WebNov 11, 2011 · Low pressure air compressors are used when a dry pipe sprinkler system uses a high water to air ratio valve (typically 1 lbs. of air to every 8 lbs. of water). Currently Victaulic, Reliable and Tyco manufacture these high ratio valves. Low pressure air compressors can also be used on pre-action systems where the air is only used for … WebAny precipitation is usually shunted around the periphery of the high-pressure area. High pressure aloft causes the air to subside or sink. This downward motion compresses and warms the air in the lower atmosphere while simultaneously trapping heat rising from the earth's surface, leading to heat waves. The skies are usually clear due to the ...
