Why
Low Pressure Nozzles?
There
has been a trend in the fire service for several years to
utilize greater water flow for initial attack. The most popular
delivery system seems to be 1.75" hose with a lightweight
nozzle (or nozzle combination) that will deliver from 150 to 225
GPM. Even with lightweight synthetic hose, this flow range can
be hard to handle because of the reaction force the nozzle team
encounters.
There are two ways to reduce reaction force: flow less water;
or reduce the nozzle pressure at which the water is being
discharged. By reducing the flow you will also reduce your fire
fighting capabilities (water still puts out the fire); but by
reducing the nozzle pressure to apply that flow, you merely
reduce the reaction force of the fire stream...and that equates
to less wear-'n-tear on the nozzleman!
The nozzles shown on this page deliver their rated flows at
50 or 75 psi rather than the normal 100 psi; consequently, the
reaction force of like flows will be less with these low
pressure nozzles.

Mystery
Low Pressure Nozzles
Constructed
of durable, lightweight Elk-O-Lite with a heavy-duty protective
EPDM bumper; these nozzles are ideal for Hi-Rise or ground level
operations. Like all mystery nozzles, these feature excellent
stream quality from full wide fog to a tight, straight stream,
with the capability of turning the nozzle tip to complete
shutoff. Any of these nozzles can be used with Elkhart's
lightweight Elk-O-Lite ball shutoffs to make a variety of
break-apart combinations. Many low pressure flows are available. |
