EL-CCJYSB equipment with flexible suction arm can 360 degree hovering with suction air volume control valve. Its good tensile properties can not only hover with various types of welding fumes and dust purifier supporting the use, can also be installed directly on the wall or on a system with piping for dust emissions. All stainless steel cover mouth and wall bracket, never rust. Resistance to corrosion, acid salt, high temperature, light weight, high strength, with power unit and effortless operation, hover freely. Suction arm is widely used in metal processing, welding fumes, the workpiece grinding, thermal processing mist treatment, odor removal, dust removal and other industries. EL-CCJYC skeleton external suction arm suction arm is widely used in metal processing, welding fumes, the workpiece grinding, thermal processing mist treatment, odor removal, dust removal and other industries. Compared with fixed piping systems, flexible suction arm with unparalleled performance advantages that can adapt to all kinds can not install the suction line of complex conditions, can be arbitrarily placed on the complement of the best position to effectively complement set of welding fumes, the connection joints and rotary connections suction hood fixed base makes the dust, exhaust fumes away from the worker's breathing zone. EL-CCJBZ wall-mounted vertical suction arm Flexible arm outer arm tube for the import of high-quality PVC and fiberglass composite rebar wire tube, high temperature, corrosion resistance, light weight arm thin, elastic medium characteristics. Stainless steel tube support bracket for a group of self-balanced linkage, with a full range of features hover, pulling the handle on the cover mouth, the mouth can be easily stretched to its hood arm length can reach anywhere and hover in the ideal position state soot absorption, without any auxiliary support facilities. Hover its good tensile properties can be mounted directly on a wall or on a system with piping for dust emissions. EL-CCJC extended suction arm extending Ilan EL-CCJC extended suction arm extending from the rotary bearings are mounted on the wall extension arm bracket used in conjunction with conventional suction through the wall bracket with the shaft mount installation, the intermediate with a connector, flexible and able to turn round, to achieve greater operating range. Wind capacity in the required scope of work is relatively large, medium temperature higher than normal temperature case, there are a lot Ilan designed for gas, vapors or non explosive dust environment design. Typical application areas include metal manufacturing or other requirements of the amount of wind pumping industry, can also be used to produce large amounts of spatter welding, laser or hand plasma cutting, metal spraying, sanding or other requirements of the movable arm balance, excellent performance, ease of positioning The process. Ilan extension arm can be lengthened or central purification system and fan suction pipe connections. According to the situation in the longer extension arm to install additional equipment, coil device, suction tube, suction hood vent.
