Fume extractor8/2/2023 Separate and strip the fan cord’s conductors Strip all three of the power cord conductorsĬut the fan connector off the power cord that came with the fan with a little more than enough wire to reach the switch This stain relief will protect your connections should the cord get pulled or yanked. Tie a knot in the power cord to prevent it from being pulled out the power cord hole and grommet. Strip the outer insulation off of a sufficient length of the power cord to expose the insulated conductor wires Pass the cord through the wire grommet from the outside of the enclosure and pull through a good length of cord 25" wire grommet into the power wire hole on the enclosureĬut the C13 (computer plug) off of the IEC power cord Mount the fan and the chrome grill on the back lid leaving the nylon lock nut intend for the ground connection loose Depending on how your enclosure fits together, at this point you might want to make some notes on the back of the lids and inside of the enclosure denoting top, bottom, front lid, back lid, etc.ĭetermine which fan mounting bolt is going to hold the ground wire and remove the paint from the fan in that area If everything fits and works up to this point, disassemble everything and get ready for paint. Rather than struggle with the switch, I ran the power cord that came with the fan out the switch hole so I could power the thing up. I made sure the switch fit when I filed the hole. If your switch hole is just big enough, it can be difficult to pop the switch in and out. Mount the filter sandwich and the fan in the enclosure with the lid screws included with the enclosure. Secure the Silverstone grill with 4, #8-32 wing nuts Slide the filter down the 1.5" #8-32 screws and place the second Silverstone grill on top Mount a Silverstone grill on the other enclosure lid using the 1.5" #8-32 screws and nuts Use one of the Silverstone grills as a template to cut a square of filter material and poke the mounting holes When the welding cable is placed in a slit on top of the unit the automatic start/stop function can be used and the unit will automatically switch on when welding starts and off when welding stops.Mount the fan and chrome grill on the back lid with the 2” #8-32 screws and nylon lock nuts. At low welding fume concentrations, the extraction capacity can be halved, in which situation both motors operate at half speed, thus providing a lower noise level and reduced maintenance. The two motors guarantee an adequate extraction capacity under all conditions. It is also possible to add hoses on the exhaust side to completely remove the filtered air from the area if required. If required an optional activated carbon filter can be placed on top of the main filter to remove smell. The last stage is a High Efficiency Particle Arrestor HEPA 12 which guarantees a filtration efficiency of 99.9% under all circumstances. The large area of the main filter provides a long life and a constant high efficiency since filter cleaning does not have to take place very frequently. When the welding fumes enter the unit they first pass a metal pre-separator, then the fumes flow through a aluminium pre-filter and into the main filter which has a total area of 12m2.
