Description
The DG-Tech 450 Airless Paint Sprayer is a powerful, high-end paint sprayer capable of imparting fine paint coverage at speed. It is powered by a strong 1800W motor and capable of pushing out high volumes of paint (flow rate of 2.5 L/min). The machine can be used for heavy-duty painting works on construction sites. Painting large outlets, exteriors and industrial paints equally requires application of the Machine; therefore, it is a painter's or contractor's choice.


Features

 :
  • 1800W Powerful Motor : Ensures dependable performance for continuous, high-volume spraying.
  • High Flow Rate (2.5L/min) : Does very big areas so fast that time for the job is less, and efficiency is high.
  • Adjustable Pressure Range (1000-3000 PSI) : Gives full control to apply to different materials and finishes.
  • 1/4" Hose Close Nipple : Hose connection suitable for standard hoses and accessories.
  • Standard Voltage: 220V~50Hz : Easily plugs into regular power outlets.
  • Airless Technology : Less overspray and finishes that are smooth.

Accessories

 :
  • High-Pressure Hose : The long, coiled blue hose that connects the sprayer unit to the gun.
  • Airless Spray Gun : The handheld device used to spray the paint, often including a trigger lock.
  • Spray Tip/Nozzle Guard : The red and silver part that attaches to the spray gun, which holds the reversible spray tip.
  • Suction Tube (or Inlet Tube) : The curved tube with a filter/screen on the end, used to draw paint from the container.
  • Primer/Drain Tube (or Return Tube) : The smaller, usually flexible tube used to prime the pump and return excess paint to the container.
  • Tip Wrench/Tool : The small yellow wrench or tool, used for maintenance or installing the spray tip.
  • Cleaning Cloth/Filter Element : The small piece of orange/yellow fabric (might be a filter or cleaning rag).
  • Pump Armor/Oil : The small bottle of liquid (usually an oil or lubricant for pump maintenance).

Applications

 :
  • Large-Scale Residential & Commercial Painting : Very good for very quickly covering walls, ceilings, and facades with paint or primer.
  • Industrial Coating Projects : High volume output for applying protective coatings for machinery, storage tanks, and structural steel.
  • Renovation & Construction : Make work faster in building construction, with even coverage and efficient application on a variety of surfaces.
  • Wood & Metal Surfaces : For application of finish, sealer, and protective coatings on doors, fences, and furniture.
  • Professional Painting Services : Essential equipment for the painter requiring quick work without compromising good finish and quality.

Usage 

Safety & preparation
  • Always wear PPE: eye protection or goggles, respirator or mask suitable for paint/solvent vapors, gloves, coveralls or protective clothing.
  • Operate in well-ventilated area to avoid inhaling fumes.
  • Treat the spray as high pressure: never point the nozzle/trigger at yourself or others. A high‑pressure jet can penetrate skin.
  • Before servicing or clearing blockages, always follow the pressure relief procedure (see below).
  • Ensure the electrical supply is safe: proper grounding, correct rated extension cable (if used), and stable supply voltage.
  • Only use coatings and solvents compatible with the pump materials (avoid solvents that chemically attack seals, aluminum parts, etc.).

Setup & priming
  • Position the sprayer unit on stable, level ground near your paint container.
  • Connect the suction (inlet) hose into the paint container (or use supplied suction tube).
  • Connect the high-pressure hose to the sprayer’s outlet and to the spray gun.
  • Install the spray tip (nozzle) in the gun and tighten securely.
  • Set the sprayer’s valve or control (some units have a prime/flush/operate selector) to the prime mode (or a low-pressure draw).
  • Turn on the machine (power ON) so that the pump draws paint through until paint appears at the gun (primed).
  • With gun locked or safety on, then gradually increase pressure via the pressure control knob until you get a good spray atomization. Do not immediately push to full pressure — find the lowest pressure that gives the needed finish.
  • Test the spray pattern on a scrap board or test surface. Adjust pressure or tip size if needed.

