No Drip Atomizing Spray Nozzles: Overview

Published on by codybiehleLeave a comment

Are you tired of your dripping nozzle leaving puddles on your equipment and making a mess? Do the liquids you use to treat or coat your materials cost you a great deal of money? EXAIR’s No Drip Atomizing Spray Nozzles have been engineered eliminate drips; these patented nozzles contain a spring mechanism that when the air pressure reaches above 30 psig the valve will open allowing the liquid to escape out.

EXAIR No Drip Air Atomizing Spray Nozzles come in three styles. Internal mix, External mix and Siphon fed. 

One of the most commonly used types of No Drip Atomizing Spray Nozzles is the Internal Mix. The Internal Mix nozzle mixes the liquid and the air inside the cap and produces the finest droplet size out of the three. Due to the fact that the liquid and air are mixed in the cap, Internal Mix nozzles are used on liquids that have a lower viscosity (less than 300 cP). This means that they are usually used on liquids such as water, water soluble/diluted lubricants, lightweight oils, or rust inhibitors.

External Mix No Drip Atomizing nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These are best when precise liquid flow is needed. External mix nozzles can be used when the liquid viscosity is above 300 cP. 

Siphon Fed No Drip Atomizing nozzles require no liquid pressure and can be use dwith gravity fed liquids or siphon liquid from a height as much as 36 in. (91cm). These can be used with liquids up to 200 cP. 

No Drip Atomizing Nozzle
The No Drip Atomizing Spray Nozzles share the same spray patterns as our line of standard atomizing spray nozzles. This means that they are available in Narrow Angle Round Pattern, Wide Angle Round Pattern, Flat Fan Pattern, Deflected Flat Fan Pattern and 360° Hollow Cone Pattern. Along with the five different spray patterns they also come in three different inlet sizes of 1/8″, 1/4″ and 1/2″ NPT.
No Drip Flat Fan Spray Nozzle
Each NPT size also comes in a variety of different sizes in the corresponding spray volume. For example, the 1/8” No Drip Internal Mix Flat Fan Nozzles have for different Nozzles with a flow rate ranging from 3.47 GPH to 28 GPH (13.2 LPH to 105.99 LPH). This gives the No Drip Internal Mix Atomizing Nozzle 36 different variations to fit your application.
No Drip Siphon Fed Round Pattern Atomizing Nozzle
The normal applications for No Drip Atomizing Spray Nozzles Include but not limited to the following:
  • Painting
  • Coating
  • Rinsing
  • Cooling
  • Quenching
  • Wetting,
  • Humidification
  • Dust Control
  • Snow Making

Or any application where drips can harm a products finish or waste valuable liquids.

Cold Gun Aircoolant System™: Overview

Published on by John BallLeave a comment
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.

EXAIR Cold Gun Promotion

Promos, Freebies, and Some Amazing Products

Like many companies, here at EXAIR we generally always have a promotional offering.  These rotate throughout the months and this month is no different.  The current offering involves the EXAIR Cold Gun Aircoolant Systems.

These systems help to reduce cutting fluid use, increase production speeds, increase tool life, and has helped more customers than I know.  One customer in particular is a maintenance worker from a welded tube manufacturer.  This facility had very little amount of downtime permitted due to the high efficiency and high volume of orders.  When a machine went down the maintenance team were in like a trauma team to determine the cause of failure and get it remedied to get the line back up and running. One of the biggest problems they would have is when they would have to dry machine a quick part to get the machine back up and running, this would either ruin tools or they would have to slow down the machining time to get the surface finish and dimensions they truly needed.  After talking with us the team ordered a Single Point Cold Gun Aircoolant System as these parts were generally smaller shafts or machine dogs.

They received the system in and sure enough a machine went down.  The crew went to work and once the part needed was found they got to work on their lathe trying to make a new piece.  The Cold Gun held itself straight to the headstock thanks to the integrated magnet and the flexible single point hose kit routed the cold air straight to the cutting point.  They didn’t have to fill up the liquid tank or setup the mist system on the lathe, they simply turned on the compressed air and let the lathe do the work.  They were able to take what had recently been around a three hour machine job with heavy wear on tooling to a two hour job, no finish pass was needed on the part, and their tools weren’t completely spent by the end of the job.

They got the part back into the machine, made adjustments, and then went to work getting the machine back into production.

Right now, if you would like to try out a Cold Gun Aircoolant System you can order before 12/31/2019 and use the link to order through our promotion in order to receive a free Dual Point Hose Kit with your qualified purchase.

The Case for the Cold Gun

Published on by Russ BowmanLeave a comment

Heat is an unavoidable by-product of any cutting or machining operation. Think about it: you’re creating friction on a piece of material with a fast-moving piece of harder material in order to forcibly separate pieces of the original material from its existing shape & size. No matter what, something’s going to get hot: the work piece, the tooling, or (almost always) both. If you don’t do something about it, your parts can become damaged, your tooling can become dull and brittle, and productivity will suffer.

There are ways to alleviate the problem…you can slow the speed of your tooling, but that’s hardly practical, and only marginally effective.  You can use liquid cooling…in fact, you may have to if the particulars of the operation require the lubrication you can only get from a cutting oil or liquid coolant.  But those can be messy, expensive, and the time you spend maintaining the coolant could certainly be spent better elsewhere…like, on machining your products!

The EXAIR Cold Gun Aircoolant System is a novel solution to these problems…heat related and otherwise:

  • The Cold Gun uses compressed air to produce a stream of clean, cold air at 50°F (28°C) below supply air temperature.
  • They use Vortex Tube technology…no moving parts to wear out.

Instant cold air flow with no moving parts!

  • Cold flow and temperature are preset to optimize cooling capability, and are non-adjustable to prevent freeze-up during use.
  • Eliminates the expense of both the purchase & disposal of cutting fluids.
  • Removes the potential for health problems associated with breathing mist & vapors, and the safety issue of slipping on a wet floor.

Cold Gun Aircoolant System selection is easy & straightforward…we offer a standard, and a High Power version to meet your specific needs.

Four systems to choose from, to meet most any need.

We also offer Single & Dual Point Hose Kits, to further meet the needs of your application.  Right now, you don’t have to decide up front…order a Cold Gun Aircoolant System with a Single Point Hose Kit before December 31, 2018, and we’ll throw in the Dual Point Hose Kit for free.

If you’d like to find out more about how Cold Gun Aircoolant Systems can improve your machining or cutting operations, give me a call.
