Haws' new Model 7500EB.12V Portable Eyewash features a lightweight, portable design that is ideal for use in remote, cold areas. The gravity-fed eyewash employs a fold-down arm that activates flow automatically. Flushing water is heated via a 12V connection to a car or truck battery. The unit's double-insulated jacket minimizes heat loss.Haws Corp., Sparks, NV.
