Scrubbers are air pollution control devices that use liquid to remove particulate matter or gases from an industrial exhaust or flue gas stream. This atomized liquid (typically water) entrains particles and pollutant gases in order to effectively wash them out of the gas flow. In comparison to other air pollution control devices, scrubbers are very multidisciplinary, with the ability to remove solids, mists, and gases simultaneously while also providing cooling. They are also capable of handling explosive and flammable gases safely. However, scrubbers suffer from high levels of corrosion and produce slurry waste streams which are less convenient for recycling and disposal.Scrubbers are devices that use a liquid (often water) to capture and remove pollutants. Through a nozzle or orifice a scrubbing liquid is atomized and dispersed into the gas stream. The droplets entrain and capture dust particles through agglomeration, adherence, or encapsulation. This effectively increases the size and mass of the particles, making them easier to collect in a subsequent filter or separation process. The scrubbing liquid simultaneously absorbs and neutralizes gaseous pollutants. Suspended liquid is typically recovered in mist collectors and recycled through the system.Many air scrubbers, wet scrubbers, and gas scrubbers are available with pre-filters or final filters to further reduced emissions. Pre-filters are installed upstream of the scrubber intended to catch larger particles. While the scrubber itself would be able to remove these larger particulates as well, their removal allows the scrubber to be designed to focus more keenly and effectively on smaller particulates. A final filter is often installed downstream of the scrubber, and is intended to catch fine particles that were not removed during the scrubbing process.   Design Considerations Pollutant Targeted Removal Efficiency Process Conditions (i.e. flow rate, temperature, concentration)   Effective Scrubber removal efficiency is achieved by ensuring the appropriate contact time between the gas and the scrubbing liquid occurs. These systems incorporate a scrubbing vessel with a system fan, recycle pump, instrumentation and controls, mist eliminator, and exhaust stack. Packed Bed Scrubbers include random packing to facilitate gas to liquid contact. Exhaust gas enters the scrubber where it contacts the scrubbing fluid. The fluid captures the pollutant and is collected for discharge or is treated for reuse. Some of the more common industrial applications include chemical processes, metal finishing process, semiconductor manufacturing and many other industrial operations generating fumes and gases.

This is one of the most technologically advanced grossing stations available. This unit combines paramount laboratory work space ventilation and a back-saving elevation feature. Designed with a work surface that elevates physicians and technicians of varying heights can find the most agreeable elevation to perform their duties without back strain. Complimenting this health benefit, back draft ventilation system eliminates respiratory strain by directly ventilating the work surface.     Features Work surface: Recessed stainless steel Removable polyethylene cutting board - color white, 4 leveling pads Washable ruler with inch & centimeter markings.Ruler is located on the inside lip of the workstation Magnetic tool bar holds instruments when not in use Stainless steel c-fold paper towel dispenser Energy saving, long life LED lights GFCI electrical receptacle Exhaust duct connection: 5" diameter stubs with flexible ducting Ventilation: Back draft ventilation designed to safely and efficiently remove formaldehyde fumes and hazardous chemical vapors. Equipped with a factory installed exhaust duct which can be connected to any in-house ventilation system. All plumbing and electrical work accomplished at factory Only trade hookup required 14" Stainless steel shelf Bin: Organizer Bin - 1 small stainless steel; Organizer Bin - 1 large stainless steel

GV Technology portable fume extractors are available in several different sizes and air volume configurations. These units are equipped with heavy-duty casters, portability handles, and a variety of source-capture flex arms. Two flexible hose options are available and can be configured as single or multiple operator models. Accompanied by high-quality filtration media, these systems are designed to work with a variety of applications where fume and particulate need to be captured and purified. Typical filtration combinations include HEPA and Activated Carbon filters or specialty-blended media [Acid Gas, Mercury, Aldehyde, Ammonia]. These compact units allow significant operator control through mobility and source-capture placement   Features Highly compact design with filtration unit mounted on wheels to provide mobility Low maintenance fume extraction system with cartridge type filter Higher filtration area Auto cleaning with compressed air reverse pulse jet arrangement Blower arrangement at cleaner side reducing problems in the impeller & motor assembly Flexible suction arm provides freedom of adjusting the suction Joint at any convenient position   Benefits Improved shop-floor environment with clean air Ensure highest worker health and safety Protection from harmful fumes for production equipment & manufacturing processes Higher productivity with lesser disturbances on shop-floor

A dust collection system is used on production floors to improve air quality by removing dust and other particulate matter from the air and environment. GV Technology manufactures a wide range of dust collectors to match your site specific requirements. We have both bag house filter as well as cartridge filter dust collectors. We have the very large reverse pulse jet bag house machines which are designed to collect large volumes of dust but also manufacture portable dust collectors for individual production machines. Working First, the dust must be captured. This is accomplished with devices such as capture hoods to catch dust at its source of origin Second, the dust must be conveyed. This is done via a ducting system, properly sized to maintain a consistent minimum air velocity required to keep the dust in suspension for conveyance to the collection device Finally, the dust is collected. This is done via a filter media and a collection tank    Components Hood to capture the dust at its source Duct system to convey the dust Dust Collector, which consists of Centrifugal blower to provide necessary suction in the hoods and maintain the transport velocity in the ducts Fabric separator or cartridge filter with filter cleaning mechanism if necessary to separate the dust from the air stream Collection tank to store the collected dust   Factors to be considered Material to be collected (along with sample) Median particle size, size distribution Volume of material to be collected Nature of material Abrasive/Corrosive/Sticky/Explosive/Flammable etc. Hoods / Downdraft Tables Located so there is minimum hindrance to operator and provides easy access for service

The blower head is cast and machined as a single piece with equally spaced bearings configured specifically to provide even loading from the belt drive. This design is fundamentally different from other belt driven units and allows the belt to be run at a tension much lower than other belt driven units, therefore resulting in much lower loads on all parts of the assembly.The single piece construction also guarantees correct alignment of the integrated precision spindle. The outcome is a more robust and efficient assembly, which both improves manufacture and enhances stability and reliability, essential with operating speeds up to 20,000 rpm and deliveries of 1200 CFM. In addition, each spindle is assembled in a clean-room environment, away from the general factory. Once fully assembled, each blower is operated at full speed after final assembly. Technical Details Flow rates up to 2040m³/hr Pressures up to 250mBar 5.5kW to 18.5kW Reliable, maintenance-free operation
