Suction Blaster is the simplest and most effective way to remove corrosion and old paint. Suction Blaster is a clean, dust free sand blaster that leaves the surface cleaned and well prepared for painting, filling etc. When the cabinet and power module are correctly set-up, the cabinet is ready for operation by actuation of the foot pedal. Fully depressing the foot pedal causes air to flow through the blast gun. Air moving through the gun draws media into the blast gun mixing chamber. The media mixes with the air and is propelled out the nozzle. After striking the object being blasted, the blast media, along with fines, dust, and byproducts generated by blasting, fall through the grate into the cabinet hopper. These particles are drawn into the reclaimer for separation. Dust and fines are first separated from the reusable blast media. Next the media is screened of oversize particles, and returned to the reclaimer hopper for reuse. Dust and fines are drawn from the reclaimer into the dust collector which traps the dust, discharging clean air. When the foot pedal is released the blasting stops.

Operating Principles The Semi down draft type paint spray booth is suitable for any type of Air-less and Electrostatic painting. The system consists of painting booth enclosure, air intake filter, Filter channels for paint trap, air exhaust system, complete with electric motor, outlet duct, canopy etc. The fresh air enters into the system from the top of the booth passing through 2 stage filters. This allows air to flow vertically downward thereby washing the operator and the job for better visibility to the operator. Simultaneously the exhaust air system sucks the suspended paint particles and fumes from the booth. These suspended paint particles gets trapped in the filter channels which are provided on the bottom side of the wall.

Blast Room – The job is placed inside the blast room and the blasting operation is carried out by operator manually. Used abrasive falls down into the screw conveyor unit from where it is conveyed by longitudinal screw conveyors to cross screw conveyor.

surfex robotic shot peening machines with following features:the shot peening process is based on the effect of introducing compressive stresses in the surface of a metal part by controlled impinging with spherical particles. By this the resistance against fatigue will be increased and therefore also the life of a part.in the space and aircraft-industries the advantages of the shot peening process are already known: the increase of the fatigue-life of critical parts without weight increase. The designers who used shot peening in applications where the effects of fatigue were caused by grinding, electrical discharge- and electrochemical-machining (edm and ecm), electroplating, anodising, thermal spraying and welding. It also can help increase resistance to fretting, galling, caviation erosion, stress-corrosion cracking, intergranulair corrosion and hydrogen-embrittlement.   we are specializes in the general blast technologies for cleaning, roughening and activating surfaces. This way we were able to encounter demands of the industry in the for the shot peening process. to control the shoot peening process, one needs the very precision of the shot peening parameters. Surfex started with the development of precise controlled parameters: • shotsize• shot material and shot shape• shot velocity and shot flowrate• aiming of the nozzles (distance and angle)• shot peening time these parameters determine the intensity (indication for compressive stress) and the coverage (indication for effectively impinging the complete surface). surfex shows its capability to precisely control, monitor and record the critical shot peening parameters.
