Fluid control system for gas/liquid

Abstract

A fluid system has a fluid control device that can receive a gas hose and fluid hose. The fluid control device can also have a gas source and can be configured to receive the liquid hose. The fluid control device is provided to output a fluid flow into an output hose. The fluid control device can be positioned near a liquid source or a nozzle of the output hose. In another arrangement, the fluid control device can receive low pressure fluid and deliver high pressure fluid to a high pressure device. The fluid system can have a hose reel apparatus for spooling a hose connected to the fluid control device and the high pressure device.
