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.
