Description

Zoom on the Firman T08072

In a nutshell, the Firman T08072 is a portable generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals in need of safely powering high-intensity work or lighting equipment
  • RV travellers wishing to enhance their freedom and nomad lifestyle

In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

Power & Run Time

The Firman T08072 in use

The Firman T08072

The Firman T08072 delivers 120/240V and benefits from a tri-fuel technology that allows it to run on gasoline, propane, or natural gas. When gasoline-powered, it enjoys a running wattage of 8,000W and a peak wattage of 10,000W. When propane-powered, it benefits from 7,250 rated watts and 9,050 peak watts. Its natural gas operation offers 5,500W of rated wattage and 6,900W of starting wattage.

The generator features a manual recoil starter system and also an easy-to-use and reliable electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher).

With a fuel capacity of 8 gallons, the T08072 can operate for around 12 hours at 50% load using gasoline (fuel consumption around 0.67 GPH), or for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) using propane.

Considering its relatively high Total Harmonic Distortion (THD) of less than 14%, it is not recommended to rely on the T08072 for powering sensitive electronic devices.

Outlets

The control panel is equipped with the following 5 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

If you own an RV with a 50-amp service, you can consider this Firman unit as RV-ready, as it features a 14-50R outlet. Its L5-30R receptacle can also be used for a simple RV connection with an L5-30P to TT-30R adaptor. In addition, equipped with a twist-lock L14-30R receptacle, the T08072 is engineered to be transfer switch ready, enabling simple hookup to your breaker box to provide backup power for your home during blackouts.

Portability

Measuring L29.8 x W27.5 x H26.1 in, the Firman T08072 showcases a classic open frame layout, offering stability and simple maintenance access to components, while facilitating air circulation. The device has been designed for tough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 213 lbs make may make it challenging to manually lift and transport. Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Firman T08072

The T08072's control panel

The control panel of the T08072 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator allows you to instantly see if the generator is ready.

Benefiting from its built-in fuel gauge, the generator allows for easy and immediate gas level inspections.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

The T08072 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman T08072 also comes with several accessories, including: natural gas hose with NPT adapter, tool kit, funnel, oil and propane hose.

The Firman T08072 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman T08072 compare to multi-fuel generators of similar power (between 7500 and 8500 W).

  • At 213 lbs dry, the Firman T08072 is consistent with the standard weight profile for multi-fuel devices ranging from 7500 to 8500 rated watts. If you are mindful of weight, the Genmax GM10500XiT is among the top contenders in this power range, with a dry weight of 123.5 pounds.
  • As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. If you wish to prioritize minimal noise, the DuroMax XP9500iH stands out as one of the quietest options among generators of similar power, with a rating of 61 dBA.
  • The T08072 provides a higher run time than similarly powerful multi-fuel devices, reaching around 12 hours at 50% load. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 100416, which is able to run for around 12.5 hours.
  • While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. This generator is one of the more fuel-efficient options in its power range, consuming approximately 0.67 GPH (gallon per hour) at 50% load. To prioritize fuel savings, we advise considering the Powerhorse s10500id, which stands out for its gasoline efficiency, consuming just 0.59 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 7500-8500W multi-fuel generators, the Firman T08072 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
