Radler & Ruf Low-Pressure Blast Machines

(7 Products)
Radler & Ruf low-pressure blast machines for flexible applications and long operating intervals

Radler & Ruf’s current line of low-pressure blast machines covers a wide range of sizes. Available models include 24- and 60-liter versions, as well as a larger series with capacities of 100, 140, or 200 liters. As a result, the product range extends from mobile units for restoration and changing work sites to larger systems with significantly longer refill intervals.

Depending on the application, the working pressure, nozzle, abrasive media, and blast hose can be adjusted for use on delicate or more robust surfaces. The units are also available as complete sets with a blast hose set and blast nozzle and are suitable for historic preservation, facades, wood, metal, renovation, rust removal, and professional surface preparation.

The tank size primarily determines the abrasive supply and operating time. The actual blasting performance, on the other hand, depends largely on the nozzle bore diameter, operating pressure, and the compressor’s available air volume.

Radler & Ruf: How to Choose the Right Low-Pressure Blasting Machines

Radler & Ruf low-pressure blast machines are designed for applications in which the blasting power needs to be finely adjusted to the surface, the abrasive media, and the cleaning task. The decisive factor is not just the tank size, but the interplay of working pressure, nozzle bore diameter, abrasive media, hose size, and available compressed air volume.

Here’s what you should look for when making your selection:

✔ Desired tank size and operating duration
✔ Available compressor power ratings
✔ Desired nozzle bore diameter
✔ Type and grit size of the abrasive media
✔ Sensitivity of the surface to be treated
✔ Desired hose length and mobility

Tank Sizes and Applications

The Radler & Ruf low-pressure blast machines currently available in the store include compact 24- and 60-liter models as well as a larger series with capacities of 100, 140, or 200 liters. Smaller tanks are particularly suitable for mobile applications, repairs, restoration, and changing work locations. Larger tanks reduce refill intervals and are useful when longer blasting times or larger areas are involved.

Compressed Air Requirements and Blast Nozzle

Air demand is primarily determined by nozzle bore diameter and operating pressure. When sizing the system, the compressor’s actual available flow rate should be taken into account. A sufficient air reserve stabilizes the operating pressure and prevents drops in performance during blasting.

Selection criterionMeaning

Working pressureIt is adapted to the surface, the abrasive media, and the desired removal rate.
nozzle bore diameterSignificantly determines air consumption and surface coverage rates.
abrasive mediaMust be suitable for the surface and the desired blasting result.
Typical Applications

✔ Restoration and historic preservation
✔ Wood and facade finishing
✔ Removal of coatings and contaminants
✔ Rust removal and surface preparation
✔ Mobile blasting operations on construction sites and in industrial facilities

FAQ

What is the advantage of a low-pressure blasting machine?
The working pressure can be specifically reduced so that sensitive surfaces can be processed in a more controlled manner.

What is the appropriate tank size?
This depends on the duration of use, mobility, and desired refill frequency. For short, mobile applications, a smaller tank is often sufficient; for longer jobs, a larger volume is more convenient.

Can I use any type of abrasive media?
No. The abrasive media, grit size, metering valve, and nozzle must be technically compatible with each other and with the respective application.

How important is the compressor?
Very important. Without a sufficient supply volume, the desired working pressure at the nozzle cannot be maintained consistently.
