BRYKFIRE Mobile unit is mainly used by fire & rescue services as a handy complement to fixed concentrate proportioning systems. Just connect to the fire hoses and insert the suction tube into a concentrate tank, and it is ready to be used! Equipped as standard with an Automatic air relief valve to speed up the suction from the pump. On units provided with a gear pump (- GP) the suction from the unit is automatic. The extinguishing media concentrate needs to be in line with the dosing pump on our mobile models with a piston pump (- PP).
