Titan gives a maximum recommended air volume for each PowrCoat, from 102 CFM on the 745 to 174 CFM on the 1064, and the PowrCoat series runs on air at up to 100 psi. Fluid pressure is the model's ratio times air pressure. Compare your compressor's rated delivery at working pressure to the CFM figure for your model, and confirm in the manual.
The two numbers Titan gives
A PowrCoat is an air-powered airless sprayer: a compressed-air motor strokes a piston fluid pump, so the compressor is part of the system. Titan publishes two air figures that matter when you are sizing one.
- Maximum recommended air volume, in CFM, for each model. This is the air the motor can use when it is working hard.
- Air requirement per gallon of output at 100 psi, in SCFM, which shows how air-hungry a model is for the paint it moves. Titan gives this figure for some models only.
Neither number is a compressor recommendation. Titan does not publish a minimum compressor horsepower or a tank size for the PowrCoat series in the data we hold, so this guide does not give one.
CFM by model
Titan air figures by PowrCoat model
| Model | Ratio | Max recommended air volume | Air per gallon of output at 100 psi |
|---|---|---|---|
| 630 | 30:1 | Not listed here | 25 SCFM per 4 L (Titan Australia data) |
| 730 | 30:1 | Not listed here | Not listed here |
| 745 | 45:1 | 102 CFM | Not listed here |
| 940 | 40:1 | 116 CFM | 36.4 SCFM |
| 960 | 60:1 | 128 CFM | Not listed here |
| 975 | 75:1 | 133 CFM | Not listed here |
| 1045 | 45:1 | 172 CFM | 43 SCFM |
| 1064 | 64:1 | 174 CFM | 57.7 SCFM |
| 1072 | 72:1 | Not listed here | About 65 SCFM |
Where a cell says not listed here, we do not have a confirmed figure for that model. Look it up in the operating manual for your unit or call (713) 931-0006.
Two patterns show in the figures Titan does publish. First, the three 10 in. air motor models (1045, 1064, 1072 on the diagrams) sit well above the 9 in. models: the 1045 lists 172 CFM against 116 CFM for the 940. Second, where Titan gives air per gallon, it rises as the ratio goes up. The 940 at 40:1 lists 36.4 SCFM, the 1045 at 45:1 lists 43, the 1064 at 64:1 lists 57.7 and the 1072 at 72:1 lists about 65. A higher ratio gets you more pressure from the same air line but you pay for it in air used per gallon sprayed.
Air pressure, ratio and fluid pressure
The ratio in a PowrCoat's name tells you how much the pump multiplies the air pressure. Fluid pressure equals the ratio times the air pressure at the motor. Titan's PowrCoat series page lists 100 psi as the maximum air pressure for the series, and its air-per-gallon figures are quoted at 100 psi.
Worked examples of ratio times air pressure
| Sprayer | Ratio | Air pressure | Fluid pressure |
|---|---|---|---|
| PowrCoat 940 | 40:1 | 100 psi | 4000 psi |
| PowrCoat 960 | 60:1 | 100 psi | 6000 psi |
| PowrCoat 630 | 30:1 | 116 psi | 3480 psi |
The 630 figure comes from Titan's Australian data, where 116 psi is the maximum air input. For all other models, check your manual.
The practical point is that fluid pressure follows the air pressure you set at the AirCare regulator. Turn the regulator down and fluid pressure falls by the ratio. Never turn it up past the rated limit to force a result. If you cannot reach the pressure you want at the regulator setting you expect, the air supply is the first thing to check, ahead of the pump. Our AirCare guide covers what is on that regulator.
Why the air must be clean and lubricated
Every PowrCoat carries Titan's AirCare system as standard: a filter, regulator and lubricator, with an automatically draining moisture trap. Titan says it eliminates motor icing. The filter cleans the air, the trap drains moisture out of it, and the lubricator feeds lubricant into the air stream for the motor. Titan's manual says the lubricator is factory-set and that you refill it with AirCare lubricant. It gives the proper rate as 1 drop per minute and says to increase it in humid weather, when icing may occur.
The CFM figure is the air the motor can use, so a compressor that delivers well below it cannot keep the motor supplied at heavy output. The answer is a compressor rated for your model's figure, not a higher regulator setting. The 940 AirCare page shows the parts of the unit.
Parts on the air inlet side
Air inlet and exhaust parts to know
Pages to open: the 1045 upper shroud for the 1045 to 1072 air plumbing, the 975 main assembly (shared in layout with the other 9 in. models) for the muffler, and the 630 upper shroud, which has its own air tubes and fittings. The whole family is indexed on the PowrCoat series parts page.
The air connection on the 940 is 3/4 in. NPT(M), taken from Titan's manual. We have not confirmed that size for other models, so check your manual before you buy hose fittings.
Check the compressor before you buy
Find your model's air volume
Use the table above, or the manual if your model shows not listed.
Read your compressor's delivery at working pressure
Use the rating at the pressure you will actually run, not the highest number on the label. Compare it to the CFM column.
Allow for the length of the air hose
Titan does not publish a maximum air hose length in the data we hold, so check the manual before you run a long hose.
Confirm with the manual or our parts team
The operating manual is the authority. Our manuals are on the manuals page, and (713) 931-0006 reaches the parts team.

The Short Version
Look up your model's maximum recommended air volume, compare it to your compressor's delivery at working pressure, and use the AirCare regulator to set fluid pressure. Never exceed 100 psi air pressure, or the limit in your own manual. Keep the AirCare moisture trap and lubricator working.
