$2,045.22 Annual Air Savings On A Flat Panel Display Blowoff
A flat panel display manufacturer runs 3 shifts. It takes a 40 second cycle to produce one fully assembled display. Prior to packaging, they use EXAIR’s 12” (305mm) Super Ion Air Knife at 40 PSIG to blow across the display to remove any static electricity, dust, debris and plastic flash from the panel surface. The air ran constantly. The displays are under the airflow only 10 seconds. 30 seconds pass until the next display is in position. They manufacture 675 displays per shift (7.5 hrs.) for a total of 2,025 displays manufactured per day.
Old Method
EXAIR’s 12” (305mm) Super Ion Air Knife was supplied at 40 PSIG to clean the displays.
At 40 PSIG, EXAIR’s 12” (305mm) Super Ion Air Knife consumes 20.4 SCFM (577 SLPM)
Non-stop blowing of 1,440 minutes (24 hours) per day X 20.4 SCFM = 29,376 SCF (831,341 SL) air usage per day.Before the EFC installation:
Most large plants know their air cost. If the actual cost is unknown, $0.25 per 1,000 SCF (28,329 SL) is reasonable.
29,376 SCF/1,000= 29.38 X $.25 = $7.34 air cost per day.
New MethodThe EFC was installed to shut off the compressed air for 30 seconds of the 40 second cycle. (Turns air off for 75% of the cycle.)
With the EFC installed:
The EFC shut the air off during the three 30 minute shift changes. Upon sensing the display, the timer turned on the compressed air for only 10 seconds of each 40 second cycle (25% of the time).
1,440 minutes per day - 90 minutes between shifts =
1,350 minutes of operation per day.
1,350 minutes x 25% = 337.5 minutes of air per day
337.5 minutes x 20.4 SCFM = 6,885 SCF (194,846 SL) air usage per day
6,885 SCF/1,000 = 6.89 x $.25 = $1.72 air cost per day
$7.34 (old air cost) - $1.72 (new air cost) =
$5.62 savings per day x 7 days a week =
$39.33 savings per week x 52 weeks a year =
$2,045.22 savings per year.The timer was set to the “interval” setting when detecting the flat panel displays. The sensor was mounted 1” (25mm) prior to the Super Ion Air Knife blowoff station. When it detected the flat panel, it turned the air on immediately and started the 10 second timing sequence for closing the valve (shutting the air off). In the event the conveyor stopped, the air would no longer cycle on again until the next flat panel was detected.
$5,012.28 Annual Air Savings For Pre-Paint Bumper Cleaning
A manufacturer of car bumpers installed a 60” (1524mm) Super Ion Air Knife in the down draft cleaning area prior to their paint booth. The bumpers enter that area in the same orientation as they would when mounted to the automobile, moving at 10’ (3m) per minute with a 12” (305mm) space between bumpers. The bumpers are under the blow off for 10 seconds. 6 seconds pass with no bumper in the ionized airflow. The operation runs around the clock with three shifts.
Old Method
EXAIR’s 60” (1524mm) Super Ion Air Knife was supplied at 40 PSIG to clean the bumper.
At 40 PSIG, EXAIR’s 60” (1524mm) Super Ion Air Knife consumes 102 SCFM (2,887 SLPM).
Non-stop blowing of 1,440 minutes (24 hours) per day x 102 SCFM = 146,880 SCF (4,156,704 SL) air usage per day.
Before the EFC installation:
Most large plants know their air cost. If the actual cost is unknown, $0.25 per 1,000 SCF (28,329 SL) is reasonable.
146,880 SCF/1,000=146.88 x $.25 = $36.72 air cost per day
New Method
The EFC was installed to shut off the compressed air for the 6 seconds where no bumper was present - an on cycle reduction of 37.5%.
1,440 minutes x 37.5% = 540 minutes of off time per dayWith the EFC installed:
146,880 SCF X 62.5% on cycle = 91,800 SCF/1,000 = 91.8 x $.25 =
$22.95 air cost per day
$36.72 (old air cost) - $22.95 (new air cost) =
$13.77 savings per day x 7 days per week =
$96.39 savings per week x 52 weeks per year =
$5,012.28 savings per year.
The timer was set to the “interval” setting when detecting the bumpers. The sensor was mounted next to the Super Ion Air Knives. When it detected a bumper, it turned the air on immediately and started the 10 second timing sequence for closing the valve (shutting the air off). In the event the conveyor stopped, the air would no longer cycle on again until the next bumper was detected (the conveyor was turned on again).
$3,393 Annual Air Savings On A Tank Blowoff Operation
A company that refurbishes large pressurized tanks runs the tanks through an oven to burn off the old paint. Only one tank at a time can be processed. The single tank is loaded onto the conveyor and the system is turned on. The conveyor starts to move and the series of Super Air Knives used for blowoff at the exit of the oven is turned on. At 80 PSIG, the four Super Air Knives consume 348 SCFM (9,848 SLPM). The blowoff runs for 5 minutes waiting for the first tank to make it through the oven and approach the airflow (wastes 1,740 SCF/49,242 SLof air). It takes one minute to pass through the airstream. Once the blowoff is complete, the conveyor stops and the air is shutoff. The stripped tank is taken off the conveyor and another tank loaded at the other end. They typically run 30 pressurized tanks per day, five days per week.
Old Method
It takes 6 minutes to complete the process.
6 minutes x 348 SCFM = 2,088 SCFM (59,090 SL)
2,088 SCFx30 tanks=62,640 SCF (1,772,712 SL)
Before the EFC Installation:
Most large plants know their air cost. If the actual cost is unknown, $0.25 per 1,000 SCF (28,329 SL) is reasonable.
62,640 SCF/1,000 = 62.64 x $.25 = $15.66 air cost per day.
New Method
The EFC was installed to shut off the compressed air for the 5 minutes where no tank was present (one minute of air on).
1 minute X 348 SCFM = 348 SCF x 30 tanks = 10,440 SCF (295,452 SL)With the EFC installed:
10,440 SCF/1,000 = 10.44 x $.25 = $2.61 air cost per day
$15.66 (old cost) - $2.61 (new cost) =
$13.05 savings per day x 5 days per week =
$65.25 savings per week x 52 weeks per year =
$3,393 savings per year.
The timer was set to “on/off delay” when detecting the tanks. The best place to mount the sensor was at the oven exit that was 1 minute away from the blowoff station. Once the tank started to exit the oven, the timing sequence began and turned on the air just as the tank reached the blowoff station. The duration time of the blowoff was set at one minute.
