Soldering Fume Extraction

by DiversiTech     based in Montreal, QUEBEC (CANADA)

Soldering fumes are Unbreathable. Soldering enables the joining of metal parts by melting a filler metal to attach wires and other metallic components. The fumes generated from melting solder especially solder containing Lead or Tin present are dangerous and require local ventilation to remove harmful smoke from the work area. Soldering application need to be properly ventilated to prevent toxic fumes from reaching the worker`s breathing zone. There are a number of different industries such as the electronics assembly industry and electronics repair comapnies who must deal with the hazards of solder smoke. Fumes created by automated PCB soldering including wave soldering machines, handheld soldering irons, torch brazing and furnance brazing are often ignored because of the small volume of smoke generated. However, these applications still require careful consideration as dangerous fumes can impair employee’s respiratory tracts depending on the filler metals used. Because manual soldering applications require working with tiny components, workers end up positioning their heads right above toxic rosin or lead solder fumes with a direct exposure into their throat, nasal passages and lungs, and as a result, they can experience respiratory complications. Rosin irritation can cause various side effects and the inhalation of lead fumes is carcinogenic. As lead oxide smoke collects in your lungs, it can be transferred into your bloodstream. Diversitech recommends installing soldering fume extraction equipment to prevent the inhalation of dangerous fumes. These ventilation units will not only protect each person working at a soldering station when installed and positioned correctly, but they will also prevent fumes from contaminating other worker’s lungs.?

Painting & Coating

by DiversiTech     based in Montreal, QUEBEC (CANADA)

Paint fumes are Unbreathable. Spray Painting VOCs and Powder Coating dust are both harmful pollutants which are produced during painting operations. The volatile organic compounds (VOCs) emitted from paint can cause respiratory issues and require proper ventilation to remove harmful gasses from the work area. Powder Coating lines and spray painting produce dangerous fumes and dusts which need to be filtered or exhausted outside your facility. Industrial coatings and chemicals can produce toxic VOCs and foul odors which can effect worker`s health and reduce productivity. Some of the most common coatings are polymers which include polyurethane, epoxy and moisture-cure urethane. Many different industries required the use of glues, adhesives, solvents and different chemical agents in their production process, but are unsure of the best way to handle this nuisance. Exhausting fumes outside may be an option when VOCs are extremely dangerous and odorous but companies must also comply with EPA guidelines which regulate which gases can be emitted. In cold climates and in air-conditioned facilities, capturing, filtering and recirculating fumes can provide huge energy savings preventing costly heat loss and energy intensive air makeup systems. Utilizing activated carbon granules can allow operators to filter VOCs and odors from painting and cutting applications. Different quantities and types of carbon modules are required depending upon the contaminant. Contact Diversitech with an MSDS sheet detailing your chemical`s characteristics for an evaluation of your workplace air quality problem.?

Odour removal units for professional kitchen ventilation

by Dimtech S.A     based in Keratsini, GREECE

Our company has odour removal units for professional kitchen ventilation, for grills and food preparation areas generally. The operation of the unit is based on chemical or electrostatic filters or a combination of both. The kitchen unit KDSA (with chemical filters) series, neutralizes particles, soot, odors, grease and moisture completely. KDSA units for kitchen ventilation are installed in the cooker hood and are connected with the kitchen areas that produce smoke or where there is smoke and odors such as in kitchen funnels or in washing facilities. The air stream in the deodorizer passes through a set of filters where particles, grease, soot and odors are removed.

Welding Fume Extraction

by DiversiTech     based in Montreal, QUEBEC (CANADA)

Welding fumes & gases are Unbreathable. Nonetheless, welding is perhaps the most common industrial process and necessary anytime the joining of metals is required. Regardless of the welding equipment type or technology, the simple process of melting metal and filler materials creates poisonous fumes and gases. ? Different types of welding processes present unique challenges to adequately handle airborne fumes. Robotic welding equipment and other automated welding systems produce a high volume of welding fumes and sparks and need to captured by a heavy duty robotic welding hood. Moreover, manual stick welding typically produces a high volume of smoke and often requires a self-cleaning fume extractor to avoid overwhelming the filters.? Lighter duty applications like MIG welding generally produce less particulate and light-duty TIG welding generates the least amount of smoke. It is important to not only consider the type of welding process but also the work piece material in order to select the correct filtration media for your application. HEPA filters are recommended for stainless steel welding, Nanofiber filters for Aluminum and parts containing higher levels of Manganese. Polyester filters are appropriate where rust inhibitor, lubricants and coatings create an oily smoke as these filters can be washed in water. Diversitech offers a complete line of fume collection machines from compact welding fume extractors to central welding fume filtration systems. We specialize in engineered solutions and our engineering team is experienced in selecting the best equipment and filter media for your particular application. We can present you with detailed technical drawings demonstrating several potential layouts and solutions including costing, installation and start-up expenses. ??

Depuration of oil and emulsion mists

by GGE srl     based in Rio Saliceto, ITALY

In machine shops, where the production is centered on the use of machine tools, one of the most common problems is the restoration intervention aimed at limiting the presence of oil or emulsion fogs. As a matter of fact, since machine tools work at very quick production rhythms, they widely use lubricating fluids such as oil or oil emulsions and water.

Whether it is geographic shifts in demand or production, or challenges brought by energy or raw material costs, companies continue to develop their processes and facilities to meet them. Alongside these changes companies have also realised the requirement to minimise downtime due to unplanned maintenance and protect workers from exposure to toxic or flammable gas hazards.

Testing Fume Hood Flow Dynamics using SF6 as a Tracer Gas

by Spectro Scientific     based in Chelmsford, MASSACHUSETTS (USA)

A safe laboratory environment requires an effective method for clearing toxic material from fume hoods. Since all handling of toxic materials is completed in these hoods, it is critical to have a procedure to evaluate their operation to assure adequate protection for laboratory workers. The InfraRan Specific Vapor Analyzer, factory calibrated for SF6, is an ideal instrument for measuring fume hood efficiency in accordance with ASHRAE and other standards. Manufacturers identify the flow dynamics (factors that affect air flow in the hood and performance with air) using the ratings AM (as manufactured), AI (as installed), and AU (as used). A fume hood evaluation conducted under its operational environment is critical, as these tests will indicate any installation shortcomings as well as direct workers in proper laboratory hood techniques.
