Solo Sprayer 2L Model 402 - Professional Mini Pressure Sprayer

Solo Sprayer 2L Model 402 - Professional Mini Pressure Sprayer

The Solo Model 402 is a compact, industrial-grade handheld pressure sprayer designed for those who require precision, durability, and commercial performance in a portable format. Unlike standard, fatiguing trigger packs, the Model 402 features a robust internal pump system that builds consistent air pressure inside the tank, allowing for a continuous, uniform spray at the simple touch of a button. Engineered with high-quality synthetic seals and a multi-directional pivoting nozzle, it is a highly versatile tool that transitions seamlessly from delicate plant misting to heavy-duty automotive cleaning or technical DIY applications. Its ergonomic handling design, coupled with an ultra-stable base profile, makes it an absolute favourite for both professional tradespeople and serious home enthusiasts alike.

Crafted with premium German engineering, this robust little sprayer completely redefines handheld fluid application. The heavy-walled, translucent tank includes high-contrast fill increments, letting you accurately gauge your water and chemical balances instantly. By using an ultra-efficient internal pump cylinder, operators can reach full working pressure with minimal strokes. The inclusion of a positive thumb locking mechanism allows you to lock the trigger in place for continuous, sweep-action spraying without finger strain. From delicate greenhouse benches to industrial workshops, this compact powerhouse delivers professional-grade spray atomisation without the bulk of a full-sized rig.

Best For: Precision tasks in the home, commercial greenhouse, or mechanical workshop where a highly consistent spray pattern, pinpoint fluid placement, and long-term tool reliability are essential.

Key Features:

• Pivoting Multi-Directional Nozzle: Features a unique adjustable nozzle assembly that rotates smoothly, allowing you to easily spray at awkward angles, paint the undersides of dense foliage, or reach deep into tight engine bays.
• High-Efficiency Pump Mechanism: Built with a heavy-duty pump piston that requires minimal down-strokes to reach full operating capacity, significantly reducing hand fatigue compared to traditional squeeze-trigger bottles.
• Adjustable Atomisation Pattern: Easily switch from a ultra-fine, penetrating mist to a coarse direct jet stream by simply twisting the ergonomic nozzle cap, providing absolute control over your product application.
• Integrated Safety Pressure Valve: Equipped with a built-in over-pressure safety valve that automatically vents excess air to maintain optimal operating limits while serving as a manual pull-pin to safely de-pressurise the unit after use.
• Ergonomic Comfort Grip: Designed with a large, contoured handle and an accessible thumb-operated trigger, featuring a continuous spray lock function for effortless coverage during extended tasks.

Primary Spraying Applications

• Conservatories & Greenhouses: Applying delicate foliar fertilizers, wetting agents, or organic contact insecticides to sensitive indoor house plants, tropical collections, and young seedlings.
• Automotive Detailing & Care: Evenly spraying alloy wheel cleaners, aggressive degreasers, multi-purpose cleaners, or window tinting prep solution where a steady, atomised mist is required for a professional finish.
• DIY & Light Construction: Moistening wallpaper backings for rapid removal, applying specialized timber preservative treatments, or spraying chemical release agents onto intricate concrete moulds.
• Sanitation & Household Hygiene: Disinfecting high-touch public surfaces, commercial kitchen counters, or hard-to-reach sanitary corners with clinical precision and speed.

Pro Tip & Seal Maintenance: To significantly extend the life of your Solo 402 sprayer, always pull the manual safety valve pin to fully release the internal compressed air when you are finished spraying. Never leave chemical solutions sitting under pressure for extended periods.

Empty the remaining mixture safely, rinse out the tank, and fill it with half a litre of clean water. Pump it up and flush the fresh water through the nozzle tip for 30 seconds. This prevents harsh chemicals, selective weedkillers, or sticky leaf glosses from drying out and crusting over the fine internal nozzle passages or degrading the premium synthetic seals!

Important Note on Availability & Shipping

Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.

Lead Times:

• In-Stock Items: Usually ready for dispatch the same day.
• Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 8–12 weeks to manufacture—they are made to order in Australia by a small business, and longer lead times reflect the care put into quality.

While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.

Biosecurity & Interstate Shipping Restrictions

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:

• Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
• Seeds cannot be shipped to Western Australia (WA).

Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
