Back blow nozzle Model 1008SS

aircleaningcooling

Overview
Back Blow Air Nozzles are engineered to clean the inside of pipes, tubes, hoses or channels by producing a 360° annular air pattern directed back toward the inlet. They remove coolant, chips and debris generated by machining without pushing chips further into the part. Suitable for a range of inside diameters from 1/4" (6.3 mm) up to 16" (406 mm). Personal protective equipment is recommended because airflow is directed toward the operator.

Applications

• Part cleaning
• Chip removal
• Liquid blowoff
• Part cooling
• Material conveying
• Part ejection
• Fiber conveying
• Air assist

Advantages

• Reduced compressed air consumption compared with open tubes
• Approx. 10 dBA average noise reduction (model-dependent)
• Improved blowoff performance with lower air use
• Compact, easily mounted design
• Improved operator safety versus direct blow
• Meets OSHA dead-end pressure and applicable noise requirements
• Supports higher production throughput

Materials
Type 316 Stainless Steel — suitable for elevated temperatures, corrosive environments and mechanical wear. Maximum temperature: 1000°F (538°C).

Accessories
Chip Shields

• Model 901650 — for M4 x 0.5 extensions (protects operators from flying debris)
• Model 901222 — for 1/4 NPT extensions

Aluminum Extension Pipe
Extensions provide reach to clean inside pipes, tubes, hoses or channels; available up to 72" (1829 mm). Example models include:

• 9492 — 6" (152 mm) Aluminum, M4 x 0.5
• 9493 — 12" (305 mm) Aluminum, M4 x 0.5
• 9495 — 24" (610 mm) Aluminum, M4 x 0.5
• 9497 — 36" (914 mm) Aluminum, M4 x 0.5
• 9188 — 12" (305 mm) Aluminum, 1/4 NPT
• 9194 — 72" (1829 mm) Aluminum, 1/4 NPT
• 900353 — 12" (305 mm) Aluminum, 1" NPT

Performance (example models)

• 1004SS — 4.5 SCFM (127 SLPM), 75 dBA — use with inside diameters 1/4"–1" (6.3–25.4 mm)
• 1006SS — 22 SCFM (622 SLPM), 80 dBA — use with inside diameters 7/8"–4" (22–102 mm)
• 1008SS — 57 SCFM (1,614 SLPM), 89 dBA — use with inside diameters 2"–16" (51–406 mm)

How It Works (summary)
Nozzles use the Coanda effect to amplify compressed airflow up to 25× or more. Air is ejected from an annular ring of outlets angled to form a cone of high-velocity air directed back toward the inlet. The result is a high-volume, high-velocity airstream with minimal consumption while maintaining OSHA dead-end pressure compliance.
