Pressure Blast Cabinets from Radler & Ruf

Radler & Ruf pressure blast cabinets are designed for professional applications that require higher blasting performance than that provided by traditional suction blast cabinets. The pressure blasting process feeds the abrasive media from a pressurized blast pot to the nozzle. This provides high abrasive media flow and removal rates, which are particularly beneficial for intensive cleaning, rust removal, paint stripping, and the processing of durable surfaces.

Models 4050 and 4055

This category features the 4050 and 4055 pressure blast cabinets. Both models are equipped with a Cyclone 900 abrasive cleaning system and an AE-T 0.14 filtration unit with manual filter cleaning. The main difference between the models lies in the cabinet dimensions and, consequently, the available working space. This allows you to select the system that best suits the workpiece size, available space, and task at hand.

Sizing a Workspace for Practical Use

When selecting the size, you should not only check whether the workpiece fits inside the cabinet. For efficient operation, there must be sufficient space to rotate and reposition components and to reach the surface from an optimal blasting angle. A workspace that is too small can significantly complicate the process and limit productivity.

Closed-loop abrasive cleaning

In professional blasting operations, it is not only the actual blasting performance that matters. A properly functioning abrasive reconditioning system is just as important. The cyclones separate dust, abrasion residue, and unsuitable components from the reusable abrasive media. This helps maintain more consistent process conditions and allows for more economical use of the abrasive media.

Filtration unit and visibility in the work area

The integrated filtration unit captures the dust generated during blasting and ensures good visibility inside the cabin. Manual filter cleaning allows for regular cleaning of the filter element and helps maintain extraction performance during operation. In environments with high dust levels, filter cleaning should be performed more frequently.

Why Choose a Pressure Blast Cabinet?

Unlike the injector principle used in a suction blast cabinet, pressure blasting involves feeding a larger quantity of abrasive directly into the compressed air stream. This enables high material removal rates and often reduces processing time for demanding tasks. At the same time, compressed air consumption and wear are higher, which is why the system should be technically designed to meet these requirements.

The nozzle and compressor determine the performance

The available blasting capacity is largely determined by nozzle size and compressed air flow rate. As the nozzle bore increases, the air demand rises sharply. The compressor must be able to maintain the desired operating pressure under full blasting load. Adequately sized piping and low pressure losses in the compressed-air treatment are also important.

Choose the right abrasive media for the job

The hardness, grain shape, and grit size of the abrasive media influence the material removal rate and the resulting surface finish. For sensitive materials or specific surface requirements, the pressure and abrasive media should be carefully matched. A test area helps prevent unnecessary material removal.

For industrial and trade applications

Radler & Ruf pressure blast cabinets are suitable for businesses that process workpieces regularly and with high blasting capacity. Before making a selection, workpiece dimensions, the desired surface finish, the abrasive media used, daily operating time, and available compressed air should all be considered together. We provide support in selecting the appropriate cabinet size and in coordinating the overall system.
