TF-825B4
Farmate
As a trusted product under Farmate’s commercial line, it combines robust performance with user-friendly features, addressing the needs of tasks that require larger coverage than small-scale sprayers but without the bulk of industrial equipment. Supplied as 1 unit, the TF-825B4 is ready for immediate deployment, with a focus on durability, efficiency, and consistent spray quality—key factors for commercial users who rely on equipment to maintain productivity. Its design prioritizes long-term use: components are selected to withstand frequent operation in high-demand environments, from humid greenhouses to dusty orchards, making it a reliable investment for commercial plant care.
At the core of the TF-825B4 is a 12V 800mAh rechargeable electric motor, which delivers consistent power for up to 4 hours of continuous spraying on a single charge. Unlike manual pump sprayers that rely on physical effort (leading to inconsistent pressure and operator fatigue), this electric motor ensures steady pressure throughout the task—resulting in uniform coverage across large areas like a 1,000-square-meter greenhouse. The motor operates at a low noise level (below 65dB), making it suitable for use in residential areas or indoor greenhouses where noise disruption is a concern. For commercial users who work long shifts, the electric design eliminates the need for manual pumping, reducing physical strain and increasing overall efficiency.
The sprayer features a 5L high-density polyethylene (HDPE) tank, which is not only lightweight but also 100% leak-proof—thanks to a reinforced lid with a silicone gasket. The large capacity is a critical advantage for commercial users: it reduces the frequency of refills, allowing operators to cover more ground without interruptions. For example, a greenhouse manager can spray an entire row of tomato plants (approx. 50 meters) without stopping to refill. The tank also includes a clear level indicator, allowing users to monitor fluid levels at a glance and plan refills efficiently. The HDPE material is resistant to chemicals and impacts, ensuring the tank remains intact even if accidentally dropped or exposed to harsh pesticides.
To enhance versatility and safety, the TF-825B4 is equipped with an intelligent pressure control system that allows users to adjust pressure between 0.2MPa and 0.8MPa. This range caters to diverse tasks: lower pressure (0.2-0.4MPa) for misting delicate greenhouse seedlings, and higher pressure (0.6-0.8MPa) for penetrating dense orchard foliage. Additionally, a safety lock on the spray trigger prevents accidental activation—reducing the risk of chemical exposure or waste, especially when transporting the sprayer between greenhouses or orchard rows. For teams sharing equipment, this safety feature ensures that the sprayer won’t be triggered accidentally by untrained users, minimizing risks in busy commercial settings.
Greenhouse managers tending to rows of tomatoes, cucumbers, or ornamental plants will benefit significantly from the TF-825B4’s efficiency. The electric motor’s steady pressure ensures uniform distribution of fungicides, insecticides, or growth regulators across hundreds of plants—critical for preventing the spread of diseases in enclosed greenhouse environments. The 5L tank minimizes refill stops, while the low-noise operation won’t disturb beneficial insects (like bees) often used in greenhouse pollination. For operators who manage multiple greenhouses, the sprayer’s portability (weighing 4.8kg when full) allows easy transport between facilities, making it a versatile tool for daily operations.
For orchard operators with apple, citrus, or peach trees, the TF-825B4’s adjustable pressure and powerful spray reach (up to 3 meters) make it ideal for targeting pests hidden in tree canopies. The high-pressure setting allows the mist to penetrate thick foliage, ensuring that pesticides reach leaves and fruits at all heights—from the lower branches to the top of 3-meter-tall trees. The leak-proof tank prevents chemical spills that could harm soil or root systems, which is crucial for orchard sustainability. For commercial orchard owners who spray large areas (5+ acres), the TF-825B4’s long battery life and large tank reduce downtime, allowing teams to complete tasks faster.
Landscaping companies working on urban projects—such as park greenery, roadside flower beds, or corporate campus landscapes—will find the TF-825B4 highly practical. Its portability allows easy transport between job sites (it fits in most utility van storage compartments), and the durable HDPE tank withstands the wear and tear of daily commercial use. The adjustable spray pattern caters to diverse plants: from low-lying ground cover (using mist) to tall shrubs (using high pressure). For projects in busy urban areas, the low-noise motor ensures that work doesn’t disrupt nearby businesses or residents, making the TF-825B4 a professional, neighbor-friendly choice.
The sprayer’s 12V 800mAh battery takes approximately 2.5 hours to fully charge using the included AC adapter. A full charge supports up to 4 hours of continuous spraying, though this may vary slightly based on pressure setting (higher pressure uses more power). For commercial users who start work early, charging the sprayer overnight ensures it’s fully powered for a full day of tasks.
Yes, the HDPE tank is highly resistant to both acidic (e.g., sulfuric acid-based fertilizers, iron chelates) and alkaline (e.g., lime sulfur solutions, potassium hydroxide-based cleaners) chemicals. This compatibility makes the TF-825B4 suitable for a wide range of commercial plant care products, eliminating the need to purchase separate sprayers for different solutions.
Absolutely. The TF-825B4’s adjustable pressure and uniform atomization make it perfect for foliar feeding—delivering liquid nutrients directly to plant leaves for faster absorption. We recommend using the medium pressure setting (0.4-0.6MPa) for foliar applications: this ensures even coverage without damaging leaf tissue, which is critical for maximizing nutrient uptake in commercial crops like lettuce or strawberries.
Routine maintenance is simple and time-efficient—critical for busy commercial users. After each use, rinse the tank and nozzle with clean water to remove residue. Every 3 months, check the battery connection for corrosion (clean with a dry cloth if needed) and lubricate the trigger mechanism with a small amount of silicone oil. The motor is sealed and requires no additional maintenance, ensuring the sprayer remains operational with minimal upkeep.
