2. SPRAY TIP SELECTION

Spray Tip and Pressure Selection

Spray Tips come in a variety of sizes for spraying a wide range of materials. Your sprayer includes a 515 Spray Tip for use with most paints on large surfaces such as walls and ceilings.

If you are spraying stains or need a different spray fan width, refer to the Spray Tip chart below to select the best Spray Tip for your project. Additional Spray Tip sizes are available from InoKraft.

Selection Criteria:

Material: The thicker the material, the larger Spray Tip Size you will need.
Spray Fan Width: Narrow spray fan for smaller projects; Wider spray fan for larger projects.
Sprayer Compatibility: Confirm your sprayer can be used with your Spray Tip size.

Tip Number Calculation:

The first digit is half of the fan width (e.g., #5 x 2 = 10 inch fan width). The last two digits are the size of the tip opening in thousandths of an inch.

Material	Spray Tip Size Range (for varying fan widths)	Sprayer Compatibility (Max Spray Tip Size)
Stain and Sealer	e.g., 209-609	MaXpray M1, MaXpray M3 Plus
Semi Transparent Stain	e.g., 211-611	MaXpray M1, MaXpray M3 Plus
Solid Stain	e.g., 211-613	MaXpray M1, MaXpray M3 Plus
Interior Paint/Primer	e.g., 313-715	MaXpray M1, MaXpray M3 Plus
Exterior Paint/Primer	e.g., 415-817	MaXpray M1, MaXpray M3 Plus

As spray tips wear, the hole size increases. Starting with a smaller hole size allows for longer use. Spray tips require periodic replacement to maintain consistent spray patterns and avoid clogs.
