The Titan MultiFinish 440 (model 0524029) is an electric air-assisted airless fine finish system with an onboard compressor, built on the Titan 440 airless platform. It is rated to 3300 psi, takes a tip up to 0.023 in. with one gun, uses a 7/8 HP PMDC motor, weighs 90 lbs, and also sprays standard airless.
What the MultiFinish 440 is
The MultiFinish 440 is Titan's electric air-assisted airless sprayer for fine finish work. It carries its own compressor, so you do not need a separate air compressor. Titan builds it on its 440 airless platform, which is why it can also spray as a plain airless unit when a job calls for it. The model number is 0524029, and the owner's manual is form 0524843P, on the manuals page with the other Titan fine finish manuals.
Air-assisted airless uses fluid pressure plus a small amount of air to atomize more finely than fluid pressure alone. If you are new to that idea, the short version is that you get a finer pattern from a small tip without cranking pressure to the limit.

We do not list maximum delivery or maximum air pressure here. Published sources disagree on both, so read them from the data plate or the manual for your unit.
The 3300 psi figure matters beyond the spec sheet. Titan's manual says every replacement part or accessory, including the tip, guard, gun, extension, fitting and hose, must be rated at least 3300 psi. The GM 3600 gun is rated higher, but on this machine the lowest rating in the system governs.
Two modes: MultiFinish and airless
Titan's manual describes two ways to run the machine. These figures come from a manual excerpt that we could read from a single source, so treat them as the manual's guidance and check them against your own copy.
- Airless mode. Pump pressure from 500 to 3300 psi. This is the standard airless setup.
- MultiFinish mode. Low-pressure fine finish spraying, with a recommended pump pressure of up to 1000 psi. To start, set the pressure control knob so the fluid gauge reads about 400 psi. The air regulator controls the atomizing air. Titan's advice is to use the lowest pressure that atomizes well.
Poor atomization usually traces back to a worn or oversized tip, air pressure set too low, insufficient fluid delivery or material that is too thick, according to the manual's troubleshooting page. Check the tip first.
Features Titan names
These are Titan's own descriptions, repeated by dealers, and we pass them on as stated rather than as our own testing.
- Quad+ Packings. Titan states they prevent damage to the piston and seals.
- AutoOiler. Titan states it lubricates the packings automatically.
- Sureflo Pusher Valve. A stuck valve can be released with it.
- PermaLife Cylinder. Titan describes it as needing no replacement.
- Rapid Clean. Set the pressure knob to RAPID CLEAN to clean the pump completely.
- Electronic pressure control and a quiet onboard compressor with air relief.
Titan does not publish a service life in hours or gallons for the packings or the compressor, and we have not found service intervals for this model, so follow the manual and replace on symptoms.
Coatings and use
Titan and its dealers list stains, lacquers, enamels, latex and other low to medium viscosity coatings, with minimal or no reduction. The tip ceiling of 0.023 in. keeps it in fine finish territory rather than heavy-build production work. As with any airless-based sprayer, strain and stir the coating first, thin only as the coating maker allows, and flush the machine after each job.
