Frequently Asked Questions
Spray Bars made in the USA!
It’s official, all of our spray bars from the Legacy all the way up to our newest TriFORCE bars are all made in the USA! Our high-quality machined parts ranging from the hub and ends to the tips are all created and sourced right here in America!
Can you rebuild the swivel components of a Whisper Wash Professional Rotary Spray System?
Yes! Unlike many other manufacturers, our swivel is completely rebuildable. The Seal Kit is usually all that is needed. Two bearings are utilized within the swivel kit. The Shaft, if bent or broken, is replaceable although this is not typical. When you ask for Whisper Wash by name you receive a system that can be maintained over time.
What is a balanced spray bar and how does it affect a flat surface cleaner?
Whisper Wash is the only manufacturer to provide a balanced and machined spray bar. The precise design and tested engineering built into every machined spray bar provides for longer bearing and seal life by eliminating unbalanced rotation. The spray tips are also always at the correct angle with the balanced rotation of the spray bar. It is superior to the pipe nipple and hydraulic spray bars provided by other manufacturers which are almost impossible to maintain a consistent balanced rotation over time.
What type of spray tips are supplied with the machines?
Whisper Wash uses standard 1/4 meg tips. The Big Guy is shipped with 25025 tips. The Classic, Ground Force, Aqua Pro, and Ultra Clean machines are equipped with 2502 tips. Other sizes may be used.
How far are the tips from the ground?
The tips rotate approximately 1-1/2″ from the ground. This provides for consistent cleaning of flat surfaces without the nuisance of zebra striping.
