EXAIR’s Huge Variety of Air Nozzles is Like an Equalizer for your Application

MCS 3035 Final

Many of us are familiar with what an equalizer (EQ) looks like and what it does. Unfortunately, sometimes they get a bad rap from so-called audiophiles, which in my opinion are defined individuals who spent so much money on their equipment they can’t afford to buy any music to play!  Typically, they insist that tone controls must be set to flat because the sound recording engineers mastering the music have already equalized the recording to perfection and if you need to attenuate or cut certain frequencies it is an indicator of poor-quality equipment, and that is simply is not true!

Let’s consider some of the reasons why an equalizer makes sense and, in my opinion, an absolute necessity. The objects and materials in the room will change the sound reproduction characteristics of any speaker system.  If you have large floor standing speakers positioned in the corners of the room, sitting directly on wood floors the speakers are now “acoustically coupled” with the floor and the walls.   On the other hand, if you move the speakers away from the wall and/or place them on spikes or stands (isolating them for the floor) you would have “acoustically de-coupled” the speakers from the walls and floor, which will reduce the bass or low-frequency loudness. This all affects the perceived loudness and/or quality of the music we want to listen too.

This is where the graphic equalizer shines, no need to move the speakers around or use speaker stands or spikes.  An equalizer will allow you to increase or decrease the loudness of multiple frequencies.  You can completely customize your sound to suit your tastes, overcome issues with your listening room acoustics, the speakers you are listening with or even anomalies with the music recording.

Like adjusting an equalizer to suit your room acoustics, speaker size and/or speaker frequency response, EXAIR understands that the need for many different options gives you the necessary adjustments for a successful application.  A few sizes of Air Nozzle, Air Jet or High Force Air Nozzles will not solve every application with the highest efficiency or effectiveness.  EXAIR’s air nozzle variety allows you to produce maximum effectiveness based upon the air pressure and air volume you have available.  Whether you need a strong blast or a gentle breeze, if you have tricky mounting positions or remote applications, EXAIR has the largest selection to choose from and solve your production problem.

We clearly state compressed air volume requirements in SCFM (Standard Cubic Feet per Minute) at a given operating pressure in PSI (Pounds per Square Inch), force at 12” from the compressed air outlet and the sound loudness in dBA at 3′ from the nozzle. These details provide the starting point for selecting the best air nozzle.

When you are looking for expert advice on safe, quiet, efficient, and engineered point of use compressed air products give us a call.   We would enjoy hearing from you!

Safety Air Guns: Chip Shields, Extensions, and More

Over the last several weeks, you may have read blog posts regarding the EXAIR Safety Air Guns.  You can find the blogs here, here and here. We are also in the midst of a Safety Air Gun Promotion, please click HERE for more details on how you can get a free 1″ Flat Super Air Nozzle. Today, I want to review a few available options for the Safety Air Guns.

Protect Workers From Flying Debris! – Chip Shields are durable polycarbonate shields that protect the operator from flying debris often seen when blowing off chips from machined parts. They are also useful to prevent coolant from splashing back, creating a mess during drying processes.

The Chip Shields are available for EXAIR’s VariBlast, Soft Grip, and Heavy Duty Safety Air Guns. The Chip Shield can be used on Safety Air Guns with or without an aluminum extension. They may be purchased as part of a new air gun system, or retrofitted as a Chip Shield Kit.  Consult an Application Engineer for selection assistance.

 

If you have a blow-off process where the air is to be directed at a distance away from the operator, or into a hard to reach location an extension is the solution. Available in lengths from 6″ (152mm) to 72″ (1829mm), with sizes as shown below, a length to meet most any requirement can be found. To add an extension to an air gun, simply add -xx to the current part number.

Safety Air Guns – Using Engineered Air Nozzles For High Performance

Inexpensive air guns can be picked up just about anywhere, and you generally get what you pay for. Most will be very noisy and waste lots of compressed air.  And many will be unsafe, violating two of OSHA’s standards put in place to protect worker safety. The first is Standard 29 CFR 1910.95(a) which sets limits to the maximum noise exposure, and the second is Standard 29 CFR 1910.242(b) which says that the nozzle cannot be dead-ended, or exceed a 30 PSIG pressure limit.

