The Stealth 1" Soft Wash Proportioner is engineered for high-output systems running 8+ GPM, where flow restriction is not an option. Designed for gas-powered soft wash setups, this proportioner allows you to precisely control bleach, water, and surfactant ratios while maintaining full system performance.
With dual 1" metering valves for water and bleach, plus a dedicated 1/2" surfactant valve, this system delivers unrestricted chemical flow—ensuring your pump operates at full capacity without starvation or pressure loss.
Built for Production-Level Work
- Gas-powered soft wash systems (8–11+ GPM)
- High-volume residential and commercial jobs
- Roof cleaning, large siding, and multi-story applications
- Contractors scaling production and efficiency
What size proportioner do I need for a soft wash system?
A 1" proportioner is required for systems running 8+ GPM to prevent flow restriction and maintain full output.
What happens if your proportioner is too small?
An undersized proportioner can restrict flow, reduce system performance, and cause pump strain or cavitation.
Why use a 1" proportioner on a gas soft wash system?
Gas systems produce higher flow rates, and a 1" proportioner ensures unrestricted intake and consistent chemical mixing.
True 1" High-Flow Design:
Maintains full system output with no restriction on high-GPM setups.
Dual 1" Metering Valves (Water & SH):
Precise control over your primary chemical ratios at high volume.
Dedicated 1/2" Surfactant Valve:
Controlled soap application without overuse or waste.
Batch-Free Chemical Mixing:
Adjust ratios instantly—no need to premix or stop workflow.
Prevents Pump Starvation:
Delivers consistent supply to high-demand pumps like the Comet P40.
Viton Seals for Chemical Resistance:
Built to withstand bleach and harsh cleaning solutions.
True Union Connections:
Simplifies maintenance and component replacement.
Reduced Leak Point Design:
Fewer connections increase reliability and reduce downtime.
Industrial-Grade Materials:
CPVC, polypropylene, and UHMWPE construction for long-term durability.
