Compressed Air Blow Off System Materials of Construction
All Ring-Blade™ Air Wipes are coated aluminum construction with stainless steel shims and brass fittings. Standard units come with rubber hose connecting the twin peices. High temperature units come with stainless steel hose.
See Price List for description of each part number.
Compressed Air Blow Off System Is Cost Effective
Example Of An Air Saving Calculation
1. From the chart showing air flow through a hole, assume we have a circular tube that is 4" in diameter. It has a circumference of 3.14159 X diameter or 12.57 inches. Assume it has 1/16" holes spaced ½ apart with a total number of 24 holes. The air pressure in the system is 60 PSIG.
2. From the chart each 1/16" hole consumes 4.23 SCFM at 60 PSIG. Total air consumed is 24 X 4.23 = 101.52 SCFM.
3. From the compressed air consumption chart , a 4" diameter Ring-Blade consumes 49 SCFM at 60 PSIG.
4. Assuming a compressed air cost of 30 cents/1000 standard cubic feet and an 8 hour day operation for 200 days per year.
The Drilled Circular Tube Will Cost:
