Product detailed description
A floor-mounted rotary screw compressorfor workshops that already have a receiver and only need to replace the air source. It takes up690 × 480 mmof floor space and weighs 99 kg.
It isthe stronger of the two CROSS versions— it delivers 848 litres per minute, seventy percent more than the four-kilowatt version. It suits shops running several air tools at once, or sandblasting and painting all day.
First service after 2,000 hours
What to know before you buy
Continuous duty
Unlike a piston compressor it needs no cool-down breaks — it runs a whole shift.
400 V supply
A three-phase connection is required. Soft start loads your fuses far less than a piston machine.
Service after 2,000 h
The first service is due after two thousand operating hours or one year.
Smooth running
Two rotors compress the air continuously — none of the pulsation a piston machine sends into your piping.
What it looks like in service
The stronger unit without a vessel, for shops that already have both receiver and piping in place.
At 63 dB(A) the machine stands in the workshop itself — no separate compressor room and no long pipe run, usually the most expensive part of the installation in a small shop.
Who this particular model is for
Plasma cutting with continuous demand.
Several workstations on one line.
Sanders and extraction all day long.
Which CROSS to choose
The usual question is not whether to buy a screw compressor, but which one from the range. Here is this model next to its closest neighbours.

Frequently asked questions about this model
- When should I take 7.5 kW instead of 4 kW?
- When several tools run at once, or one with continuous demand — sandblasting, plasma, long spray jobs. It delivers 848 l/min, seventy percent more.
- What size receiver does it need?
- At this output plan for two hundred litres or more. A smaller vessel would lead to frequent cycling.
- Can it handle sandblasting?
- Yes, as long as the blast gun stays within the 848 l/min on offer. Check the consumption of your particular nozzle — it is usually higher than expected.
Air delivery measured per ISO 1217 ed. 4 (2009), annex E, at a reference pressure of 9.5 bar; noise per ISO 2151 (2004).
Without a receiver this unit makes sense where the tank is already standing in the workshop. Otherwise the CRS-7,5/10-200 set is simpler, with the compressor and the 200-litre tank in one frame. The weaker CRS-4/10 gives 498 l/min and is three decibels quieter. Up to 15 kW the machines then continue in the ABAC SPINN Maxi series.
When the receiver is in place and only the compressor has worn out, this is exactly the part you swap. Otherwise it is simpler to take the whole set.
