N.A.ROBSON NOZZLES
- 1. Tungsten Carbide Aluminium Jacket Nozzle Nozzle Size NTL-450 1/4” Tungsten NO.5 NOZZLE BORE Tungsten carbide nozzles have long carbide Venturi No4 1/4" / 8.0mm been the traditional material selection LENGTH- 5 1/4" /136mm AIR REQUIREMENT for most general nozzle applications 150/170 CFM and where medium cutting abrasives NTL-550 5/16” Tung- NO.5 NOZZLE BORE like glass bead, steel shot & grits, or sten carbide Venturi 5/16" / 8.0mm No5 LENGTH- 5 3/4" /147mm Copper slag are used. AIR REQUIREMENT 150/170 CFM These widely used, robust nozzles are NTL-650 3/8” Tungsten NO.6 NOZZLE BORE the preferred choice of blast cleaning carbide Venturi No6 3/8" / 9.5mm LENGTH- 7" /180mm operators, as it has excellent durability AIR REQUIREMENT & wear when using the hard abrasive. 250/265 CFM NTL-850 1/2” NO.8 NOZZLE BORE Tungsten Carbide ½” / 12.5mm Venturi No8 LENGTH- 9 1/4" /235mm AIR REQUIREMENT 350/425 CFM Silicon Composite Nozzle Silicon nozzles are probably the most Nozzle Size popular alternative to tungsten carbide SCC-450 ¼” Silicon NO.4 NOZZLE BORE for blast nozzle applications. The low Composite Venturi 1/4" / 8.0mm Nozzle No4 LENGTH- 5 1/4" /136mm wear rate maintains the internal nozzle AIR REQUIREMENT geometry and provides maximum 150/170 CFM blasting effectiveness, minimum SCC-550 5/16” Silicon NO.5 NOZZLE BORE Composite Venturi 5/16" / 8.0mm compressor requirements and reduced Nozzle No5 LENGTH- 5 3/4" /147mm downtime due to replacement. AIR REQUIREMENT 150/170 CFM SCC-650 3/8” Silicon NO.6 NOZZLE BORE Silicon is also about one fifth lighter Composite Venturi 3/8" / 9.5mm than Tungsten Carbide, so it is an Nozzle No6 LENGTH- 7" /180mm AIR REQUIREMENT excellent choice to minimize operator 250/265 CFM fatigue and maximize productivity. SCC-750 7/16” Silicon NO.7 NOZZLE BORE Composite Venturi 7/16” / 11.0mm Nozzle No7 LENGTH- 8” /200mm AIR REQUIREMENT 350/375 CFM Boron Carbide Nozzle The Boron carbide blast nozzle offer a Nozzle Size longest life with optimum air and Boron Carbide Nozzle NO.5 NOZZLE BORE abrasive use. Boron Carbide blasting 550 5/16" / 8.0mm nozzles offer the greatest resistance LENGTH- 5 3/4" /147mm AIR REQUIREMENT to nozzle wear. 150/170 CFM Boron Carbide Nozzle NO.6 NOZZLE BORE Its weight is similar to Silicon Carbide 650 3/8" / 9.5mm LENGTH- 7" /180mm and is much lighter than Tungsten AIR REQUIREMENT Carbide. Boron Carbide is a far 250/265 CFM superior .
- 2. Boron Alloy Nozzle Boron Alloy cast flanged blast nozzles is used for those short lasting contract Nozzle Size jobs or for the part time Blaster BANF—550 Thread 1" and 1 1/4" Nozzle holder. Boron Alloy Nozzle It has to be held in place by a BANF—650 Thread 1" and 1 1/4" Nozzle holder. lightweight Retaining Nut to Secure the Boron Alloy Nozzle Nozzle in place BANF—750 Thread 1" and 1 1/4" Nozzle holder. Boron Alloy Nozzle Suits all standard coarse Thread 1" and 1 1/4" Nozzle holder.
