The most powerful machine in the range that fits under a low ceiling — the enclosure is 1,690 mm tall. 21,000 l/min at ten bar, regulation from 6,300.

The smallest pressure penalty in the whole range: eight bar costs only 500 l/min against seven. 24,000 l/min, DN 80 outlet, weight 2,900 kg.

The backbone of a large compressor room — 28,000 l/min at eight bar holds the base demand while smaller machines come in at the peaks. The controller sequences up to sixteen.

The highest delivery the range will give at normal industrial pressure: 31,000 l/min. Same frame as the 132 kW, only 100 kg heavier.

The lowest enclosure of the large machines — 1,690 mm, 460 mm less than the 132 kW. Into a low compressor room it often fits as the only one. 24,500 l/min.

The first machine in the range to pass thirty cubic metres a minute: 30,000 l/min. It weighs 3,050 kg, stands 2,150 mm tall and needs 25,000 m³/h of ventilation.

The top of the EPM2 range — 33,500 l/min, over thirty-three cubic metres of air a minute from a single enclosure. It needs 30,000 m³/h, twice what the 55 kW asks.

The most expensive pressure tax in the range: ten bar costs 23 % of the air here. It gives 23,000 l/min, but at seven bar that would be 7,000 l/min more.

The most powerful machine in the range without a receiver — 696 l/min, twice the 3 kW. Still 180 kg and a 650 × 600 × 860 mm enclosure.

The most powerful machine in the range at ten bar — 27,000 l/min. It never drops below 7,600 l/min, so it wants steady demand or a substantial receiver.

Compressor, dryer and 200 l receiver on one frame in 0.82 m². The entry 3-in-1 package delivering 320 l/min, with no assembly certification needed.

The smallest machine in the range at the highest pressure. 2,300 l/min at ten bar, an enclosure of 1,200 × 800 mm and 66 dB(A) — for a workshop where people work alongside it.

The way into the EPM range. Fifteen kilowatts gives 3,000 l/min at seven bar, and the inverter takes it down to 750 — a quarter of its output.

The 15 kW at eight bar, 2,900 l/min. The extra bar costs only 100 l/min here, the smallest difference anywhere in the range.

Ten bar from the 18.5 kW: 2,900 l/min, exactly what the 15 kW gives at eight. Same enclosure, same 66 dB(A).

The 18.5 kW in the same enclosure as the 15 kW, but 700 l/min stronger: 3,700 l/min at seven bar, still only 480 kg.

Eight bar and 3,500 l/min in a 1,200 × 800 mm enclosure. Regulation from 1,100 l/min, so the machine serves the workshop even on a single air tool.

Ten bar and 3,500 l/min, the last machine in the range with an R 1" outlet. Above it the pipework is sized for R 1½".

The most powerful machine in the range’s small enclosure. 4,100 l/min at seven bar, 560 kg — 80 more than the 18.5 kW, but not a centimetre more.

The 22 kW at eight bar gives 4,000 l/min. The usual choice where compressed air drives several machines at once.

The 30 kW at ten bar gives 5,200 l/min and regulates from 1,300 — down to a quarter of its output, the lowest of any ten-bar machine in the range.

Here the range’s second enclosure begins — 1,300 × 1,000 × 1,370 mm and an R 1½" outlet. The 30 kW gives 6,200 l/min at seven bar, half again what the 22 kW gives.

Eight bar from the 30 kW: 6,100 l/min, only 100 less than at seven. Weight 830 kg, noise level 68 dB(A).

Ten bar from the 37 kW: 6,500 l/min. The regulation floor here is 2,300 l/min, higher than on the seven-bar version — it wants steadier demand.

The 37 kW shares its enclosure with the 45 kW but runs 2 dB(A) quieter. 7,400 l/min at seven bar, 850 kg.

Eight bar and 7,350 l/min — only 50 l/min less than at seven, the smallest pressure penalty in the upper half of the range.

The most powerful machine in the range at ten bar, 8,000 l/min. It will not drop below 3,000 l/min, so it belongs where air is drawn continuously.

The top of the EPM range. Nine and a half thousand litres a minute at seven bar, regulation from 2,500 and ventilation of 9,000 m³/h.

The highest delivery in the range at normal industrial pressure: 9,400 l/min. Enclosure 1,530 × 1,100 mm, weight 890 kg, 72 dB(A).

The lowest power in the range at the highest pressure. 10,500 l/min at ten bar with regulation down to 2,600 — it copes with a weak night-time demand.

The entry machine of the range, set to seven bar. Up to 12,500 l/min with regulation from 3,500 — the first compressor that asks for a room of its own.

The 55 kW at eight bar, the most common combination in its class. 11,500 l/min at the pressure most industrial pipework is sized for.

At ten bar it gives 12,000 l/min, almost what the 55 kW gives at seven. A pressure loss of only 14 %, the least of any ten-bar machine in the range.
