EXAIR’s Efficiency Lab is now the “award-winning Efficiency Lab”. Thank you to Environmental Protection Magazine for recognizing the value and importance of this EXAIR service.
I have blogged about this many times and we continue to help customers by using our free Efficiency Lab service that EXAIR provides to customers throughout the USA. The EXAIR Efficiency Lab allows customers to send in their existing blow off device and we will test it for compressed air consumption, sound level, and force. Ideally we try to take these measurements at the same operating pressure that is being supplied in the field so that we can compare it to an EXAIR product and offer the customer the best solution, the safest solution, and an engineered solution capable of saving them money through air savings and effectiveness.
Here is a recent example of a product sent in by a customer concerned with compressed air consumption and safety of their people. The hose they sent in was actually designed to be used with liquid coolants and was a very large consumer of compressed air.
The hose shown above was being used at 40 psig inlet pressure. The device is not OSHA compliant for dead end pressure, nor does it meet or exceed the OSHA standard for allowable noise level exposure. The hose was utilizing 84.64 SCFM of compressed air and was giving off 100.1 dBA of sound.
As seen in the chart above, an employee is only permitted to work in the surrounding area for 2 hours a day when exposed to this noise level. The amount of force that the nozzle gave off was far more than what was needed to blow chips and fines off the part. The EXAIR solution was a model 1002-9230 – Safety air Nozzle w/ 30″ Stay Set Hose.
The EXAIR products were operated at line pressure of 80 psig which means they utilized 17 SCFM of compressed air and gave off a sound level of 80 dBA. On top of saving over 67 SCFM per nozzle and reducing the noise level to below OSHA standard, the EXAIR engineered solution also meets or exceeds the OSHA standard for 30 psig dead end pressure. In total this customer has replaced 8 of these inefficient lines and is saving 541 SCFM of compressed air each time they activate the part blowoff.
If you would like to find out more about the EXAIR Efficiency Lab, contact an Application Engineer.
We look forward to testing your blow off and being able to recommend a safe, efficient, engineered solution.
