Compressed air shot blasting machines

These machines blast shot by mixing it in compressed air flow. The blasting process is performed manually. The necessary protective gear for the worker is supplied with the machine.

Injector cabin with filter

The injector shot blasting cabin is used for manual blasting of small and medium sized workpieces, which are inserted into the cabin through the side opening. The worker puts his hands in the working area through the oval openings on the front side of the cabin. The openings are equipped with gloves made of wear resistant rubberised material. The blasting process is started and stopped using a foot switch.

Pressure cabin with filter

The pressure shot blasting cabin is used for blasting small and medium sized parts. Its usage is similar to injector cabin. However, the different technology enables higher blasting performance. The only tradeoff is, that the blasting process must be interrupted for a short time when the pressure vessel is empty.

It is appropriate for users who want to blast a wide selection of workpieces with diverse size and shape. The blasting performance is determined by the number of pressure blasting sets connected to the machine and by the performance of the air compressor supplying the machine. The whole machine is designed according to the individual needs of the customer. OTECO already supplied over 45 machines of this type, of which approx. 15 work outside the Czech Republic.

Hand-held shot blasting sets

During the blasting process, the vessel is hermetically sealed from the inside. This enables the necessary air pressure to be built up, which is the used to feed the shot through the feeding valve into the compressed air flow. The pressure vessels have a capacity of 20 to 200 litres.
