| Compressed Air Consumption |
| for |
| Templex Waste Removal Systems |
GENERAL INFORMATION
|
CFM = Cubic feet per minute |
| LPS = Liters per second |
| LPM = Liters per minute (LPS x 60 = LPM) |
| 1 CFM = 28.3 LPM (.47195 LPS x 60 = 28.3 LPM) |
| PSI = Air Pressure- Pounds per square inch |
| 1 PSI = .06895 Bar Example: 80 PSI = (.06895 x 80) = 5.5 Bar |
Typical Air Compressor Capacity
Piston Type: Each 1 HP Generates approximately 3 SCFM or 84.9 LPM
Screw Type: Each 1 HP Generates approximately 4 SCFM or 113.2 LPM
Example: A 25 H.P. Screw Type air compressor will produce 100 SCFM or 2830 LPM (liters per minute) (25hp x 4 scfm) = 100 scfm or (25 hp x 28.3 lpm) = 2830 LPM.
The air consumption for chain removal only will be the same for a Templex Dual Chain & Waste Removal System. Always use a TBV-400 Dual Chain & Waste Removal Vacuum Assembly when vacuum is needed for both a chain cutter and trimmed waste removal to conserve compressed air.The Templex chain removal vacuum and the dual chain and waste removal vacuums operate best at 80 psi or 5.5 bar.Compressed air consumption will vary from machine to machine depending on air pressure, flow control adjustment, weight of fabric, thread, and actual sewing cycle.
EXAMPLE 1: 40 overlock/safety stitch machines sewing a light weight to medium weight knit or woven fabric using T- 150 texturized poly or 100s/2 cord spun polyester thread.
| AIR PRESSURE: 80 psi or 5.5 bar. |
| SEWING CYCLE: 50% to 60% |
| FLOW CONTROL ADJUSTMENT: opened counter clockwise one mark on Treadle Rod Air Switch. |
CFM used Per Machine (approximate) = 2 to 2.5 cfm. CFM total: 2.5 cfm x 40 machines = 100 scfm
Compressor Recommendation: Minimun of 25 HP Screw Type (100 Total cfm � 4 = 25 HP) or minimun of 35 HP Piston Type (100 Total cfm � 3 = 35 HP). Consider next compressor size up to allow for future needs.
EXAMPLE 2: 30 overlock / safety stitch machines sewing a heavy denim fabric using a 40s/3 cord cotton thread.
| AIR PRESSURE: 80 psi or 5.5 bar |
| SEWING CYCLE: 70% |
| FLOW CONTROL ADJUSTMENT: opened counter clockwise two marks on Treadle Rod Air Switch. |
CFM used Per Machine (approximate) = 3.5 to 4 cfm. CFM total: 4 cfm x 30 machines = 120 scfm
Compressor Recommendation: Minimun of 30 HP Screw Type (120 Total cfm � 4 = 30 HP) or minimun of 40 HP Piston Type (120 Total cfm � 3 = 40 HP). Consider next compressor size up to allow for future needs.
IMPORTANT!! These are estimates and may vary depending on proper installation and size of main air supply trunk line, altitude, proper installation of Templex waste removal products, and percentage of pressure drop when vacuum is activated
