In this review of the Pressure Washer VRT 3 Unloader the bottom line is simple: it is a practical replacement unloader for operators who need reliable pressure and flow control without extra complexity. Designed to handle up to 3,630 PSI and 10.5 GPM, the VRT 3 is best for service techs, rental stores and experienced DIYers who replace worn unloaders on pumps from Comet, AR North America or General Pump. The unit's straightforward plumbing with 3/8' FNPT inlets, outlets and by-pass, and its blue adjustment knob make pressure tuning quick on the worksite.

Key Features

• High pressure capacity: Handles up to 3,630 PSI so it is suitable for heavy-duty cleaning tasks and high-pressure pump setups.
• High flow handling: Rated to 10.5 GPM which keeps performance steady on larger surface cleaning rigs and multi-gun systems.
• Standard 3/8' FNPT ports: Inlet, outlet and by-pass use 3/8' FNPT threads to simplify plumbing and minimize the need for adapters.
• Temperature tolerance: Max operating temperature of 194 F lets it work with hot water systems within common commercial ranges.
• Blue pressure knob: The included blue knob provides quick, visible pressure adjustments for tuning performance on the fly.
• Responsive control: Designed to react to pressure increases or flow changes so the pump is protected when the trigger gun is closed.
