OP-1200A Heavy Duty Electric Airless Paint Sprayer Hydraulic Putty Wall Machine Large Power Spray Guns

The specification lists the power source as petrol/gasoline. Although the product name includes 'Electric', please confirm with the seller or product datasheet which drive option is supplied, as listings sometimes reference multiple variants.

The OP-1200A has a maximum operating pressure of 3600 psi, suitable for high-pressure, fast application on large jobs.

Nozzle sizes range from 0.021" to 0.047". Smaller tips (e.g., 0.021"–0.027") are best for thin coatings and fine finishes; mid-range tips suit primers and sealers; larger tips (e.g., 0.035"–0.047") are used for heavy coatings, putty, or fast coverage over large areas. Match tip size to material viscosity and desired finish.

Yes. The unit is rated for paint spraying and for applying putty on walls. For heavier materials like putty, use a larger tip, adjust pressure accordingly, and verify material is compatible with the pump and filters.

No cup required indicates the sprayer is an airless, direct-feed design that draws material from a separate container or bucket via a suction hose rather than a small on-gun cup.

Yes. The unit is described as industrial grade and designed for heavy-duty use, making it suitable for professional construction and large-area commercial projects.

Flush the pump, hose and gun after each use with the appropriate solvent or water depending on the material used. Regularly check and clean the inlet filter, pump filters, and replace worn tips and packings. Follow the manufacturer's maintenance schedule in the manual.

Wear appropriate PPE (respirator/mask, eye protection, gloves), ensure good ventilation, be aware of flammable fuels if using a petrol engine, relieve pressure before servicing, and follow local regulations for spray operations and solvent handling.

Included accessories vary by seller and package. Common accessories for airless sprayers include a spray gun, tips, suction hose, high-pressure hose, and filters. Check the specific listing or contact the seller for the exact accessories supplied.

Generally, airless sprayers can handle both water-based and oil-based coatings, but you should confirm material compatibility, clean thoroughly between different material types, and select the correct tip and pressure settings for each coating.

Typical priming involves placing the suction tube into the material container, opening the prime/flush valve (if fitted), running the pump at low speed to draw material until it flows solidly with no air, then purge air from the gun and gradually increase pressure to the working setting. Always follow the manufacturer's startup procedure in the manual.

Yes. The product specification lists OEM, ODM, and OBM support, so customization and private-label options are available—contact the manufacturer or supplier for details and minimum order requirements.

Warranty and after-sales support vary by seller and region. The listing does not specify warranty terms, so check the seller's warranty policy and service network before purchase.

Common causes include clogged tip or filter, worn tip, air in the suction line, or a worn pump packing. Stop work, relieve pressure, inspect and clean/replace filters and tips, check the suction hose for leaks, and consult the manual for pump maintenance steps. Contact the supplier if the problem persists.

It's ideal for painting walls and ceilings, applying putty on surfaces, large-area coverage for quick jobs, professional construction projects, and extensive home improvement tasks where high pressure and large flow are required.
