BUY NEW & Used Industrial Generators 35 kW GENERATORS FOR SALE

35 kW Generators for Shops, Pumps, Small Equipment, and More

A 35 kW generator sits at the entry point of our commercial lineup, but don’t mistake that for limited capability. It’s a dependable fit for small manufacturing equipment, agricultural pumps and irrigation systems, and backup power for light commercial buildings. Construction crews also lean on it for early-phase site work — lighting, hand tools, and temporary office trailers — before larger equipment comes on-site.

35 kW Generators for Commercial Backup and Emergency Power

A 35 kW generator can be a practical choice for small businesses and facilities that need reliable backup or emergency power without installing a larger generator than their load requires. These units can support essential equipment, lighting, pumps, basic climate control, and other critical loads during an outage. Their relatively compact size also makes them suitable for workshops, small retail locations, agricultural operations, and single-building commercial facilities where dependable power and durable equipment are priorities.

Listing Every Device That Draws Power at 35 kW

Thirty-five kilowatts is a size where a single large starter can set the limit. Write down the loads that will run together, with the starting surge of any motor or compressor beside its running figure, then allow for hot weather or high elevation, which reduce what an engine delivers.

Our power calculator can confirm whether 35 kW covers that list before you buy. Our amperage chart has no 35 kW row, but the rows on either side (3 phase, 80% power factor) list 104 A at 208V and 45.2 A at 480V for 30 kW, and 139 A at 208V and 60 A at 480V for 40 kW. The 35 kW figure sits between those two rows.

Generac SD035 and Kohler 38RCLC: Fuel Burn Near 35 kW

Most 35 kW sets run on diesel or natural gas, and the published ratings for the two fuels are not written the same way.

• Diesel: A diesel set keeps its supply on site, which suits farms, shops, and properties with no gas service. A 35 kW line does not appear on our diesel fuel consumption chart. The two nearest rows are 30 kW, at 1.3, 1.8, 2.4, and 2.9 gal/hr for 1/4, 1/2, 3/4, and full load, and 40 kW, at 1.6, 2.3, 3.2, and 4.0 gal/hr. Generac prints its own standby burn for the SD035: 1.0 gph at 25% load, 1.7 at 50%, 2.4 at 75%, and 3.1 at 100%.
• Natural gas: A gas set runs from a utility line instead of a tank. Kohler’s 38RCLC, the closest Kohler gas model to this size, is rated 38 kW standby on natural gas and uses 205 cfh at 25% load, 327 at 50%, 404 at 75%, and 492 at 100%. Its sheet calls for 5 to 11 inches of water column of gas supply pressure. Kohler lists only a standby rating for this model, defined as power for the length of an outage with no overload capacity. Our diesel chart is not meant for natural gas units.

Diesel sets are filed under industrial diesel generators and gas sets under industrial natural gas generators; each listing names its fuel.

Closest Towable Match to 35 kW: Atlas Copco QAS 45 ID

None of the mobile models on Atlas Copco’s QAS 25-45 ID T4F sheet is rated at exactly 35 kW. The QAS 45 ID is the nearest, and Atlas Copco sells it on its prime figure: 36 kW prime and 40 kW standby, from an Isuzu Tier 4 Final engine.
Its 73-gallon tank carries a printed 30 hours at 75% load, based on 90% of tank volume. Ready to run on its trailer, the unit weighs 2,625 lb, and the trailer package measures 129.5 x 54 x 66 inches. The running gear on the sheet:

• Axle: one torsion axle, rated 3,500 lb with brakes and 3,000 lb without.
• Brakes: hydraulic or electric. A no-brake option is offered on the smaller QAS 25 only.
• Hitch: an adjustable-height pintle with a 3-inch lunette as standard, and 2-inch or 2 5/16-inch balls as factory options.
• Skid option: the skid frame and the trailer mount the same way and can be swapped.

Wheeled units appear under trailer-mounted generators.

What Affects 35 kW Generator Pricing?

Two sets labeled 35 kW can deliver different usable output depending on which rating the number refers to, so start there when comparing quotes.

• Standby versus prime: Generac rates the SD035 at 35 kW standby and 32 kW prime, and its sheet notes that EPA-certified prime ratings are not available in the US. Atlas Copco’s QAS 45 ID works the other way, sold on 36 kW prime with 40 kW standby. Match the rating to the hours you expect to run.
• Warranty tied to the rating: Generac lists a 2-year limited warranty on standby-rated SD035 units and 1 year on prime-rated units.
• Output current: The SD035 sheet prints 121 A at 208V and 53 A at 480V at its 35 kW standby rating, and conductor and breaker sizes follow that current. Compare it with the amperage chart rows quoted above, then total your load with our power calculators.
• Base tank size: SD035 tank options run from 54 gallons, with 17 hours printed, to 300 gallons, with 96 hours printed.
• Condition: Our new generators and used generators sit in separate listings, and on a used set the run hours and service records feed into the number.

• Mounting and housing: a skid or trailer, along with open, weather-protected, or sound-attenuated enclosure options depending on the model.

• Freight: how far the unit travels to reach your site.
