Protek's 333 self-protection multifunctional water gun adopts advanced technology and can support the simultaneous activation of DC and spray modes. The DC or spray mode can also be turned on flexibly. Under low working pressure conditions, the DC mode can still achieve effective range and excellent penetration. At the same time, the spray mode can provide a rapid cooling water curtain, giving the firefighters maximum protection on the fire scene. The water inlet size is 2.5" (65mm) quick plug. The water gun can work efficiently at pressures as low as 3.5 bar to reduce fatigue of firefighters, or provide a maximum flow of 510 LPM at pressures as high as 7 bar.
