VMAC 6-in-1 Multifunction Power System (Cat)
By VMAC
The VMAC Multifunction Power System, powered by a Tier 4F Cat Industrial Diesel Engine, includes six power sources in one compact, quiet system. With noise reduction panels, low and high idle controls, and Standby Mode, operators can safely communicate while working without disturbing the job site or the neighbors.
| Air Compressor | 45 CFM @ 100 psi (175 psi max); VMAC oil-injected rotary screw; 100% duty cycle; belt-driven |
|---|---|
| Engine | Cat C1.1 industrial diesel engine Inline 3, 4-stroke; naturally aspirated 3,400 RPM, Tier 4 Final |
| Weight (dry) | Approximately 710 lb (322 kg) |
| Dimensions | 34.8” (l) x 24.8” (w)* x 31.3” (h); 88.4 cm (l) x 63 cm (w) x 79.5 cm (h) Base footprint: 34.5” (l) x 19.5” (w); 87.6 cm (l) x 49.5 cm (w); *29.75” (75.6 cm) w/ radiator sound deflector |
| Decibels (dB) @ 21 feet (6.4 meters) | 74.25 dB at high idle, 69.75 dB at low idle, 0 dB in Standby Mode |
| AC/DC Generator/Welder | AC: 8 kW output (w/ terminal strip) 1 x 30 A, 240V, 60 Hz three phase circuit; 1 x 30 A, 240V, 60 Hz single phase circuit; 2 x 20 A, 120V, 60 Hz single phase circuit; DC: For battery boosting/charging; other DC loads Boost – 300 A max @ 13V; Charge – 100 A max @ 12V, 24V; CC mode for SMAW and GTAW (stick/TIG welding); 250 A @ 35% duty cycle; 190 A @ 60% duty cycle |
| Power Take-off Port | Clutched SAE ‘A’ port with 9-toothed spline, 2,800 RPM output, 35 lb-ft continuous torque max (patented) |
| Hydraulic Pump (optional) | 5 GPM, 8 GPM or 10 GPM @ 3,500 psi (max) |
| Battery | ACDelco 12V, 460 CCA, 575 CA |
| Control System | Remote mounted control/digital display box with electronic key switch and LCD for compressor on/off controls, observing system status, and adjusting parameters; Remote mounted generator/welder control box with genset voltage meter and selector, welding current and ARC force control; Socket for optional remote welding control; Integrated voltage sensing interlock feature ensures safe welding/battery boosting and protects equipment by disabling the genset in unsafe conditions; Separate selector switches engage compressor, generator and PTO; any function or all three can be selected at any time; Multi-speed throttle control responds to operating function and air demand; With compressor-only selected, and sustained periods of no air use, the control system will shut down the engine (Standby Mode); the engine will not shut down automatically with generator selected |
| Cold Climate Protection | Cold climate kit for ambient temperatures below -10°C (14°F); Optional 1,750 W power inverter allows cold climate kit to engage on the way to the job site; Engine and compressor wait until the system temperatures are above 41°F (5°C) before loading and going into a running state; Engine automatically restarts when system temperature falls below 23°F (-5°C); Small heat strip included in LCD Digital Control Box; Battery jump start connections are recommended to be tied into the truck batteries in locations where extreme cold is expected; it is not necessary in mild climates |
| Fuel Supply Options | 7-gallon tank with fuel gauge and low fuel shut-off sensor; External Diesel Fuel Pump Kit |
| Air Receiver Tank | Minimum 10-gallon air receiver tank recommended (not included) for proper operation of all functions |
| Warranty | Two years on all major components; VMAC air-ends are covered by VMAC’s Lifetime Warranty (Limited); Cat engine covered by Caterpillar’s 2-year Limited Warranty; For more information about warranty policies, visit www.vmacair.com/warranty |
