Description

The FIRMAN P05706 generator features 7100 starting Watts and 5700 running watts. Power is supplied by our Max Pro Series 389cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the P05706 running at 72 decibels, and our spark arrester has been approved by the USDA Forest Service. The industry-leading 8-gallon fuel capacity provides a whopping 13 hours of run time. Our rubberized Thresher handle makes recoil starting a snap – even with bulky gloves.

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Firman P05706 in use

The Firman P05706

The Firman P05706's core is the 389 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 5700W and a peak wattage of 7125W.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a shower). Its starting mechanism is based on a simple traditional pull-start mechanism.

With a fuel capacity of 8 gallons, the P05706 may run for around 13 hours at 50% load with a full tank (fuel consumption around 0.62 GPH).

The quite high THD (<25%) of the P05706 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

This Firman generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the P05706 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The Firman P05706 has a conventional, open frame design, of the following dimensions: L28.4 x W27.5 x H26.8 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 178 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). 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 P05706

The P05706's control panel

The P05706's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P05706's package also includes these accessories: oil, funnel and tool kit.

Emissions

The Firman P05706 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, which makes it suitable for use in forested areas.

The Firman P05706 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P05706 compare to generators of similar power (between 5500 and 6500 W).

  • With a dry weight of 178 pounds, the Firman P05706 finds itself in the expected weight range for generators able to produce between 5500 and 6500 rated watts. If weight is your top priority, one of the champions in this power category is the Pulsar G65BN, weighing just 126 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 74 dBA. For those who are looking for a less noisy device, we suggest the Honda EU7000iS. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Since the P05706 boasts with a run time of around 13 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Cat RP5500, as it provides around 15 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. As this generator uses an estimated 0.62 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.

The bottom line

STRENGTHS:
  • Several accessories included
  • High run time
AVERAGE SPECS:
  • Decent weight (178 lbs)
  • Acceptable noise (74 dBA)
  • Decent fuel efficiency
