Description

The Suttner ST-60F 1.6 Downstream Chemical Injector is a precision-engineered fluid mixing component designed specifically to work in tandem with the Suttner ST-75 Foam Nozzle. This specialized injector is optimized to draw foaming agents and detergents into the water stream at a controlled rate, ensuring the ST-75 foamer receives the perfect air-to-chemical ratio to produce a thick, rich lather.

The 1.6 mm nozzle sizing makes this injector ideal for mid-range flow pressure washers looking to achieve reliable chemical suction and consistent foam production.

Key Features

• Perfect ST-75 Synergy: Specifically calibrated to provide the exact backpressure and fluid dynamics required by the ST-75 foaming nozzle to generate high-cling, heavy snow foam blankets.

• Corrosion-Resistant Internals: Built with high-grade materials to withstand continuous exposure to aggressive detergents, bleach (SH), and surfactants without losing performance.

• Efficient Downstream Injection: Allows for the application of soaps and chemicals after the pressure washer pump, completely protecting the pump’s internal seals and valves from chemical damage.

• Precise 1.6 mm Metering: The fixed 1.6 mm restriction nozzle optimizes the venturi effect, ensuring a reliable draw of chemical concentrate even through longer lengths of high-pressure hose.

Technical Specifications

• Brand: Suttner

• Model: ST-60F

• Nozzle/Orifice Size: 1.6 mm

• Compatibility: Optimized for the Suttner ST-75 Foamer Nozzle

• Maximum Pressure: Rated for heavy-duty commercial pressure washer systems (typically up to 4,000–5,000 PSI depending on the specific housing setup)

• Inlet/Outlet Connections: Designed for standard high-pressure plumbing integration (typically 3/8″ or 1/4″ configurations depending on the exact sub-model fittings)

Common Applications

• Commercial Vehicle & Fleet Washing: Delivers the steady chemical flow needed to rapidly blanket trucks, buses, and trailers in thick pre-wash foam.

• Agricultural & Barn Sanitation: Works perfectly in livestock facilities to inject heavy-duty disinfectants and sanitizing foams onto walls and flooring.

• Food Processing & Kitchen Cleanup: Enables touchless foaming of industrial meat-packing or food prep equipment using specialized hygiene chemicals.

• Property Maintenance: Ideal for applying soft-wash chemical mixes to roofs, siding, and walkways when paired with the proper terminal foam lance.
