Selecting the Proper Needle/Nozzle Kit

The spray gun’s needle/nozzle kits range in size to provide different fluid flow rates.

As a general guideline, use the fluid nozzle that will give the required flow with the needle fully triggered at the lowest fluid pressure.

For low flow rates or light viscosity fluid, select the smaller nozzle sizes.

For high flow rates or high viscosity fluid, select the larger nozzle sizes.

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, aerospace, marine, wood, plastic and architectural applications, 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 pressure.

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.

D

Ventilate the Spray Booth

WARNING

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth.

Do not operate the spray gun unless ventilation fans are operating.

Check and follow all of the National,

State and Local codes regarding air exhaust velocity requirements.

Check and follow all local safety and fire codes.

Setup

1. Connect the Air Line

NOTE:

D You must install an air pressure regulator (F) on the gun air line to control air pressure to the gun. See

Fig. 2.

D

If your regulated air source does not have a filter, install an air filter (G) on the air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your finished workpiece.

See Fig. 2.

D Use a 5/16 inch (7.9 mm) I.D. air hose to minimize excessive pressure drop in the hose. See the

Pressure Drop Chart on page 11 for the expected pressure drops through a 25 ft. (7.625 m) hose.

2. Connect the Fluid Hose

NOTE:

D Before connecting the fluid line, blow it out with air and flush it with solvent. Use solvent which is compatible with the fluid to be sprayed.

D Install a fluid regulator (L) on the fluid line to control fluid pressure to the gun. See Fig. 4.

D Filter the fluid line of coarse particles and sediment to avoid clogging the fluid nozzle and causing finishing defects.

Setup

3. Flush the Spray Gun.

Before putting any paint through the spray gun, flush the gun out with a solvent that is compatible with the fluid to be sprayed, using the lowest possible fluid pressure and a grounded metal container.

6. Adjust the Spray Pattern

WARNING

COMPONENT RUPTURE HAZARD

Do not exceed the 100 psi (0.7 MPa,

7 bar) maximum fluid and air pres-

sure of this gun. Higher pressures can cause parts to rupture and result in serious injury.

Follow these steps to establish the correct fluid flow and air flow:

A. Turn the fluid adjustment knob (21) counterclockwise until no restriction of the trigger movement is felt, then turn out another half turn. When the knob is turned far enough, the trigger should be able to touch the gun handle when the gun is triggered.

7035A

Fig. 5

WARNING

PRESSURIZED EQUIPMENT HAZARD

To reduce the risk of a serious injury whenever you are instructed to relieve pressure, follow the Pres-

sure Relief Procedure on page 12.

4. Relieve the Pressure.

5. Position the Air Cap

Rotate the air cap as needed to achieve the desired spray pattern direction. To create a round pattern, turn the pattern air off by turning the pattern adjustment knob (13a) fully clockwise. Refer to Fig. 12, page 11.

6. Adjust the Spray Pattern (continued)

B. Adjust the fluid flow using the fluid pressure regulator (L) installed in the gun fluid line. Typical industrial flow rates will vary with regulator pressures from 5 to 30 psi (34 to 210 kPa, 0.3 to

2.1 bar).

Setup

NOTE: A larger fluid nozzle at a reduced fluid pressure will maintain the same flow rate, but slow down the fluid stream (velocity). When air is applied, this allows the air to act on the fluid longer and improve the atomization.

D. If further fluid flow restriction is needed at the gun, turn the fluid adjustment knob (21) clockwise to reduce the volume of fluid output by limiting the needle travel.

WARNING

PRESSURIZED EQUIPMENT HAZARD

To reduce the risk of an injury from accidental spray from the gun, do not remove the fluid adjustment knob (8) while the gun is pressurized with air and fluid. Follow the Pressure Relief Procedure on page 12.

7038A

CAUTION

Restricting the trigger and fluid needle travel by continuously spraying with the fluid adjustment knob closed (turned clockwise), will cause accelerated abrasive wear on the fluid needle and wear on the trigger/air valve shaft interface.

For the best results, use the gun fluid regulator to adjust the fluid flow or use a different size needle/ nozzle/air cap combination.

10 308741

Setup

6. Adjust the Spray Pattern (continued)

NOTE:

D

If the fluid adjustment knob is turned in all the way the gun will emit only air.

D

For continuous spraying, turn the fluid adjustment knob (8) counterclockwise until no restriction of the trigger movement is felt. When the knob is turned out far enough, the trigger should be able to touch the gun handle when the gun is triggered. For the typical fluid adjustment knob setting, turn the knob out 1/2 turn more. This setting provides maximum fluid flow and prevents premature wear on the fluid nozzle.

