The Silicon Nitride "Syalon" Syclone Venturi Nozzle with Acetal Jacket is an abrasive blast nozzle range (part numbers MT28446-4C through MT28446-8N) used to direct and accelerate grit during abrasive blast cleaning. Operator fatigue and nozzle wear both add cost to a blasting job, and the Silicon Nitride "Syalon" Syclone Venturi Nozzle with Acetal Jacket addresses the first by cutting weight and the second through a hard, durable liner material.

The silicon nitride liner reduces the weight of the Silicon Nitride "Syalon" Syclone Venturi Nozzle with Acetal Jacket by approximately 50%, which eases handling over a working shift. The liner also offers high temperature resistant properties and resistance to corrosion by many acids and alkalis, widening where the nozzle can be used. The acetal jacket adds improved impact protection against the knocks and drops common on site, and each Silicon Nitride "Syalon" Syclone Venturi Nozzle with Acetal Jacket is supplied with a rubber gasket for sealing to the hose coupling.

The venturi bore is offered in nozzle numbers 4 to 8, with orifice diameters from 6.35mm up to 12.5mm, lengths from 135mm to 235mm, and a common 32mm entry diameter, so the Silicon Nitride "Syalon" Syclone Venturi Nozzle with Acetal Jacket can be matched to compressor output and the surface being cleaned. The range of the Silicon Nitride "Syalon" Syclone Venturi Nozzle with Acetal Jacket conforms to the European Union PED and the American Society of Mechanical Engineers ASME requirements across the contractor and NPSM thread versions.