These guns may seem like a perfect fit for a handheld blowoff application. The truth is, the cost saved up front will easily be paid throughout the cost of ownership.  This is due to the lack of an engineered nozzle which meets and exceeds the OSHA standards mentioned above.   The “cheap” guns often have a cross drilled hole to meet or exceed the OSHA standard for dead-end pressure. While this may be true, it causes a large wind sheer which escalates noise levels to well over the allowable noise level exposure set by OSHA.  These tips sometimes offer large force outputs because they are equivalent to an open pipe.  We have publicized numerous times about how an open pipe blow off does not permit pressure to be utilized all the way to the point of blowoff, and is also a waste of energy.

In order to determine how much compressed air your current blow guns utilize, the level of noise they product, and the sound level they produce, consider taking advantage of the EXAIR Efficiency Lab.  The Efficiency Lab is a free service that you can read more about here.

An EXAIR Safety Air Gun is engineered and designed to comply both of the OSHA standards mentioned above, ensuring safe operation for company personnel.  On top of the safety designed into the guns, we also ensure all of our guns are efficient by offering only engineered nozzles on them.

EXAIR offers (4) types of Safety Air Guns – the VariBlast, the Soft Grip, the Heavy Duty, and the Super Blast.  Each type of Safety Air Gun is offered with a plethora of nozzles, as well as varying length extensions, with or without the Chip Shield.

EXAIR Safety Air Gun Promotion

From August 1st to September 30th, 2018, EXAIR will be giving away a 1” Flat Super Air Nozzle with the purchase of any promotional VariBlast, Soft Grip, or Heavy Duty Safety Air Gun.  EXAIR is stressing the importance of safety in the workplace with the EXAIR Safety Air Guns as well as the versatility of the different types of EXAIR Super Air Nozzles.

SAGpromoAD_500xsq

This promotional item, the model 1126 1″ Flat Super Air Nozzle, has a patented shim to blow a 1” wide stream of air to clean surfaces quickly and efficiently and is a $45.00 USD value. For more details on the Promotion, click on the photo/link above. For more information about the Flat Super Air Nozzles, click HERE.

Inexpensive air guns can be purchased just about anywhere- online, via catalogs, and through industrial supply companies. Typical quality is less than ideal – broken triggers, leaky valves – a short lifespan in an industrial setting are merely a few of the issues observed.  Most are loud and inefficient – they just blow large amounts of compressed air, and at noise levels that violate OSHA requirements.  Some may even generate dangerous dead end pressure situations that that can result in serious or fatal injuries if blocked.

EXAIR’s Safety Air Guns have been engineered and designed to eliminate these issues. They are durable for use in industrial situations and comfortable to use for extended periods of time.  With an EXAIR engineered air nozzle, each model provides top performance by entraining large volumes of surrounding air into the air-stream. Operation is assured to be safe along with low compressed air consumption and noise levels.  Due to the design, the airflow that exits the nozzle cannot be blocked, as required by OSHA Standard 29 CPR 1910.242(b).

Safety Air Guns
The EXAIR VariBlast, Soft Grip and Heavy Duty Safety Air Guns

The VariBlast style of safety air gun offers variable force based on the range of trigger pull. Force can be varies, form a light breeze, to full force maximum output. This cast aluminum air gun can be fitted with any of the EXAIR 1/8 NPT engineered air nozzles.

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)

sgsagpromo

The Super Air Knife is the latest generation of the EXAIR engineered air knives with dramatically reduced compressed air usage and noise compared to other types of blowoffs.  The Super Air Knife is truly a more efficient tool for cleaning, drying or cooling parts, webs, or conveyors.  The air flow is a uniform sheet of laminar air across the entire length with a hard-hitting force.

Replacing a noisy blowoff with a Super Air Knife results is a significant reduction in sound.  Operation at a high pressure of 80 PSIG (5.5 Bar) leads to a sound level of just 69 dBA for most applications. Air amplification ratios (entrained air to compressed air) of 40:1 is produced. It also meets OSHA maximum dead-end pressure and noise requirements, for safe operation in the vicinity of plant personnel.

Typical applications for use include-

  • Post wash part drying
  • Sheet cleaning in strip mills
  • Conveyor cleaning
  • Part or component cooling
  • Web drying or cleaning
  • Environmental separation (air curtain)
  • Pre-paint blowoff and cleaning
  • Bag opening/filling operations
  • Scrap removal on converting operations
