Sigma airless paint sprayer is a high-pressure airless spraying equipment for painting, widely used in construction, renovation and coating projects. Our factory has rich manufacturing experience and strict quality control.

Our machines can spray latex paint, acrylic paint, enamel, primer, water-based coatings and other common coatings. Please check the product specification for viscosity requirements.

Sigma focuses on stable performance, cost-effective price and easy-to-source spare parts. We optimize the structure for convenient maintenance, and we provide customized service for our partners.

The model selection depends on your project scale and coating type. The spray tip is determined by paint viscosity and required spray width. You can send us your working condition, our sales team will recommend the suitable model and nozzle.

The maximum working pressure varies for different models, please refer to the technical data sheet of the specific model.

Our industrial grade models support long-time continuous operation for engineering sites. For heavy duty non-stop work, we recommend proper intermittent cooling.

Turn off the machine and release pressure completely first, then unscrew the tip guard, take out the old tip, install the new tip, and reassemble the guard. Always perform pressure relief before any operation.

Clean the pump system thoroughly after every use. Flush with suitable cleaning solvent according to your coating. Check filters, seals and hoses regularly.

1. Make sure there is enough paint material.
2. Check whether the prime valve is closed properly.
3. Inspect if the inlet filter is blocked.
4. Check wear of pump seals.

Most leakage issues are caused by worn seals or loose connections. Replace damaged sealing parts and tighten connectors.

Check power supply and power cable. Confirm the power switch is turned on. If the problem persists, contact our after‑sales support.

Standard warranty covers manufacturing defects for a specified period. Consumable parts such as seals, nozzles, filters are not covered by warranty. Please check the warranty card for full details.
