Jenny's line of fire sprinkler stationary compressors is designed to load sprinkler lines with compressed air rather than water. Twelve models are offered, each in base-plate-mounted and tank-mounted configurations. The smallest unit will accommodate a system requiring 220 gals. of air compressed within 30 minutes, while the largest unit will compress 2,115 gals. within that half-hour window. Horsepower output ranges from 1/3 to 5, and the systems deliver between 2.9 and 26 cfm at 40 psi. Each unit comes with a heavy-duty cast iron compressor pump and is belt-driven with an extra large flywheel for extra cooling and easier start up.
