What Is the Professional Line, and Who Is It For?
A professional electric generator isn't just a household generator painted a different color: it has to withstand dust, handle the strain of extension cords, fit in a van, and, sometimes, deliver 400 V. That's what makes it professional.
Seven models with industrial filter Typhonic, which removes dirt before it reaches the engine; a frame with wheels and built-in handles that reduces the volume by 30 %; shots IP67 and cable clips so that a sudden pull won't break the panel. Candanchú and Bentayga dan 230 y 400 V. Y cada modelo existe en S version —30 mA residual current device, manual start—designed for public works and rental fleets. Motor Euro V, copper alternator and regulation SVR which absorbs the tool's initial impact.

What job do you need it for?
Every trade has different requirements: power, dust, 400 V, or simply that it fits in the van. Find the one that's right for you.
Power Tools and Testing in New Construction
Drill, angle grinder, grinder, work lights, installation tests before connection. He goes back and forth in the van every day. Jaca 3,300 W or Panticosa 4,000 W: 30% lower volume, electric start.
Test, Welding, and Drain-Cleaning Pumps
Drain pump, pipe welding equipment, electric drain cleaner, dehumidifiers. Panticosa 4,000 W or Navacerrada 5,500 W due to the pumps’ starting peaks.
Small concrete mixer, hammer, saw
Cement dust around the clock: here's the filter Typhonic It pays for itself. Navacerrada 5.500 W or Astún 7.000 W to start the concrete mixer and jackhammer without any downtime.
Saw, miter saw, and air compressor on the construction site
Installing kitchens, cabinets, and flooring in an area where there is no electricity yet. Sawdust and wood shavings everywhere. Navacerrada 5,500 W with IP67 outlets and cable clips for the extension cords.
Inverter welder and grinder on site
Fencing, structures, and on-site repairs. A 160 A inverter welder requires high peak power: Astún 7,000 W or Bentayga 10 kVA. For continuous welding work, check out the gasoline-powered welder.
Large concrete mixer, pump, or 400-volt compressor
For three-phase machines: Candanchú 8.8 kVA or Bentayga 10 kVA, dual voltage 230/400 V. If you need more than 10 kVA, choose the Big Series.
Shearing machine, milking machine, irrigation pump
Dust, mud, and distance. IP67-rated cameras and a dust filter for working on the farm. Navacerrada 5.500 W or Astún 7.000 W; for three-phase pumps, Candanchú.
Power tool away from the outlet
Hedge trimmers, leaf shredders, pond pumps, and garden lighting on site. Jaca 3,300 W or Panticosa 4,000 W: lightweight and with electric start.
Communities, telecommunications, antennas
Work on rooftops and in spaces without power, using measuring equipment and lightweight tools. Veleta 2,800 W or Jaca 3,300 W: just enough, without carrying extra weight.
When the regulations require it
30 mA residual current device, IP67 outlets, and manual reset without a battery to maintain: the S versions (Jaca-S, Navacerrada-S, Astún-S, Candanchú-S, Bentayga-S) meet the requirements for public works projects.
A fleet that passes through many hands
Equipment that can handle many hours of use and many different users: copper alternator, filter Typhonic, IP67 protection, and manual startup in case the battery runs out between rentals. Those are the S versions. Si tus clientes alquilan "para todo el día", la gama BFT It offers the same models with capacities ranging from 14 to 27 L. The entire fleet lineup is available at Generators for rental companies (S versions).
Stalls and booths without a power connection
Lighting, POS system, beverage cooler, and small equipment for a market stall. Panticosa 4,000 W for a market day; if it’s a long day, better yet BFT; if there are people above, a silent inverter.
Why Choose Profesional
Tubular frame and cold start
A reinforced tubular frame built to withstand the rigors of the job site, and an engine that starts right up—even when cold—at seven in the morning. A power-to-weight ratio designed to make it easy to maneuver around the job site.
Industrial filter Typhonic
A centrifugal prefilter removes heavy debris before it reaches the filter layers. The motor is protected from cement dust, sawdust, or dirt: less maintenance and a longer service life. This is the main difference from a household generator.
