Sunbelt Rentals’ 100 kW AirPac mobile generator package has become one of the quiet, behind-the-scenes workhorses of the US rental market, supplying temporary power for construction sites, film shoots and outdoor events that cannot afford outages.

What the Sunbelt AirPac 100 kW is built to do

The AirPac 100 kW is a towable, diesel-driven generator that Sunbelt Rentals configures as a turnkey rental package, including cabling and distribution panels, designed to deliver approximately 100 kW of prime power for medium-size loads such as stage lighting, catering equipment or site offices. According to the company’s US generator rental catalog, the 100 kW class machines use sound-attenuated enclosures and onboard fuel tanks sized to run for a full work shift at typical loads, reducing the need for frequent refueling on event days or overnight construction. Sunbelt’s generator rental page details these specifications within its towable generator lineup.

From a user’s perspective, the package is designed to arrive ready to plug in and go: operators connect distribution panels to clearly labeled output lugs, start the generator via a simple control panel and monitor load and fuel level from a single interface. Industry coverage of temporary power solutions notes that this type of 100 kW trailer-mounted set typically supports both 120/240 V single-phase and 480 V three-phase outputs, giving event planners flexibility to feed everything from sound systems to chillers without separate units. Reporting on the US equipment rental sector highlights how such mid-range generators fill the gap between smaller 25 to 45 kW units and the 150 to 300 kW sets used on very large festivals or industrial shutdowns.

Noise control is a key selling point for this product class. Sunbelt specifies sound-attenuated, “whisper quiet” enclosures in its marketing for towable generators in the 20 to 200 kW range, reflecting the needs of film productions and residential-area events where local ordinances limit decibel levels. Trade publications covering event production equipment describe how these acoustic housings, combined with variable-speed fans and carefully routed exhaust, allow rental generators to sit closer to stages or camera locations without contaminating audio recordings. For customers, the result is a more compact site layout and less cabling across public areas, which can help with safety and permitting.

As a rental-only product, the AirPac 100 kW’s economics differ from outright ownership of a generator. Customers typically pay a daily or weekly rate that bundles the machine, maintenance and, in many cases, 24/7 emergency support from Sunbelt’s branch network. Analysts of the “equipment-as-a-service” model point out that rental power lets users match capacity to project length and seasonality rather than tying up capital in assets that sit idle between jobs. A recent market report on equipment-as-a-service cites Sunbelt Rentals among the companies benefiting from this shift toward usage-based access to heavy equipment.

Within Ashtead’s broader portfolio, Sunbelt Rentals’ power generation and climate control lines are positioned as growth areas alongside core tool and equipment rental. The company’s latest investor materials emphasize cross-selling between product categories: a contractor renting aerial lifts and earthmoving equipment can add temporary power from Sunbelt to run jobsite trailers, while event organizers often procure lighting towers, fencing and portable HVAC on the same order. Ashtead’s management has repeatedly highlighted the US market’s fragmented nature as an opportunity for national networks like Sunbelt to capture share by offering a one-stop shop, and products such as the AirPac 100 kW generator are part of that integrated service offering.

For consumers and small businesses planning festivals, pop-up retail or seasonal attractions, rental generators at the 100 kW level mark a practical threshold. Below that, equipment often cannot reliably carry multiple food trucks, amplified music and lighting together; above that, logistics and cost start to resemble full-scale industrial projects. Industry commentary on outdoor events suggests that organizers increasingly book power solutions early in their planning, much like tents and staging, which tends to favor large rental chains with nationwide fleets and standardized packages.

Ashtead Group presents Sunbelt Rentals as the primary engine of its North American business, with power generation equipment contributing to the “specialty” mix that has been a key strategic focus. In its latest annual report and investor presentations, the company reports that specialty businesses, including power and HVAC, have grown faster than the general tool rental segment in recent years, supported by infrastructure spending and a strong events market. Ashtead’s investor relations materials describe this specialization as a differentiator against smaller regional competitors.

Sunbelt Rentals’ power fleet, with the AirPac 100 kW class at its core for mid-size jobs, thus plays into Ashtead’s strategy of deepening relationships with professional customers and capturing more project spend per site. Shares of Ashtead Group (ISIN GB0000533728) are listed on the London Stock Exchange in pounds sterling, giving investors public-market exposure to this rental-based model of providing power and equipment.
