customer above, the Super Air Wipe was their solution.  Speed is everything, but without the proper tools, it is lost.  If you have a printing or labeling application, an Application Engineer at EXAIR can help you to maximize that speed.
