Screw compressor WALTER SK 37 KSP input power 37 kW, air delivery 6.2 m³/min at 8 bar, direct drive, fixed speed, 7-year warranty
Code: SK-37-KSP
Product detailed description
WALTER SK 37 KSP screw compressor, the middle one of three models in a shared enclosure
The SK 37 KSP sits in the middle of the trio, which also includes the SK 30 KSP and SK 45 KSP. At 8 bar it delivers 6.2 m³/min, at 10 bar 5.6 and at 13 bar 4.5 m³/min.
Compared to the SK 30 KSP, it has 7 kW more input power and weighs 73 kg more; compared to the SK 45 KSP, it has 8 kW less and is 99 kg lighter. The 1,500 × 1,030 × 1,280 mm enclosure, the G 1½″ connection, and the 66 dB(A) noise level are the same for all three.
Configuration of this machine
- Screw element coupled directly to the motor · fixed speed without inverter · three-stage oil separation
- Air delivery 6.2 m³/min at 8 bar, 5.6 at 10 bar and 4.5 at 13 bar
- Enclosure shared with the SK 30 KSP and SK 45 KSP, weight 591 kg
- Connection G 1½″, noise level 66 dB(A)
- Power supply 400 V / 3 / 50 Hz, WALTER CONTROLLER control unit
Who it suits
For operations with steady consumption that have outgrown the SK 30 KSP but do not yet need the strongest model in its enclosure class. It works well as a middle choice if consumption is only expected to increase moderately.
When to choose a different model
Lower consumption
Lower consumption is covered by the SK 30 KSP: in the same enclosure it delivers 5.21 m³/min at 8 bar and weighs 518 kg.
Higher consumption
A step up is the SK 45 KSP, with an air delivery of 7.51 m³/min at 8 bar and a weight of 690 kg.
What the parameters imply — calculated values
The values are calculated from the maximum air delivery at 8 bar and serve for comparing models with each other, not as a guaranteed value.
Frequently asked questions
- How does the SK 37 KSP differ from a two-stage machine of the same power input?
- The two-stage variant with an inverter is offered by SF 37 DSP. At 8 bar it delivers up to 7.5 m³/min, i.e. 21% more, but it weighs 841 kg and is housed in a larger cabinet measuring 1,610 × 1,043 × 1,380 mm.
- How is the drive power transmitted?
- The screw block is connected directly to the motor via a coupling, so torque is transmitted without losses. The gears in the screw blocks are manufactured according to the AGMA standard.
The machine is covered by a 7-year warranty on the entire machine. Warranty conditions, maintenance, and a comparison of all 17 models can be found in the category WALTER SK KSP screw compressors: direct drive without losses.
Ventilek advises
All three models fit on the same footprint, but they do not load the floor equally: the heaviest is 172 kg heavier than the lightest.
