The Delta Spray HVLP spray gun was designed to produce the highest quality finish with today’s fluids as well as the Low V.O.C. (volatile organic compound) fluids of tomorrow.

This spray gun can spray most coatings or finishes currently being used for automotive, industrial, aero- space, marine, wood, plastic and architectural applica- tions, while easily operating from any paint delivery system, including cups, pressure pots, or remote pumps for production line operation.

The spray gun typically utilizes 40 psi (280 kPa, 2.8 bar) inbound air pressure to produce high quality paint finishes at 10 psi (70 kPa, 0.7 bar) atomizing air pres- sure.

The air regulator must have a minimum air flow capacity of 30 scfm at 100 psi (0.7 MPa, 7 bar) air pressure. Refer to the Pressure Drop Charts, page 11.
