SPEEFLO Commander Parts Overview
The supplied page is a machine-family category hub rather than a single exploded diagram. Titan documentation separates Commander equipment into portable heavy-duty-cart models and wall-mount or drum-mount models, then provides dedicated exploded sections for the 742-555 and 742-557 air motors, five fluid-pump families, air assembly 928-513, heavy-duty cart, pump mounts, wall bracket, outlet filtration, siphon hoses, bleed systems and gun manifolds.
Documented portable models include 721-443, 731-441, 741-440, 761-411 and 761-461. Documented wall or drum models include 721-532, 721-354, 731-331, 731-431, 731-183, 741-331 and 761-301.
Functions Supported by Commander Assemblies
Pneumatic Drive
The 742-555 or 742-557 air motor converts compressed-air energy into reciprocating pump motion.
Material Pressurization
The selected fluid-pump assembly draws coating and generates the high-pressure fluid output required for airless spraying.
Air Preparation
Air assembly 928-513 regulates and conditions incoming compressed air for the Commander drive system.
Fluid Delivery and Control
Outlet, filter, siphon, bleed and manifold assemblies manage pickup, filtration, delivery, pressure release and gun distribution.
Service Applications
Use this hub for preventive maintenance, pressure-loss diagnosis, pump repair, air-motor servicing, filter restoration, material-pickup repairs, bleed-system work, cart or mounting repairs, multi-gun system planning and model-specific parts purchasing for professional and industrial Commander installations.

Commander Parts Buying Guide
1. Record the full model
Use the complete Commander model number and do not rely on the family name alone.
2. Confirm mounting style
Determine whether the unit is portable, wall mounted or drum mounted.
3. Identify the pressure ratio
Portable and stationary configurations use different 20:1, 30:1, 40:1, 45:1 and 60:1 combinations.
4. Match the assembly
Use the air-motor, fluid-pump, filter, bleed, siphon, cart or mount number shown on the equipment or diagram.
Commander Maintenance
Relieve pressure before service, inspect grounded high-pressure hoses before each use, keep the assigned outlet filter clean, verify secure air and fluid connections, and maintain moisture-free air to the 742-series motor. Titan recommends a water trap and identifies motor inspection intervals of 1,500 service hours for non-circulating models and 800 hours for circulating models.
Commander Repair Planning
Document the model, ratio, mounting configuration, air-motor number, fluid-pump number, outlet-filter type and observed symptom. Inspect connected systems before replacing a complete assembly because pressure, priming and cycling problems may originate in air preparation, material pickup, filtration, pump valves or the pressure-relief path.

SPEEFLO Commander Parts FAQs
What type of page is the SPEEFLO Commander Air Powered Airless Sprayer page?
It is a machine-family replacement-parts hub. It organizes portable, wall-mount, drum-mount, air-motor, fluid-pump, air-control, cart, mounting, outlet, filtration, bleed, manifold and accessory categories for Commander systems.
Which Commander models are documented as portable units?
Titan identifies portable heavy-duty-cart models 721-443, 731-441, 741-440, 761-411 and 761-461 in 20:1, 30:1, 40:1 and 60:1 configurations.
Which Commander models are documented as wall or drum mounted?
Titan identifies 721-532, 721-354, 731-331, 731-431, 731-183, 741-331 and 761-301 across drum-mount and wall-mount arrangements.
Which air motors are used in the Commander family?
Titan’s Commander documentation identifies air motors 742-555 and 742-557. The correct motor depends on the complete sprayer model and motor-pump configuration.
Which fluid-pump assemblies belong to the Commander family?
The live Commander hub provides dedicated categories for 140-556, 155-559, 181-556, 185-551 and 245-555 fluid-pump assemblies.
What is the Commander 928-513 air assembly?
Titan identifies 928-513 as the 3/4-inch air assembly used across documented portable and stationary Commander configurations.
Which outlet filters are documented for Commander systems?
Titan documents several configuration-specific outlet filters, including 920-554, 920-556, 920-605 and 920-610. Match the filter to the complete model and mounting arrangement.
What should be inspected when a Commander loses spray pressure?
Diagnose the air supply, assigned air assembly, fluid pump, siphon path, outlet assembly and outlet filter before replacing parts. A pressure symptom can originate in more than one subsystem.
What should be checked when a Commander will not prime?
After relieving pressure, inspect the model-specific siphon hose and rock catcher for blockage, leakage or loose connections, then inspect the matched fluid-pump inlet components.
How should pressure be relieved before Commander service?
Lock the gun trigger, shut off the pump and use the applicable PRIME/SPRAY or pressure-bleed control according to Titan’s pressure-relief procedure before opening any pressurized connection.
How should the 742-series Commander air motor be maintained?
Titan recommends moisture-free air, inspection at the documented service interval and appropriate air-motor service kits. A water trap is recommended, with additional moisture separation or automatic oiling where conditions require it.
What information should be used to order Commander parts?
Use the complete sprayer model, mounting style, pressure ratio, assembly number, individual part number and operating symptom. Do not order from the Commander name alone.
Locate the Correct Commander Assembly Before Ordering
Use the machine-family hub to move from the complete sprayer identification to the exact exploded assembly and part number. This reduces mismatched pump, motor, filter, hose and mounting orders.
