The HMN-60 and HMN-125 are medium expansion foam nozzles suitable for use with fixed proportioning systems, or with handline proportioners for portable operation. These nozzles produce a stable, slow-draining foam with an expansion ratio of approximately 60:1, making them appropriate for vapor suppression. They are designed to produce the most effective vapor-suppression foam when used with NF foam concentrates recommended for vapor suppression.

The HMN series nozzles should be operated at an inlet pressure of 100 psi (6.9 bar). Optimum inlet pressure is 100 psi, at which the design flow rate is achieved.

The HMN-60 nozzle is equipped with 1 1/2″ swivel inlet and the HMN-125 is equipped with 2 1/2″ swivel inlet connections. An optional ball shutoff valve is available with the portable HMN series nozzles. Performance characteristics are not affected by the addition of the ball shutoff valve.
