SKL 700 and SKL 1100 – oil-free screw compressors
For silo vehicles: standard, LS and with front-mounted gearbox
The oil-free SKL 700 and SKL 1100 screw compressors are built for silo trailers and stationary unloading systems. They deliver 385 to 1,050 m³/h at a constant 2.5 bar (g).
Three versions suit every power take-off: the standard version, the LS version for lower drive speeds and the version with a 1:2 or 1:2.5 front-mounted gearbox.
Flow rate
385 to 1,050 m³/h
Operating pressure
2.5 bar (g)
Power requirement
22.5 to 52.5 kW
Versions
Standard, LS, gearbox
Why the SKL 700 and SKL 1100?
The rotor profile is designed for high efficiency, low noise and low discharge temperatures. This way the compressor is gentle even on sensitive bulk goods.
The wide speed range can be adapted to a great variety of power take-offs and chassis.
- Oil-free screw compressor for silo vehicles and stationary unloading systems
- Flow rate range 385 – 1,050 m³/h
- Operating pressure up to 2.5 bar (g) across the entire speed range
- LS version with reduced drive speed
- Wide speed range for flexible adaptation
- Integrated oil pump and easily replaceable oil filter
- Low weight, compact design
- Front-mounted gearbox with 1:2 or 1:2.5 ratio, clockwise or anticlockwise rotation
- Front-mounted gearbox: drive shaft at the top or side (left/right); direct drive only, no V-belt
Application
Silo vehicles

Frequently asked questions
Why oil-free?
With food, plastic granules or chemicals, no oil may get into the goods being transported. Oil-free compressors rule out this risk.
Standard, LS or front-mounted gearbox?
That depends on the speed of your power take-off. The standard version runs at 2,000 to 3,600 rpm, the LS at 1,630 to 2,930 rpm, and with a front-mounted gearbox just 652 rpm is enough. We select the right version with you.
How is the compressor driven?
Depending on the vehicle, via power take-off and cardan shaft, V-belt or hydraulic motor. We work out with you and the body builder which drive is right.
Who supplies, installs and maintains it?
We do. As CVS representative, we supply compressors and vacuum pumps, advise on installation in the vehicle and take care of maintenance and repairs.
