The early suppression fast response (ESFR), Model AG-14 designed to response quickly to growing fires with a high volume of water discharge to “suppress” rather than “control” fires. The deflector and frame provide a broad, very symmetrical, hemispherical pattern capable of suppressing fires between sprinklers in high storage height areas and at the same time retaining a high momentum central core to penetrate and suppress fires occurring directly beneath the sprinkler in low storage height areas.
The ESFR sprinkler model AG-14 is intended for protection of palletized and solid piled and open frame single row, double row, multiple row and portable rack storage of most common materials including unexpanded and cartoned expanded plastics. This sprinkler was designed to be shorter, and more compact than other ESFR sprinklers. The shorter sprinkler allows piping to be installed further from the ceiling and obstructions. It sprinkler is also less susceptible to damage due to smaller deflector and frame design.
