A PowrCoat is an air-powered ratio pump. Titan lists 100 psi of air supply for each model, and the paint pressure is about that air pressure multiplied by the pump ratio: a 30:1 PowrCoat 730 is rated for 3000 psi, a 72:1 PowrCoat 1072 for 7250 psi. Pick the ratio for the pressure you need, then make sure the hose, gun and tip guard are rated at or above it.
What a ratio pump does
Electric and gas airless sprayers make pressure with a motor. A PowrCoat uses compressed air instead. Air pushes a large piston in the air motor, and that piston drives a much smaller piston in the fluid pump. Because the air side is bigger than the paint side, a small air pressure becomes a large paint pressure. The ratio is how much bigger.
Titan's model pages show the result in a table: air pressure 100 psi for every PowrCoat, a ratio for each model, and a maximum operating pressure. Read across the table and the pattern is clear. Paint pressure is roughly the air pressure times the ratio, and the last two digits of the model number match the ratio.
The seven PowrCoat models
PowrCoat models, ratio and maximum operating pressure (Titan model pages)
| Model | Ratio | Air pressure | Max operating pressure |
|---|---|---|---|
| PowrCoat 730 | 30:1 | 100 psi | 3000 psi |
| PowrCoat 745 | 45:1 | 100 psi | 4500 psi |
| PowrCoat 940 | 40:1 | 100 psi | 4000 psi |
| PowrCoat 960 | 60:1 | 100 psi | 6000 psi |
| PowrCoat 1045 | 45:1 | 100 psi | 4500 psi |
| PowrCoat 1064 | 64:1 | 100 psi | 6400 psi |
| PowrCoat 1072 | 72:1 | 100 psi | 7250 psi |
Figures are Titan's maximums. Titan's model pages give a maximum delivery for each model without a unit, so this guide does not quote per-model flow; check the page or manual for yours.
The 1072 rounds the pattern a little: 72 times 100 is 7200, and Titan lists 7250. Use the number on the model page, not the multiplication, when you are checking a rating.
What every PowrCoat includes
Titan's PowrCoat series page lists a flow range of 1.5 GPM to 6.0 GPM across the line, and a common build:
- A Severe Service fluid section with self-adjusting packings. Titan says Severe Service means twice the life with half the maintenance.
- A hard-chrome piston rod and cylinder.
- A high-capacity outlet filter.
- An air filter, moisture separator, regulator and lubricator for the air supply.
- 16 in. pneumatic tires and a hose rack for up to 200 feet of 1/2 in. hose.
Titan does not state a service life for the packings or other pump parts, so this guide does not either. The air-side items are worth knowing about because they are yours to look after: the filter, moisture separator and lubricator sit between your air supply and the air motor.
The air supply is part of the sprayer
A PowrCoat does not run without a compressed air supply, and the ratio only gives you the pressure in the table when the air pressure is there. How much air volume each model needs is in its manual, not here. Look that up before you buy a model.
Choosing a ratio
A higher ratio gives a higher maximum pressure. That is more pressure to work with, but it brings a rule you cannot skip: every component in the system must be rated for the pressure. A 6000 psi PowrCoat 960 with a hose or gun rated for less is a hazard, not a bargain.
Start from the job rather than the biggest number. Titan's series page does not tie a model to a particular coating, so check the coating's data sheet for the pressure and tip it needs. Then step up the table to the model whose maximum pressure covers the pressure you actually spray at.
Parts for air-powered sprayers
The main wear items are in the fluid pump assembly. Each model has its own page, and models do not all share part numbers, even when the pump has the same assembly number. On the site, the PowrCoat 730 and 940 fluid pump pages show the same pump assembly number, but the upper packing spring on the 730 is 155-906 while the 940 lists 182-906. The 745 and 960 pages list a different pump assembly, with the 182-906 spring.
PowrCoat 730 and 940 fluid pump examples
The PowrCoat 1072 pump is a different build with its own numbers: its fluid pump assembly page lists, among others, PTFE V-packing 0533663 and spring packing 0533697. The site also carries diagram pages for the PowrCoat 975, such as its fluid pump assembly. Always take the number from your model's page, never from a neighbour in the table.

The Short Version
Ratio times 100 psi of air is about the maximum paint pressure: 30:1 gives 3000 psi, 72:1 gives 7250 psi. Choose the lowest ratio that covers your job, make sure every hose, gun and tip guard is rated for it, and order pump parts from your own model's fluid pump page.
