Small, Precise Blowoff at Your Fingertips

For many blowoff applications, stronger isn’t necessarily better.  For applications and processes where a light, but effective blast of air is needed for cleaning and drying, the VariBlast Compact Safety Air Gun with the Atto, Pico, or Nano nozzle fits the bill. The smallest of the EXAIR engineered Super Air Nozzle family, the Atto, Pico, and Nano have been designed to provide the smallest, most precise blowoff possible. The focused airflow pattern allows for very accurate control and placement of the air stream.  The nozzles are available in both Type 316 Stainless Steel and PEEK plastic (useful for harsh environments, and is non-marring)

The new VariBlast Compact Safety Air Gun is a great choice for putting the power and performance of the nozzle into a small and lightweight air gun. Designed with a variable flow trigger, the airflow can be throttled from a whisper to full force, simply by varying the trigger pull distance.

The Atto, Pico, and Nano nozzles use very little compressed air and are extremely quiet, easily meeting OSHA Standard 29 CFR 1910.95(a) for Noise Exposure.  The design incorporates engineered solutions for safety and can be supplied with higher pressure compressed air and meet OSHA Standard 29 CFR 1910.242(b), relating to dead end pressure requirements.

The table below provides performance data, including the compressed air consumption, force, and sound level for the various configurations.

Note that the VariBlast air guns can be had with extensions from 6″ to 72″ and chip shields to meet the performance and safety needs of any application.

The Atto, Pico and Nano Nozzles can also be configured to work with the Soft Grip style of Safety Air Gun.  Consult an Application Engineer for assistance in choosing.

If you have any questions about the Atto, Pico, or Nano nozzles, the VariBlast Compact Safety Air Gun, or any EXAIR compressed air product, feel free to contact EXAIR and myself or one of our Application Engineers can help you determine the best solution.

PEEK Super Air Nozzles Resist Corrosion; Won’t Scratch Sensitive Surfaces

Because they might be needed in some pretty aggressive environments, EXAIR offers many of our Intelligent Compressed Air Products in a variety of materials. One particular material of construction, however, has two distinct benefits. PEEK (Polyether Ether Ketone, for those of us who ruined the grading curve in CHEM102) plastic offers not only superior chemical corrosion resistance; it’s also non-marring. Since EXAIR introduced the first PEEK Super Air Nozzle in 2005, they’ve been specified all over the world; sometimes for their corrosion resistance; other times so they won’t mar or scratch sensitive surfaces…and every once in a while, for both.

I recently had the pleasure of discussing blow off applications with the production manager of a large anodizing & plating company. The chemicals used in these processes are extremely corrosive, and the equipment used in those areas has to be made of something that’ll handle it. PEEK plastic is just such a material. Also, once they’ve treated their customers’ parts, they need to handle them with care…they’re getting paid a premium to provide nice, shiny parts with a perfect finish. When they’re blowing them off, they need to use something that won’t scratch up the surface if the operator makes incidental contact with the blow off tip. Again, PEEK plastic is just such a material.  Since their existing blow offs were fitted to 1/8 NPT connections, they chose the Model 1102-PEEK Mini Super Air Nozzle.

EXAIR’s PEEK Super Air Nozzles can be mounted in place or on a Safety Air Gun, depending on your needs.

Corrosion resistant and non-marring…EXAIR offers our PEEK Super Air Nozzles in six sizes, from the Atto (M4x0.5 threads; 2.5 SCFM; 2 oz force applied) to our High Force Model 1104-PEEK (3/8 NPT threads; 35 SCFM; 1.9 lbs force applied) for an incredibly diverse range of applications.

If you’d like to discuss what material(s) of construction your application(s) require, give me a call.

Go OSHA Safe & Save Money in the Process

Another customer has contacted EXAIR and taken advantage of our FREE Efficiency Lab.  This customer has approximately 150 homemade magnetic blow offs throughout their facility.  They are being used to help move and push paper down the lines.

This unit was taken into the lab and put through the paces. The first being flow; The drilled hole in the pipe plug measured out to be a .061″ diameter hole.  The customers operating pressure for these units is 50 PSIG, so all testing was performed at 50 PSI at the unit.  The unit was flowing 3.46 SCFM per nozzle.   We then tested the sound level, at a distance of 3′ the unit measured 77.5 dBA, then force measured  3.2 oz at 12″ away from the homemade blow off.

Because the homemade blow off was a 1/8″ MNPT pipe plug it’s extremely easy to replace the unit with one of our Atto Super Air Nozzles.  The Atto Super Air Nozzle is a good fit for this application, even with a slightly lower force value, since we have determined the application can be successful at lower force values. The Atto Super Air Nozzle will also produce OSHA compliance for this blow off process. For this application the Atto Super Air Nozzle was tested at 50 PSIG inlet pressure and consumed 1.89 SCFM, created a 63.5 dBA noise level, along with gave 1.6 oz. of force 12″ away.

This calculates to saving 1.57 SCFM per nozzle, reducing the ambient noise level by 14 dBA, and still being able to get the job done.  When you calculate the savings for all 150 nozzles being operated at once the customer will save $3.53 per hour of operation.  Considering these nozzles run whenever  product is present that means the customer will save $28.26 per 8 hour day.

On top of the cost savings the customer gains the safety of the Atto Super Air Nozzle.  Their original blowoff device does not meet or exceed the OSHA standard for 30 PSI dead-end pressure.  Because the piece has a single hole the risk of an air embolism is there.  With the EXAIR Pico Super Air Nozzle we meet or exceed the OSHA standard for dead-end pressure to help keep the operators safe and in a quieter environment.

If you would like to take advantage of the EXAIR Efficiency Lab feel free to fill out the form and then send in your sample.  We’ll get it tested and give you a full report on how we can help.
