Safe blow guns for dry and clean blowing with compressed air
Blow guns are used in many industries and beyond (e.g. car washes) to clean and dry all kinds of products. It is common knowledge that this involves various occupational risks. Every year, thousands of industrial accidents occur when cleaning machines, workplaces and workpieces with compressed air.
With EXAIR blow guns and nozzles and DynaVariacor rotary joints, some of these risks can be reduced:
Hearing damage
Noise is harmful to hearing if the daily dose of 80 dB(A) is exceeded. For a worker, the daily dose is determined using two averages:
- The average noise level to which he or she is exposed per day;
- The average duration of this exposure in a week with 8-hour working days.
When blowing products dry and clean using compressed air with regular blow guns and blow nozzles, a noise level of 90 - 110 dB(A) is easily produced.
By carefully matching the EXAIR blow gun or nozzle to the application, the noise level can be reduced to well below 80 dB(A)!
A second additional advantage is that EXAIR blow nozzles are many times more effective than conventional blow nozzles. This not only results in a quieter working environment, but also reduces compressed air consumption.
Eye injury
Eye injury is one of the most common injuries when blowing products clean with blow guns. Small particles can be blown into the air. When a particle enters the eye, they often penetrate deeply into the eye. These particles are difficult to remove and only by medical specialists. Permanent eye damage or even complete blindness can result. Wearing eye protection is a must and applying a tension shield can help reduce eye injuries in many cases.
Serious internal injury
In the US, the Occupational Safety and Health Administration (OSHA) has set a standard for the safe use of blow guns. Many (cheap) blow guns are fitted with a nozzle that allows the possibility of completely closing off the outlet. If this is done on the skin and the static pressure exceeds 2 Bar, there is a risk of the compressed air penetrating the skin and entering the bloodstream. Air in the bloodstream is also known as an embolism, and can cause serious injury, even fatal. All EXAIR nozzles are designed so that they can never be completely blocked.
Joint complaints
When using pneumatic tools and blow guns, the wrist and elbow weights in particular can be subjected to forces. The weight of the air hose, tight spaces and performing the same movement repeatedly can lead to joint complaints. DynaVariacor swivel joints can help reduce these complaints. The patented design offers full freedom of movement between the blow gun and the air hose.
