Protek's Multi-Purpose Nozzles are technologically advanced nozzles with both solid bore and fog stream capability. The nozzle offers the flexibility to flow both at the same time or independently. Solid bore provides excellent reach and penetration at low pressure, while fog stream offers protection and rapid cooling. Inlet size is available in either 1-1/2" (38 mm) or 2-1/2" (65 mm). Nozzles are capable of operating efficiently at pressures as low as 50 psi to reduce fire fighter fatigue or up to 100 psi for maximum flow. All Protek nozzles are NFPA compliant.
