This video highlights the value and benefits of an engineered blow off solution. We take a homemade open pipe blowoff and replace it with an EXAIR model 1100 Super Air Nozzle. This air nozzle is then controlled through our Electronic Flow Controller, allowing for intermittent On/Off of the compressed air flow. And, these solutions are wirelessly monitored via Zigbee network using our Wireless Digital Flowmeter. Implementing these solutions results in a compressed air reduction of over 90%!!!
Full calculations along with supporting flow values (pulled from the same data shown in the video above) are shown below.
The open pipe:
The first compressed air flow values to show up on the EXAIR Logger are for the open pipe blow off. At 1 BAR operating pressure, this “solution” consumes 22.3 SCFM of compressed air. At a cost of $0.25 for every 1,000 cubic feet of compressed air, this nozzle will cost $695.76 to operate 8 hours per day, 5 days per week, 52 weeks per year.
The engineered EXAIR Super Air Nozzle
Model 1100 EXAIR Super Air Nozzles consumes 4.7 SCFM at an operating pressure of 1 BAR – a reduction of 79% compared to the open pipe. These savings prove out in terms of operating cost as well – $146.64 per year, compared to $695.76.
The engineered EXAIR Super Air Nozzle with Electronic Flow Control (EFC)
By controlling the “ON” time for this application with an EFC, we are only blowing for 32% of the time for each minute of operation which changes the required compressed air flow from 4.7 SCFM to a peak value of 1.5 SCFM. This control saves an additional 68% of compressed air flow. And, these savings are compounded by eliminating the need for constant compressed air flow. Total annual operating cost for the EXAIR 1100 Super Air Nozzle with Electronic Flow Control is just $46.80.
