QAS 700 VD T4F – 700 kVA Mobile Generator

Manufacturer: Atlas Copco | Models: QAS 700 VD T4F (Multi-Voltage, Tier 4 Final)

Overview

The Atlas Copco QAS 700 VD T4F is a high-capacity, multi-voltage, Tier 4 Final mobile generator engineered for rental, industrial, utility, and mission-critical applications requiring dependable 24/7 prime power. Powered by a rugged Volvo T4F 16-liter engine, this generator delivers 700 kVA / 560 kW of prime power at 480V with exceptional fuel efficiency, low noise performance, and best-in-class serviceability.

Built inside a heavy-duty, sound-attenuated enclosure with 110% fluid containment, the QAS 700 includes Atlas Copco’s Premium Rental Specification, allowing up to 32 generators to run in parallel using Power Management System (PMS) technology. A four-position voltage selector switch, large onboard 707-gallon fuel tank, RACOR dual fuel filtration, 1600A main breaker, and robust cam-lock distribution make this the preferred solution for large job sites, plant shutdowns, events, and temporary power installations.
