Low-pressure blasting
What is low-pressure blasting?
In low-pressure blasting, the abrasive hits the surface with much less pressure than in conventional pressure blasting. On the PREMIUM fine-blasting machines, the blasting pressure can be infinitely adjusted from 0.1 bar. This lets you remove dirt, deposits and old paint without damaging the substrate.
The principle is that of a pressure blasting machine: the vessel stays pressurised at all times, and the hardened fine metering valve feeds the abrasive into the air flow in measured amounts. You set the pressure on the gauge before blasting. With the VARIO nozzle you work dry, with water mist or wet.
Models
25 or 60 litres?
Both machines work on the same principle. They differ mainly in size, weight and maximum pressure.
PREMIUM 25 L
Compact and mobile: for on-site work and confined spaces. A smaller compressor is sufficient.

Heritage and restoration
Clean natural stone, metal and wood step by step while preserving the patina. Surfaces can also be matted, polished and deburred.
Fire damage restoration
Gently remove smoke condensate. This calls for a delicate touch.
Graffiti removal
Remove graffiti from a wide range of materials and surfaces.
Façade cleaning
Clean natural stone, brick, render, concrete and wooden surfaces.
Paint removal
Strip emulsion paints from masonry and render.
Ceramics and tiles
Remove deposits from glazed and unglazed ceramics.

VARIO nozzle technology
Three blasting techniques with one nozzle
With the VARIO nozzle you choose the right blasting technique for every task: dry, with mist or wet. For the swirl-jet method, nozzles are available in 4, 6, 8.5 or 10 mm.
The VARIO nozzle is an optional accessory. More about VARIO technology →
QUICK STOP™
Safety shut-off directly on the vessel
Release the hand lever and the blast stops instantly. The SAPI quick-stop safety shut-off is mounted compactly directly on the blast vessel and meets the regulations of the German employers' liability insurance associations.
- Full pressure instantlyThe vessel stays pressurised. When you restart, full blasting pressure is available at the nozzle immediately.
- Less abrasiveNo unnecessary abrasive run-on, less wear on the blast hose.
- No condensate in the vesselThe vessel is not vented and repressurised with every start and stop.
- One-person operationThe blasting pressure is shown on the gauge and can be changed without starting first.
- Less compressed airLower compressed air requirement and therefore lower fuel consumption with a diesel compressor.
- Easy to maintainNo control valves or diaphragms. Only the blast hose in the shut-off needs checking.

FAQ
Questions about the low-pressure blasting machines
What blasting pressure do the machines have?
The PREMIUM 25 L is infinitely adjustable from 0.1 to 8 bar, the PREMIUM 60 L from 0.1 to 12 bar.
Which compressor do I need?
Allow for a delivery rate from approx. 1,500 l/min. The exact requirement depends on nozzle and pressure. The compressor calculator shows you how to size it.
Can I also blast wet?
Yes. With the VARIO nozzle you work dry, with water mist or wet. The nozzle has a water supply with regulating valve.
What is included in the scope of delivery?
The blasting machine with permanently mounted QUICK STOP™ safety shut-off, pressure regulator and water separator. Blast hose package, VARIO nozzle and protective equipment are available as accessories.
25 or 60 litres: which machine is right?
The 25 L is compact, lighter and intended for on-site work or confined spaces. The 60 L holds more abrasive, so you refill less often, and it reaches up to 12 bar.
Which abrasives can I use?
The abrasive metering valve is suitable for all common abrasives. For very fine-grained abrasives, the vibrator set ensures an even flow.
