Viking's Freedom® VK479 Residential Horizontal Sidewall Sprinkler is cULus Listed with a flow rate of 11 GPM (42 L/min) and a pressure requirement of 13.4 PSI (0.92 bar) in a 12 x 12 ft (3,7 x 3,7 m) room size. With its smaller K-factor and lower Listed flow rates, the VK479 is well-suited for 13D residential systems where the available water supply is a concern. In addition to the 12 x 12 ft room size, the sprinkler is also cULus Listed for 14 x 14 ft (4,3 x 4,3 m) and 16 x 16 ft (4,9 x 4,9 m) coverage areas.
The VK479 has a 1/2 in (15 mm) NPT thread size and a temperature rating of 155°F (68°C). In addition to standard finishes, a durable ENT plating (Nickel PTFE) that resists corrosion, chipping and flaking is also offered.
