Plastic Air Chamber Sprayer 20L - Complete Manual Knapsack Sprayer Kit with Air Chamber Pressure Stabiliser
20-Litre Agricultural Manual Backpack Sprayer with Integrated Air Chamber, Multi-Nozzle Set & Full Accessories - Stable Pressure, Consistent Spray for Field Crop Protection
Plastic air chambe sprayer 20L
The Plastic Air Chamber Sprayer 20L is a complete manual knapsack backpack sprayer kit engineered for professional agricultural pesticide, herbicide, fungicide, and liquid fertiliser application across vegetable, rice, orchard, and field crop environments. The defining feature of this sprayer over standard rocker-arm manual sprayers is the integrated air chamber - the green dome-shaped component visible in the kit - which acts as a hydraulic accumulator between the pump outlet and the spray circuit, absorbing the pressure pulses of the manual pump stroke and releasing them as a smoothed, consistent pressure supply to the nozzle. This air chamber pressure stabilisation eliminates the pulsing, intermittent spray pattern characteristic of direct-pump-to-nozzle manual sprayers, producing a continuous, even spray mist that significantly improves chemical coverage uniformity across the crop canopy per pass. The kit is supplied complete with the 20-litre blue HDPE tank with orange frame and cap, pump assembly with air chamber, telescopic spray lance set, trigger switch handle, multi-tip nozzle set, flexible hose, shoulder harness straps, instruction manual, cap, measuring cup, and retail packaging - delivering immediate field operability without supplementary purchases.


Technical Profiles & Materials
1. Integrated Air Chamber - Continuous, Pulse-Free Spray Delivery The green polypropylene air chamber dome is the key performance differentiator of this sprayer. Connected in-line between the pump outlet and the spray hose circuit, it traps a volume of compressed air above the liquid column inside the dome. During each pump stroke, this air volume compresses further and then expands between strokes - maintaining hydraulic pressure in the spray circuit continuously rather than delivering pressure only during the active pump stroke.
2. Blue HDPE Tank with Orange Structural Frame - Chemical-Resistant, Ergonomic Carry The 20-litre tank is manufactured from high-density polyethylene with resistance to the full spectrum of agricultural pesticide, herbicide, and fertiliser solutions used in crop protection programmes. The orange structural frame distributes loaded tank weight across both shoulder straps via the harness attachment points, reducing concentrated shoulder pressure and improving operator carrying comfort during sustained field spraying sessions.
3. Complete Multi-Tip Nozzle Kit & Telescopic Lance Set The included multi-tip nozzle set - comprising flat fan, hollow cone, and direct jet tip options - enables operators to select the correct spray pattern for each chemical application programme without additional nozzle purchases. The telescopic lance adjusts to multiple lengths to match crop canopy height and operator stature, improving spray accuracy and reducing the fatigue caused by awkward fixed-length wand positioning across different crop types. The flexible hose connection between the tank pump outlet and the lance provides freedom of wand movement without pulling on the tank straps.

Products Application

Vegetable Farm Pesticide & Foliar Fertiliser Application
Commercial vegetable growers applying insecticides, fungicides, and foliar fertilisers across dense crop canopies require consistent, even spray coverage on every leaf surface to achieve effective chemical uptake and pest control. The air chamber pressure stabiliser eliminates the uneven, pulsing spray pattern of standard pump-direct sprayers - ensuring the nozzle delivers a continuous, uniform mist across the canopy row in each pass. This coverage consistency reduces the risk of under-treated zones that allow pest and disease escapes, and over-treated zones that cause phytotoxic chemical burn on sensitive vegetable crops.

Rice Paddy Herbicide & Insecticide Spraying
Rice farmers applying pre- and post-emergence herbicides and insecticides across flooded paddy fields require a sprayer that delivers stable, consistent pressure to the nozzle throughout each spray pass - including during the pause between pump strokes when the operator steps between paddy row paths. The air chamber maintains spray pressure during these inter-stroke pauses, preventing the spray cut-off and restart gaps that cause uneven herbicide distribution and leave untreated zones within paddy rows - significantly improving herbicide efficacy and reducing the need for follow-up application passes.

Municipal Green Space & Vegetation Management
Municipal maintenance teams, landscaping contractors, and property management companies responsible for parks, roadside verges, golf courses, and ornamental garden areas rely on the 20-litre air chamber sprayer for herbicide and pesticide application along pathways, shrub borders, and turf areas. The air chamber's continuous, pulse-free spray delivery is particularly valuable in ornamental and municipal settings where consistent droplet coverage - without the pulsing gaps of standard manual sprayers - directly affects the evenness of herbicide activity across treated surfaces.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
