What our Experts Think    
  • Built as a high-output professional softwash skid system, combining 300 PSI low-pressure cleaning with 11.5 GPM high-flow delivery for rapid surface coverage and chemical application
  • The AR45 diaphragm pump is a proven choice for softwashing setups, valued for its chemical resistance and consistent flow under continuous duty
  • Powered by a 6.5 HP Vanguard engine with electric start, offering reliable ignition and stable performance for daily commercial use
  • Designed for roof washing, siding restoration, and large exterior surface cleaning, where chemical dwell time matters more than high pressure
  • Experts highlight the system’s strength in fast coverage efficiency, reducing job time on large residential and light commercial projects
  • Skid-mounted configuration supports truck or trailer installation, making it ideal for mobile cleaning businesses
  • The 11.5 GPM flow is a key advantage for professionals looking to maximize rinse speed and chemical distribution per pass
  • Considered best suited for established pressure washing contractors, not entry-level users due to chemical handling and system complexit

Q: What surfaces can this softwash system clean?
A: It is ideal for roofs, vinyl siding, stucco, wood, fences, decks, and other exterior surfaces that require gentle but effective cleaning.

Q: What is the benefit of the high GPM (11.5)?
A: The high flow rate ensures fast application of cleaning solutions, improving coverage and reducing total job time on large exterior surfaces.

Q: What role does the AR45 pump play?

Maintenance Tips    
  • Flush the AR45 diaphragm pump, hoses, and tank system with clean water after every use to prevent chemical (bleach/surfactant) crystallization and internal damage
  • Never leave softwash chemicals sitting in the system—drain and rinse immediately after operation to protect valves and diaphragms
  • Inspect and clean inlet filter/strainer regularly to prevent debris from restricting flow or damaging the pump head
  • Check oil level and condition in the 6.5 HP Vanguard engine and follow scheduled oil changes for consistent starting and power delivery
  • Keep air filter clean to maintain proper combustion, especially in dusty job-site environments
  • Inspect AR45 pump fittings, pulse dampener, and hose connections for leaks or chemical seepage before each use
  • Avoid dry-running the pump—always ensure liquid supply is primed before engaging the system
  • Use only compatible softwash nozzles and tips to maintain correct low-pressure, high-volume output (300 PSI / 11.5 GPM system design)
  • Store the skid unit in a dry, shaded area to prevent corrosion on frame, pump manifold, and engine components
  • Winterize system in freezing conditions by fully draining all water lines, pump, and hoses to prevent cracking
  • Periodically check battery (electric start system) terminals and charge level for reliable ignition performance
