Match the tip orifice to the coating: Titan's Plus manual chart runs from 0.009" to 0.011" for varnish and lacquer up to 0.025" to 0.031" for block filler. Match the manifold filter mesh too: 930-006 (50 mesh) for latex, 930-007 (100 mesh) for fine materials, 930-005 (5 mesh) for heavy materials. Never exceed your sprayer's maximum tip for the number of guns.
The tip sets the flow
A PowrTwin is a high-volume hydraulic-drive sprayer, but the tip is still what decides how much coating leaves the gun and how wide the pattern is. The orifice size controls delivery. The fan angle controls width. Thicker coatings generally need a larger orifice; fine finishes use a smaller one.
A tip also wears. A worn tip has a wider orifice, so pressure falls, the pattern turns coarse or streaky and more paint is used. If the pattern has degraded and the filters are clean, change the tip before you suspect the pump. Titan's manual adds that extra pressure also wears tips faster and adds overspray, so set pressure only as high as it takes to atomise.
Orifice ranges by coating
Titan's PowrTwin Plus manual gives a chart of orifice ranges by material. The chart is based on fan widths of 8 to 12 in. Treat the ranges as a starting point and check the coating maker's data sheet for the coating you are spraying.
Orifice range by coating (Plus manual chart, 8 to 12 in. fan)
| Coating | Orifice range |
|---|---|
| Varnish and lacquer | 0.009" to 0.011" |
| Stains | 0.011" to 0.013" |
| Solid stains and house paints | 0.013" to 0.017" |
| Primers | 0.017" to 0.019" |
| Commercial architectural coatings | 0.017" to 0.019" |
| Dry fall and one-coat paints | 0.019" to 0.023" |
| Elastomerics | 0.021" to 0.031" |
| Block filler | 0.025" to 0.031" |
The DI manual's chart agrees in spirit. Titan's own tip numbers are not listed here; your manual and the tip packaging give the tip designations.
Maximum tip by gun count
A PowrTwin pump delivers a fixed volume. Split that flow between more guns and each gun gets less, so the largest tip you can run falls with every gun you add. Titan lists the limits per model. Never exceed the maximum tip size for the number of guns you are running.
Maximum tip by number of guns (Titan's figures for gas Plus models)
| Guns | 6900 Plus | 8900 Plus | 12000 Plus |
|---|---|---|---|
| 1 | 0.050" | 0.054" | check your manual |
| 2 | check your manual | 0.038" | 0.040" |
| 3 | 0.023" | 0.032" | 0.034" |
| 4 | 0.019" | 0.028" | 0.030" |
| 5 | - | 0.024" | 0.026" |
Titan's published figures for a few cells conflict between its product pages and its manuals, so those cells point you to your manual. The 4900 Plus runs up to three guns, with a 0.022" maximum tip at three guns.
This is one reason the chart matters when you add a gun. Elastomerics at 0.021" to 0.031" is within the 8900's limits on one or two guns, but on four guns the 8900's limit is 0.028" and on five guns 0.024", so check the chart against the gun count before you start. Our guide to running multiple guns covers manifolds and hose.
Matching the manifold filter
The PowrTwin's high-pressure filter takes a manifold filter insert, and the mesh should match what you are spraying. The finer the mesh, the more it can stop. A mesh that is too fine for a heavy coating clogs; one that is too coarse for a fine finish lets particles through to the tip. The site lists four, all shown on the Plus 6900 and Plus 8900 high-pressure filter pages:
PowrTwin manifold filter inserts
| Part | Mesh | Use it for |
|---|---|---|
| 930-007 | 100 mesh | Stains, lacquers and other fine material |
| 930-006 | 50 mesh | Latex and normal architectural coatings; also the standard insert |
| 930-005 | 5 mesh | Heavy materials |
| 930-004 | 0 mesh | Mastics |
The manuals add that a partly blocked filter causes pressure loss and pulsing, and that the filter element is cleaned from the inside out. The inlet screen 0509762A is a different filter, at the siphon hose. The Plus 8900 accessories page lists the manifold filters together: 8900 Plus accessories.
Clogs and wear
- For a clogged reversible tip, rotate it 180 degrees and trigger once. Never make more than one trigger pull with the tip reversed.
- Lock the gun and relieve pressure before you change a tip, and never run without a tip guard.
- If the pattern shows tails or an hourglass, the manual points to inadequate delivery. A round pattern points to a worn tip or fluid that is too heavy.
- If the sprayer surges, look for a suction leak or pulsating delivery before you change the tip.
Titan's 538072 RX-Apex gun fits the PowrTwin 4900, 6900, 8900 and 12000, and is shown on the accessories pages. Check which tip and guard your gun takes against the gun's own instructions.

The Short Version
Pick the orifice from the coating chart, pick the mesh to match, and check the maximum tip for the number of guns before you go above one. Change a worn tip before blaming the pump.
