Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd designs and manufactures pipeline connection and cordless construction equipment in Hangzhou, China. Our Engineering Construction Pipeline Connection Solutions range covers pipe cutting, threading, tightening and pressure testing, together with the cordless tools that support those operations on site. As a Lithium-Ion Spray Gun manufacturer, we build 21V brushless spray guns that atomize paint and protective coatings without an air compressor.
Coating is the finishing step that follows cutting, threading and assembly. Touching up pipe supports, hangers, brackets and equipment frames on site keeps the work with one crew and avoids sending pre-treated parts back to a workshop. Our spray guns are configured for that role: cordless, mobile, and adjustable across the coatings used in fire protection, building services and industrial maintenance.
Our Lithium-Ion Spray Gun Range
Two 21V models cover the span from small-area touch-up to industrial-grade coating. Both run on brushless lithium-ion power, and both remove the compressor, air hose and power cord from the work area.
21V Lithium-Ion Cordless Spray Gun — Small Airplane Model
A portable cordless painting tool built around high-pressure atomization. The 21V brushless system atomizes paint evenly for a wide coverage area and a smooth, flat film without runs or orange peel, and it does so without an air compressor.
- Adjustable flow rate and spray pattern for different coatings and part sizes
- Lightweight body and comfortable grip for overhead and confined work
- Anti-drip design and straightforward cleaning between colour changes
- Suited to paint, latex and varnish on renovation, furniture and small-area spraying
21V Lithium-Ion Cordless Spray Gun — MT Model
The MT model is our industrial-grade unit, with an upgraded brushless motor that raises spray pressure and flow rate for finer atomization. It is intended for large-area, high-demand spraying where film build and adhesion matter.
- 0–0.5 MPa adjustable pressure for controlled atomization on heavier coatings
- Multi-dimensional adjustment of flow rate, spray pattern and spray angle
- Uniform, full-bodied film with strong adhesion on prepared steel surfaces
- Anti-drip and anti-clog design with easy cleaning for extended site use
- Handles paint, latex, anti-rust paint, floor paint and industrial coatings

Where the Spray Guns Fit in Pipeline and Construction Work
On a threaded or welded pipe installation, the coating step is usually the last one before handover, and it is the step most often delayed by a missing compressor or a power point that is not there yet. A cordless gun lets the same crew that cut and threaded the pipe finish the surface protection in the same visit.
Typical work includes coating pipe supports, hangers, brackets and clamps; touching up cut ends and thread areas after assembly; recoating damaged galvanizing or shop primer; and spraying equipment frames, skids and access steel. The MT model suits runs of pipe and larger steel areas where film build and adhesion are specified; the Small Airplane model suits smaller areas, repairs and detail work.
Atomization, Pressure and Finish Control
Finish quality on site depends on atomization, flow and distance, not on the size of the machine. Our guns give the operator direct control over the variables that decide whether a coating lays flat or sags.
- Pressure: the MT model adjusts from 0 to 0.5 MPa, so heavier industrial coatings can be atomized at higher pressure and thin finishes at lower pressure
- Flow rate: adjustable on both models to match coating viscosity and the required wet film thickness
- Spray pattern: adjustable between a narrow pattern for edges and brackets and a wide pattern for flat plate and pipe runs
- Spray angle: multi-dimensional adjustment on the MT model for overhead, vertical and confined positions
- Film quality: even atomization produces a smooth, flat film without runs or orange peel, with strong adhesion on prepared steel
Battery Platform and Cordless Integration
Both spray guns run on 21V lithium-ion power, the same voltage class as the rest of our cordless line. That matters on a pipeline or fire-protection site where crews carry several tools to the same work front and want one charging routine rather than a separate power supply for each task.
Our Cordless Power Tools range covers drilling, cutting, grinding, punching and tightening alongside spraying, and it includes a Backpack Lithium Battery Pack for extended runtime where the work front is far from a charging point. We confirm the battery and charger configuration for each order when we prepare the proposal.
Configuration Options and Customization
We match the gun to the coating and the job rather than selling one specification for every site. Configuration is agreed before production and recorded on the order.
- Model selection between the Small Airplane and MT versions, or a mixed order for crews doing both detail and volume work
- Flow, pattern and pressure settings set for the coatings named in the project specification
- Battery and charger quantities sized to the number of guns and the shift pattern
- Carton and pallet configuration for the delivery destination, including mixed containers with pipe fabrication equipment
- Customized non-standard requirements reviewed against our tooling and production capability before quotation
Quality Control and Acceptance
Xinabo is a National High-tech Enterprise with more than 30 patents covering pipe connection and threading technology, and our production runs to a finished-product rate we hold at 99.9%. Spray guns are assembled and function-tested before packing, with atomization, trigger response, pressure adjustment and leak checks carried out on each unit.
Our conformity documentation includes attestation of conformity to the Machinery Directive and the Electromagnetic Compatibility Directive. Where a project requires specific documentation with the shipment, we confirm the document set during order review so it travels with the goods rather than following later.
Operation, Cleaning and Maintenance
Spray equipment lives or dies on cleaning discipline. The anti-drip and anti-clog design on both models keeps coating out of the air path during pauses, and the fluid path is arranged for quick flushing between colours and at the end of a shift.
- Flush the fluid path after each session and before any long shutdown
- Keep the nozzle and air cap clean; do not use metal tools that can deform the orifice
- Charge batteries in a dry, ventilated area away from solvent vapours
- Store guns with the fluid path clean and the trigger released
- Spare parts and replacement components are available through our after-sales channel

Frequently Asked Questions
Do Xinabo lithium-ion spray guns need an air compressor?
No. Both the Small Airplane and MT models use high-pressure atomization from a 21V brushless lithium-ion system, so no compressor, air hose or mains cable is required at the work face.
What is the difference between the Small Airplane model and the MT model?
The Small Airplane model is a lightweight portable gun for small-area spraying, renovation and touch-up work. The MT model is the industrial-grade version with an upgraded brushless motor, 0–0.5 MPa adjustable pressure, higher flow and finer atomization for large-area coating where film build and adhesion are specified.
Which coatings can be sprayed with these guns?
The range covers paint, latex and varnish on the Small Airplane model, and paint, latex, anti-rust paint, floor paint and general industrial coatings on the MT model. We confirm the setting for a specific coating from its type and viscosity when the order is configured.
Can the spray guns share batteries with other Xinabo cordless tools?
Our cordless range is built around 21V lithium-ion power and includes a backpack lithium battery pack for extended runtime. We confirm the exact battery and charger configuration for each order, including mixed orders with other cordless tools, when we prepare the proposal.
What documentation is supplied with the spray guns?
Our conformity documentation includes attestation of conformity to the Machinery Directive and the Electromagnetic Compatibility Directive. Where a project requires additional documents with the shipment, we agree the document set during order review.
How do we get a configuration and quotation?
Send the coating type, substrate, target finish, daily spray area, crew size and delivery destination. We use those inputs to select the model, set the adjustments, size the battery and charger package, and quote the delivery scope.