Spraying technique
  • Maintain a consistent distance from gun to surface (commonly 20–30 cm, but check with test pattern).
  • Keep the gun perpendicular to the surface and move in smooth strokes.
  • Use overlapping passes (often ~50% overlap) to ensure even coverage.
  • Start moving the gun first, then pull the trigger; release trigger just after leaving the surface (to avoid buildup at start/stop).
  • Avoid stopping mid‑stroke if possible — if you must, release trigger (i.e. stop spray) first, then reposition and resume.
  • If you see spitting or gaps, slow down or increase pressure slightly (within safe limits).
  • Do not exceed the design pressure or maximum tip size recommended (too much pressure or an oversize tip leads to wear, waste, poor finish).

Pressure relief before servicing
  • Before doing any cleaning, tip changes, hose disconnections, or maintenance:
  • Turn the sprayer off (power OFF).
  • Engage the gun’s safety lock (or lock the trigger).
  • Shift the sprayer valve (if present) to the “relief / prime / flush” position (i.e. open bypass).
  • Point the gun into a suitable waste bucket and trigger the gun (while locked to metal) to release residual pressure.
  • Only after confirming pressure is relieved (fluid has dribbled, no pressure buildup) should you open any couplings or disassemble parts.

Maintenance 

After every use (end of job / daily)
  • Flush the system immediately after finishing : Use the proper cleaning fluid/solvent for the paint type (water for latex/waterborne, mineral spirits or manufacturer‑recommended solvent for oil/solvent systems).
  • Remove the tip/nozzle (or at least retract it) and run fluid until clear (no paint) at the gun.
  • Open the prime/flush valve (if available) and allow fluid to circulate to flush internal passages.
  • Clean filters, strainers, and gun parts: remove and wash any inlet filter, gun filter, screen, or mesh.
  • Wipe down the exterior (hoses, body, gun) with solvent‑dampened cloth (not immersing the motor).
  • Inspect hoses, fittings, seals, O‑rings, connections for damage, leakage, wear. Replace any suspect parts.

Periodic / scheduled maintenance
  • Depending on use intensity, at weekly or after a certain number of hours:
  • Inspect or replace pump packing, O‑rings, gaskets, seals if showing wear or leakage.
  • Check and clean or replace valves (inlet/outlet), seats, check balls in the pump.
  • Replace worn spray tips / nozzles — a worn tip gives poor pattern, overspray, and inefficient use of paint.
  • For units with motor brushes: inspect brush length and wear. If brushes are low (per manufacturer spec), replace them.
  • Clean motor housing, vents, blow dust out (with compressed air, motor off).
  • Lubricate parts as recommended (e.g. packing gland or throats, if applicable).
  • Tighten any loose bolts, couplings, fittings, hose clamps.

Long-term storage
  • If you expect to leave the unit idle for days or weeks:
  • After final cleaning/flushing, run a small volume of a protective fluid (e.g. light oil or compatible preservative) through the pump and hose to coat internal metal surfaces, preventing corrosion or drying of seals.
  • Disconnect and store hoses, gun, and accessories separately in a clean, dry place.
  • Cap fluid inlets/outlets to prevent ingress of dust or moisture.
  • Periodically (once in a while) turn the sprayer on with minimal pressure and circulate the protective fluid (if possible) to keep internal parts from drying out.

Troubleshooting & tips
  • Weak pressure / poor spray: check for clogged filters, suction leaks, air ingress in suction line, worn pump seals, or low fluid in tank.
  • No paint flow: ensure suction hose is unobstructed, prime valve is open for suction, fluid viscosity is acceptable.
  • Irregular spray / mottling: dirty or clogged tip, worn tip, insufficient pressure, or bad gun seat.
  • Leaks: inspect and tighten fittings, replace worn seals.
  • Motor issues: check brushes, wiring, switch, power supply.
  • Always replace parts with correct, manufacturer‑specified spares.
