Solo Sprayer 7L Model 409 - Professional Garden Pressure Sprayer

Solo Sprayer 7L Model 409 - Professional Garden Pressure Sprayer

The Solo Model 409 is a high-capacity, heavy-duty pressure sprayer specifically engineered to withstand the rigours of demanding garden maintenance and harsh outdoor conditions. Featuring a generous 7-litre tank, it bridges the gap between small handheld units and large backpack sprayers, offering enough volume to cover significant yard areas without the weight of a full shoulder rig. Built with high-grade UV-stabilised plastics and premium fittings, the Model 409 is designed for longevity and reliability, making it the go-to tool for serious home gardeners, landscapers, and property owners who demand professional results from their maintenance equipment.

Crafted for optimal fluid delivery and ease of use, this robust sprayer features a large-diameter funnel opening that makes pouring, mixing, and rinsing completely spill-free. The chemical-resistant tank walls are translucent, allowing you to monitor your remaining fluid levels at a single glance. By combining structural strength with an efficient, high-volume pump module, the sprayer allows operators to establish target working pressures with fewer strokes, maintaining a highly uniform spray pattern for longer periods between pumps. Whether applying liquid nutrients or treating extensive perimeters, this versatile unit delivers industrial performance right to your hip.

Best For: Homeowners with medium-to-large yards, hobby farmers, and property maintenance crews who need a durable, high-volume sprayer for lawn treatments, fence-line spraying, and general garden pest control.

Key Features:

• Generous 7-Litre Capacity: Provides extended spraying run times, allowing you to treat larger spaces like long driveways or expansive fence lines with fewer refills.
• Premium UV-Stabilised Build: Constructed from premium-grade, UV-stabilised polyethylene that resists chemical degradation and won't become brittle or crack under intense sunlight.
• High-Efficiency Internal Pump: Features a powerful, easy-action piston pump that allows you to reach optimal operating pressure quickly and maintain a consistent spray trajectory.
• Professional Lance & Nozzle Assembly: Equipped with a durable spray wand and an adjustable nozzle tip that shifts smoothly from a direct stream for height to a fine fan mist for even surface coverage.
• Ergonomic Pump & Carry Handle: The heavy-duty pump handle double-functions as a sturdy carrying grip, paired with an adjustable woven shoulder strap for effortless transport across the yard.

Primary Spraying Applications

• Large-Scale Weed Control: Ideal for applying non-selective knock-down herbicides over gravel driveways, large paved parking segments, or boundary firebreaks.
• Lawn Health Maintenance: Perfect for blanket spraying selective broadleaf weedkillers across established lawns to cleanly eliminate widespread infestations of clover, flatweed, and bindii.
• Orchard & Canopy Protection: Easily reaches deep into the canopy of citrus, olive, or stone fruit trees with the rigid wand to apply organic pest controls, foliar fertilizers, or protective treatments.
• External Structural Barriers: Applying a uniform perimeter barrier spray of residual insecticide around the entire concrete foundation of a standard family home in a single tank.

Pro Tip & Pump Maintenance: When mixing your 7-litre solution, always fill the tank halfway with fresh water first, add your measured chemical concentrate, and then top it up with water to the 7L mark. This creates an immediate vortex that ensures a perfect, uniform mix and prevents heavy concentrates from settling unmixed at the base of the tank.

After finishing your application, vent the air pressure using the safety relief valve, empty any leftover chemical responsibly, and pump 1 to 2 litres of clean water through the lance. This simple flush prevents chemical residues from drying out and clogging the internal nozzle seat, keeping your Solo sprayer flawless for years!