E. Open the pattern adjustment valve (25) by turning the knob fully counterclockwise to achieve a full fan pattern.

F. Using the air pressure regulator (F), set the air supply pressure at about 50 psi (345 kPa, 3.4 bar).

See the Pressure Drop Chart for regulator setting versus gun inlet pressure comparison.

If available, use the fluid manufacturer’s recommendations to set the air line pressure for a high volume, low pressure, spray gun application.

NOTE: Local laws may limit the maximum pressure to 10 psi (70 kPa, 0.7 bar) at the air cap for

HVLP compliance. The accessory Air Cap Verification Kit is available to measure the atomizing pressure at the air cap.

G. Test the spray pattern and atomization while holding the gun about 6 to 8 inches (150 to 200 mm) from the test piece.

H. If the spray pattern is too wide with the pattern adjustment knob (13a) turned fully counterclockwise, turn the pattern adjustment knob clockwise until you have the desired pattern size.

NOTE: T urning the pattern adjustment knob fully clockwise will produce a round pattern.

I.

Check the atomization quality again. Increase the gun air supply pressure with the air pressure regulator in 5 psi (34 kPa, 0.3 bar) increments until you obtain the desired atomization.

J.

If after increasing the gun air supply pressure the atomization is still unacceptable, try installing a larger fluid nozzle size to reduce the fluid velocity.

Refer to Fig. 10. Repeat steps 6-E to 6-I until you obtain the desired atomization.

308741 11

Operation

Applying the Fluid Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Proce-

dure whenever you:

D are instructed to relieve the pressure,

D stop spraying,

D check or service any of the system equipment,

D or install or clean the spray nozzle.

1.

Turn off the air and fluid supply to the gun.

2.

Trigger the gun into a grounded metal waste container to relieve air and fluid pressure.

When using the HVLP spray gun, instead of a conventional air spray gun, you may need to use a slightly slower hand movement and make fewer passes with the gun to coat a part. This is due to the reduced spray velocity produced by lower HVLP air pressures, along with a larger fluid particle size because there is less air to blow off solvents than what is produced by conventional air spray. Take care to avoid runs or sags as you spray.

1.

To achieve the best results when applying fluid, keep the gun perpendicular to the surface and maintain a consistent distance of approximately 6 to 8 inches (150 to 200 mm) from the object being sprayed. See Fig. 14.

2.

To obtain an even finish, use smooth, even strokes across the object being sprayed with 50% overlap.

3.

Paint using parallel strokes. This spray gun applies all coatings evenly without cross coating.

Troubleshooting

WARNING

PRESSURIZED EQUIPMENT HAZARD

To reduce the risk of a serious injury, follow the Pres-

sure Relief Procedure on page 12 before checking or repairing any part of the gun or system.

PROBLEM CAUSE

Fluid flow is fluttering while spraying 1.

Fluid nozzle not tight enough

Fluid flow fades while spraying high viscosity fluids

SOLUTION

1.

Tighten fluid nozzle to 125–135 in-lb (14–15 N S m).

3.

Check fluid filter.

2.

Fluid filter clogged

4.

Fluid adjustment knob not properly set

2.

Fluid pressure too low, causing fluid flow to reduce when gun is elevated

5.

Turn the fluid adjustment knob out for less feathering or use a larger size nozzle.

1.

Air hose size is too restricted for higher air flow being used

1.

Use 5/16 in. (7.9 mm) I.D. air hose if the hose is 25 ft.

(7.625 m) long. If longer hose is needed, use a 3/8 in. (9.5 mm)

I.D. hose.

3.

Raise fluid pressure at source or use a smaller fluid nozzle.

Pattern becomes off-set or heavy on ends

Gun fluid pressure is too high with gun triggered

Using a low fluid pressure setting, the fluid flow is too high, making it necessary to restrict needle travel to reduce fluid flow

Fluid system will not operate at low enough fluid pressure [below 10 psi

(70 kPa, 0.7 bar)]

Air cap horn holes plugged or damaged

Using needle/nozzle kit with too small orifice

Using needle/nozzle kit with too large orifice

There is no fluid regulator, or air regulator on pressure pot is not sensitive enough at low pressures

Clean air cap horn holes with nonmetallic item such as a toothpick, or replace air cap.

Use needle/nozzle kit with larger orifice

Use needle/nozzle kit with smaller orifice

Add low pressure fluid regulator, or add more sensitive low pressure air regulator on pressure pot.
