WALTER SKTG KSP screw compressors: direct drive mounted on an air receiver
7-year warrantyCompressors with direct drive on a 500 l air receiver
The SKTG KSP range combines direct drive without a belt with a 500-litre air receiver. It has four models: power input of 11 or 15 kW, always either standalone on the air receiver or in the COMBO version with a dryer and filters. Despite the low power input, the machines have large low-speed screw blocks, designed for long and trouble-free operation. The speed is fixed, so the design is simple and suitable for constant air consumption.
Four WALTER SKTG KSP models
Two power inputs, two versions. The designation SKTG 11/500 KSP means a power input of 11 kW and a 500 l air receiver, COMBO adds a dryer and filters. For machines with fixed speed, the air delivery at each pressure is a single value.

What the range offers
Low-speed block with direct drive
Large low-speed screw blocks with 1:1 direct drive are designed for economical and trouble-free operation for many years.
Easy maintenance
Steel oil and air piping and easy access to the coolers simplify maintenance and shorten service inspections.
Control of up to 8 compressors
The control unit can control the operation of up to 8 compressors without a master controller. This comes in handy when the compressor room grows over time.
500 l air tank
The tank is part of the assembly, so the compressor takes up less space than a standalone machine with a separate air receiver.
Fixed speed, or inverter?
Fixed speed is suitable for constant demand. For variable consumption, compare the SFTG KSP range with the same power input and an inverter. If you want the same machine without tank, choose SK KSP.
Ventilek’s advice
Consider the COMBO version when you need dry air.
The dryer and filters are part of the assembly in the COMBO version, so there is no need for separate installation and connection. The difference in weight is 56 kg at 11 kW power input and 58 kg at 15 kW.
Frequently asked questions
- How much air does the machine deliver at higher pressure?
- As pressure increases, air delivery decreases. The SKTG 15/500 KSP model delivers 2.25 m³/min at 8 bar, 2.15 m³/min at 10 bar, and 2 m³/min at 13 bar.
- What does the COMBO version add?
- A dryer and filters in one unit with the air receiver. The complete assembly is heavier than the machine without dryer by 56 kg (11 kW) and 58 kg (15 kW).
- What are the dimensions and connection?
- All models have dimensions of 1,970 × 760 × 1,750 mm and a G ¾″ connection.
- How often is service needed?
- For all WALTER screw compressors, every 2,000 motor hours. Regular maintenance is also a condition for the seven-year warranty.
All models are covered by a 7-year warranty on the entire machine. Warranty and service conditions can be found on the page Šroubové kompresory WALTER. Air delivery is stated according to ISO 1217:2009, Annex C, sound pressure level with a tolerance of ±3 dB(A).
