Champion FM Series
Built to Deliver ValueChampion has been building screw compressors for more than 55 years. The FM Series from 2.2 to 132 kW is made for small and medium-sized companies: easy to install, simple to maintain and designed for continuous operation.
55+years of screw compressor experience
30quality checks before each compressor is tested
5 yearsfree extended warranty
≥ 25%less energy with FM RS regulated speed
To ISO 1217 (flow) and IEC 60204 (electrical equipment). The data is stored and a test report is available for every compressor.
Performance and critical components of every compressor are recorded in a database.
Rotors ground on CNC machines with online laser measurement. FM15–FM22 use the Enduro airend with integrated separator and oil filter.
ISO 9001, ISO 14001 and ISO 45001, Lonate Pozzolo plant (Italy).
Up to 10% more flow than the FM22: 3.36–3.79 m³/min at 22 kW, fixed or regulated speed, stand-alone or on a 500-litre receiver.
A 7.5 or 11 kW compressor on a 270-litre receiver with CHR refrigeration dryer, CHF filters, condensate drain and oil/water separator. 10 bar, 0.97–1.39 m³/min.
Speed follows air demand; the drive exceeds class IES2 to EN 61800-9. Savings of at least 25% of energy costs.

Technology
Two rotors – male and female – turn inside the airend. Air is trapped between the profiles and the casing, the chamber volume shrinks as they rotate and pressure rises. Compression is continuous, so the flow is even and pulsation-free.
Air enters through the intake filter and inlet valve into the chambers between the rotors.
As the rotors turn the chambers shorten and pressure rises evenly. Oil seals, lubricates and carries away heat.
The separator removes the oil from the air and returns it to the circuit. Residual oil is below 3 ppm (L30–L37).
The aftercooler cools the air, condensate is drained, then drying and filtration to the required ISO 8573-1 class.
One motor, four rotors, one semi-integrated casting. The patented FourCore airend from the Centre of Excellence in Simmern (Germany) delivers two-stage efficiency in the size of a single-stage compressor – on L110FC–L290FC it is 8–10% more efficient than a conventional single-stage unit.
CompAir designs and builds its rotors itself, on CNC rotor grinding machines with online laser measurement.
IE3 as standard, IE4 optional (L30–L37) and on L75 e-models and fixed-speed L45–L55, PM IE5 on L45–L55 RS.
Factory-fill lubricant for up to 4,000 hours, automatic belt tensioning (L07–L22) and automatic motor lubrication (L75, FourCore).
Full performance up to 45–46 °C ambient (L07–L22). RS cabinet protected by replaceable inlet filters.
Energy
Compressed air accounts for about 10% (in extreme cases up to 40%) of energy costs in an industrial company, and energy for up to 80% of a compressor's lifecycle cost. This is where the savings are.

14,080 €electricity cost for 88,000 kWh per year
up to 4,930 €savings with regulated speed (RS) when demand varies
61,600–82,700 kWhof heat you can return to heating or process – worth 5,540 €–7,440 €
Simplified: rated power × hours. Actual consumption depends on load. RS savings of up to 35% and 70–94% recoverable heat are figures from CompAir brochures (Champion states at least 25% RS savings). We make an exact calculation based on a measurement.
About 70% of the electrical energy turns into heat during compression. Without recovery you pay for it twice: once in electricity, then again for the fans or cooling water that remove it. Integrated or retrofit heat recovery saves up to 75% energy.

| CA2 | 30–37 kW | 23–30 kW |

Technology comparison
It depends on air demand, operating pattern and how stable the pressure must be.
Most common in small workshops where the compressor does not run all day.
The standard choice for industry and any system with larger or constant air demand.
