A blow-off nozzle is provided and oriented in a direction to discharge a stream of cleaning medium at the blow nozzle causing residual blowing medium to be removed from the blow nozzle.

Provided is a blasting device capable of performing blasting by spraying a slurry of a constant concentration from a blasting nozzle.

The blow-off unit (11) has a blowing nozzle (11a) and a gas supply unit (11c).

A blowing nozzle for connection to a blowing tool to deliver a pressurized, gaseous fluid.

A transverse jet (13) is used to direct an inert entraining fluid (14) over and around the blowing nozzle (5) at an angle to the axis of the blowing nozzle.

The downstream portion of the blast nozzle includes a single conical portion.

The length of the neck of the blast nozzle is sufficient for the arcing contact (3) to remain in contact with the neck (12) while the blast nozzle (5) is moving during opening of the circuit breaker.

Preferably, the ventilation duct (13) is fitted with cooling medium blowing nozzle (16).

A blow device for rear view mirror of a vehicle includes a control circuit (1), an air compressor (2), an air duct (3) and a blow nozzle (4).

At least one blaster (10) is arranged comprising at least one blast nozzle (12), such as a blast lance, in line with the flow direction of the quench gas.

According to the inventive device, the inventive acceleration path is formed between the upper edges and the lower edges of the two blow nozzle openings below the spinning nozzle.

Same is suctioned from the lower end of the slurry suction tube and delivered to the blasting nozzle.

The media blast nozzle has an entrance and an exit and a throat therebetween.

The fluidized ice particulates move via pressure flow towards a blast nozzle (16) to be expelled from the nozzle (16) towards a work object.

The blowing pattern shows the spread of the air in front of the air nozzle and is stated in millimeters [mm] or inches [“].