30% less volume
Wheels and handles built into the frame. It fits in the van with the rest of the tools and can be moved around the job site without assistance.
IP67 connectors and cable clips
They withstand rain and mud, and prevent a tug on the extension cord from breaking the panel or the outlet—the most common malfunction on a construction site.
Dual voltage 230/400 V
Candanchú It delivers 7 kW (8.8 kVA) at 400 V and 6.5 kW at 230 V; Bentayga, 8 kW (10 kVA) at 400 V and 7 kW at 230 V. Compact three-phase gasoline-powered generator for concrete mixers, pumps, and compressors.
SVR for the tool
Electronic regulation SVR Absorbs the inrush current spikes from hammers, concrete mixers, and compressors without voltage drops. Motor Euro V and copper alternators across the entire product line.
S Version for Regulatory Compliance
30 mA residual current protection, IP67-rated outlets, and manual reset (no battery that discharges between jobs). What public works projects require and rental companies prefer.
Built to Last
A professional generator pays for itself based on how many hours it lasts, not on how much it costs on the first day. Here are the features of the Profesional model that extend its lifespan.
100% Copper Alternator
Copper heats up less and withstands continuous operation better than aluminum. It is the component that determines how many years a generator will last.
The engine runs cleanly
The filter Typhonic It removes heavy dirt before it reaches the engine. Less internal wear caused by cement dust, sawdust, or dirt, and more kilometers between maintenance visits.
SVR that protects
The electronic regulator smooths out the tool's startup spikes: the voltage doesn't drop or spike suddenly, so neither the generator nor your machines are affected.
Common breakdowns—prevented
IP67-rated connectors that are rain- and mud-resistant, and cable clips to prevent an extension cord from tearing the panel. These are the two most common causes of damage on construction sites.
No battery to maintain (S version)
Manual starting on the S models eliminates the problem of a dead battery between jobs or rentals: fewer service calls, fewer downtime.
Spare Parts and Technical Support in Spain
Filters, spark plugs, alternators, and genuine parts from Genergy. Un generador que se repara vuelve a la obra; uno sin recambios va al cajón.
Standard or S version? Which of the seven?
The standard version features an electric starter and is the most convenient option for self-employed professionals. The S version adds a 30 mA ground fault circuit interrupter, IP67-rated outlets, and a manual starter: this is the model requested by public works projects and rental companies. The fourteen items in the product lineup consist of these seven models in their two versions.

Tank capacity and power data from the official catalog Genergy 2026. Tanks ranging from 2.6 to 6 L (3–4 hours at 25% load): this lineup is designed for transport and work. If you need to go all day without refueling, the same models are available in version BFT 14–27 L.
How to Use It Safely on a Construction Site
Five rules that prevent 90% of the problems with a gasoline-powered generator on the job site.
Always outdoors
Gasoline engines produce carbon monoxide, which is colorless and odorless. Never operate them inside a shed, basement, or enclosed structure; if you must keep them indoors, extend the exhaust pipe outside and ensure proper ventilation.
Ventilation and Heat
A 5,000-watt generator gives off as much heat as a 5,000-watt heater. Make sure there's plenty of space around it: enclosing it to keep the noise down will cause it to overheat.
Protected from direct rain
IP67-rated connectors are splash- and mud-resistant, but the electrical panel must not be exposed to direct rain. A roof that is open on the sides is sufficient.
Differential and extension cords
For public works, use a 30 mA residual current device (S version). Use extension cords that are short and have the appropriate gauge: every extra meter results in voltage loss and heat buildup in the cable. Hang them on the cable hooks.
Fueling and Oil
Refuel when the engine is off and cold, using an approved container. Check the oil daily and change it every 50–100 hours: this is the best way to extend the engine’s life. See generator accessories.
Tool Start-up
Start the generator first, then the tool, one at a time; motors (concrete mixer, air compressor) draw 2–3 times their rated power when starting up. The adjustment SVR It absorbs that peak if the generator is properly sized.
