Start with gun count: the 4900 Plus runs up to three guns, the 6900 Plus four, the 8900 Plus five and the 12000 Plus six. Then check the coating, since Titan lists the DI models for very heavy coatings including drywall mud. Gas gives more flow; electric needs a 20 amp outlet and a short cord.
1. How many guns will you run?
Gun count sets the pump size more than anything else, and the maximum tip falls each time you add a gun. These are the figures Titan's product pages and the Plus manual give for the gas models:
Gas PowrTwin Plus: guns and tip limits
| Model | Guns | Max tip, 3 guns | Max tip, 4 guns | Max tip, 5 guns |
|---|---|---|---|---|
| 4900 Plus | Up to 3 | 0.022 in. | - | - |
| 6900 Plus and 6900 Plus DI | Up to 4 | 0.023 in. | 0.019 in. | - |
| 8900 Plus | Up to 5 | 0.032 in. | 0.028 in. | 0.024 in. |
| 12000 Plus and 12000 Plus DI | Up to 6 | 0.034 in. | 0.030 in. | 0.026 in. |
Gun counts and 3, 4 and 5-gun tips are from Titan's pages. One-gun and two-gun limits are left out where Titan's page and its manuals disagree. Never exceed the maximum tip for your gun count.
Work backwards: pick the tip your coating needs (question 2), then find the smallest pump whose limit allows that tip at your gun count. Running several guns also needs a manifold on the single gun outlet, with unused outlets plugged. The 12000 Plus manifold page shows what those optional assemblies contain.
2. What are you spraying?
For the standard Plus pumps, Titan lists stains, lacquers, epoxies, enamels, elastomeric, latex, dry fall and block fillers. Titan's page for the DI models adds very heavy coatings including drywall mud, and says the DI line has a submersed foot valve for heavy material. The Plus manual's tip chart (fan widths 8 to 12 in.) shows how orifice size climbs with thickness:
- Varnish and lacquer: 0.009 in. to 0.011 in.
- Stains: 0.011 in. to 0.013 in.; solid stains and house paints: 0.013 in. to 0.017 in.
- Primers and commercial architectural coatings: 0.017 in. to 0.019 in.
- Dry fall and one-coat paints: 0.019 in. to 0.023 in.
- Elastomerics: 0.021 in. to 0.031 in.; block filler: 0.025 in. to 0.031 in.
Compare that with the table above. Elastomeric or block filler through a 0.031 in. tip fits the 8900 Plus on three guns (0.032 in.) but not the 6900 Plus on three guns (0.023 in.). For heavy material, also choose the filter by coating: the site lists 930-005 (5 mesh) for heavy materials and 930-004 (0 mesh) for mastics, against 930-006 (50 mesh) for latex and normal architectural coatings.
3. Gas or electric?
Electric versions deliver less flow. Titan lists the 4900 Plus at 1.50 gpm (5.7 L/min) gas and 1.10 gpm (4.2 L/min) electric, and the 6900 Plus electric at 1.25 gpm (4.7 L/min). Titan's pages give the electric motor as 2 HP DC. The site carries the 6900 Plus electric and the 6900 Plus DI electric as complete units, and Titan says a PowrTwin can be converted between gas and electric with a Convertokit sold separately. Pick gas where there is no power, and electric where there is a suitable outlet.
4. What power is on the site?
Both manuals ask for a 20 amp service outlet for electric models. They advise placing the sprayer within 10 to 15 feet of the outlet with a short cord and a long paint hose, and if you need an extension cord, using only a grounded 3-wire #12 cord. After an overload, turn off the sprayer, relieve pressure, wait about 30 minutes and push in the reset button. Gas engines must be fuelled and run outdoors or in ventilated areas, away from ignition sources.
5. Do your hose and gun suit it?
Every hose, gun, tip guard and fitting must be rated at or above the sprayer's maximum pressure, and the hose must be airless-rated and grounded. The manual asks for at least 50 ft of nylon airless hose. Titan's pages list what ships with the gas units: an RX-Pro gun, 517 tip and 1/4 in. x 50 ft hose for the 4900, 6900 and 8900 Plus; an RX-Apex Non-Filter gun, 517 tip and 1/4 in. x 50 ft hose for the 12000 Plus; and the same gun with a 3/8 in. x 50 ft hose for both DI models. Check that against the order before you buy a second set.
6. What will you need to keep it running?
Budget the consumables when you choose the model, not afterwards. Titan's manual makes Coolflo mandatory in the hydraulic system and says not to use anything else, and it asks for a fluid and external hydraulic filter change every twelve months. Daily, the packing oil cup is filled half full with Piston Lube.
- 430-361 Coolflo by the gallon and 430-362 by the quart.
- 314-480 Piston Lube.
- 451-220 hydraulic filter, the one the 6900 Plus hydraulic system diagram lists.
- 451-210 complete DI fluid section (6900 Plus DI) and 236-024 (12000 Plus DI), if you want to know what a full replacement is.
Manuals for each model are on our manuals page.
Confirm the exact model
Titan's lineup covers gas and electric Plus and DI versions, and the site also has diagrams for older XLT and GH generations. Read the model and serial number from the sprayer, then use the gas or electric PowrTwin parts page to reach the diagram. If you are buying and still unsure between two sizes, call (713) 931-0006 with your gun count and coating.

The Short Version
Gun count and the tip your coating needs pick the pump size, the coating decides between standard Plus and DI, and your site decides gas or electric. Confirm the model and serial number before you order parts.
