Apollo Needle & Nozzle Options for 7500 and 7700 Atomizer Gun

Many spraying difficulties are the result of using incorrect size needles, nozzles and air caps.

The chart below shows you which needle and nozzle combination to use for various applications. The maximum viscosity measured with a Zahn #2 cup is also shown.

Save over individual price parts by purchasing Needle & Nozzle Sets, or Spray Kits.

Up to four sets of nozzles and needles can be stored in the Atomizer Deluxe Carrying Case which is supplied with the gun.

      AP7541HS Professional High-Solids Atomizing Set
      Apollo's professional high-solids atomizing set is the perfect addition to the 7500/7700 spray guns for those  who want to spray high-solids paints or clear finishes.

The B-HS air cap when paired with the 1.3mm and 1.5mm nozzles is perfect for spraying high-solids wood coatings. The C-HS cap when paired with the 1.8 or 2.0mm nozzles is perfect for spraying latex paint on walls and doors. For spraying latex on cabinets we recommend the 1.5mm with B-HS cap for smoother results. All needles and nozzles are made of stainless steel and all air caps are made of aluminium and anodized for easy identification and additional protection against solvents.
