  • It has three discharging points: the center stream towards the center of the tank and left and right points close to the tank wall.
  • It is fitted with a Teflon style vapor seal that prevents tank vapors from escaping the tank through the nozzle’s air aspiration holes.
  • It is manufactured from 316 stainless steel with stainless steel screens on the air inlets.
  • Each unit has a 4” flat face ANSI 150 lb inlet flange and available with either a 4”, 6”, 8” or 10” mounting flange to fit into existing tank shell holes.

The Hollow Point nozzles are fitted with a Teflon style vapor seal that prevents tank vapors from escaping the tank through the nozzle’s air aspiration holes. This vapor seal is ruptured upon activation of the nozzles and can be replaced easily by separating two flanges and sliding in a new unit. Hollow Point is manufactured from 316 stainless steel with stainless steel screens on the air inlets. Each unit has a 4” flat face ANSI 150 lb inlet flange and available with either a 4”, 6”, 8” or 10” mounting flange to fit into existing tank shell holes. For new installations (or for instances where new holes will be cut), it is recommended to use the unit with 4” mounting flange.
 Multiple Hollow Point devices will be required for each tank size. When ordering, please supply the following information:

·Inlet pressure available at the base of the Hollow Point system (100 psi or 6.9 bar inlet   pressure is recommended for optimum foam quality, but lower pressure may be acceptable).
·Tank diameter.
·Product in the tank.
·Foam to be used.
·Existing foam system (if any).
