Scrubber Models




   Scrubber Model       
   Your choices are...
 
      
 
   Building / Enclosure
 
     The scrubber is housed in its own building or enclosure.
 
   Portable
 
     Wheels, size and/or handles make scrubber suitable for easy transportation.
 
   Skid / Base Plate Mounted
 
     Scrubber on skid or plate positioned on the floor. These frequently contain transport features such as forklift slots.
 
   Trailer / Truck
 
     The scrubber is mounted on a trailer or truck.
 
   Other
 
     Other unlisted, specialized, or proprietary mounting options.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Orientation       
   Your choices are...
 
      
 
   Horizontal
 
     Also known as crossflow.
 
   Vertical
 
     Also known as counter current.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Applications       
   Your choices are...
 
      
 
   Abrasives
 
     Abrasives are substances that are used for grinding, honing, lapping, superfinishing, polishing, abrasive blast cleaning, pressure blasting, peening or barrel finishing. Abrasives include natural materials such as broken up nutshells, sand, garnet, emery, corundum and diamonds; and electric furnace products like aluminum oxide, silicon carbide, and boron carbide, as well as glass and various metallic abrasives.
 
   Coolant / Oil Mist
 
     Units are capable of filtering coolant smoke and mist from metal finishing and forming processes, and machining oil mists.
 
   Explosive Media
 
     The unit is capable of filtering explosive dusts, mists, and/or fumes.
 
   Fine Powders
 
     Fine powders can include carbon black, talc, pigments, oxides, and plastic compounding dusts.
 
   General Cleaning
 
     The unit is designed for general cleaning applications.
 
   Litter Pick-up
 
     A heavy-duty vacuum unit designed to accommodate large hoses for litter pick-up.
 
   Non-free Flowing
 
     Collection of non-free flowing or sticky powders and dusts.
 
   Metalworking Chips / Fluids
 
     Collecting metal scraps poses a potential health hazard to fabricated metal workers due to the oils, lubricants, and coolants that must be collected with the metal. Once picked up by an industrial vacuum cleaner, these metalworking fluids (MWFs) emit harmful aerosols that may contaminate the working environment, damage nearby equipment, and make floors slippery.
 
   Reclaim / Recycle
 
     The unit is designed to reclaim, recycle, or recover materials for reuse.
 
   Spill Recovery
 
     Spill recovery units are typically large vehicle transport designed to reclaim or recover large spills.  They are often used in fire, aviation, petrochemical and other industrial applications.
 
   Toxic Media
 
     The unit is capable of filtering toxic materials, such as dust, mist, fume, or smoke from the air
 
   Welding Fumes
 
     The unit is designed specifically for the collection of welding fumes or dust; these may include flux recovery systems.
 
   Other
 
     Other unlisted, specialized, or proprietary configuration.
 
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Separation / Filtration System




          Systems for fine removal may only contain a single filtration system (such as a filter bag or cartridge).  However, most units utilize a primary and secondary separation / filtration system.  Furthermore, some units may have third and fourth stage filtration.  All separation and filtration systems used within the unit should be specified.
   Your choices are...
 
      
 
   Venturi
 
     A wet scrubber, or Venturi scrubber, is similar to a cyclone but it has an orifice unit that sprays water into the vortex in the cyclone section, collecting all of the dust in a slurry system. The water media can be recirculated and reused to continue to filter the air. Eventually the solids must be removed from the water stream and disposed of.
 
   Wet Spray
 
     Achieves intimate mixing by passing the contaminated gas through a constriction partly submerged in scrubbing liquor. This creates a spray in which particulate material is scrubbed.
 
   Packed Bed / Column
 
     A common type of gas absorber in which scrubbing liquid is dispersed over packed columns containing packing material. This design provides a large surface area for gas-liquid contact.
 
   Dry Injection
 
     An air pollution control system that injects a dry sorbent into an exhaust stream.
 
   Dry Spray
 
     An air pollution control device for removing acid gases where an alkaline slurry is introduced into the gas stream and the pollutants absorb into the droplets and react. The droplets dry in the gas stream leaving particulate matter, which is collected by a downstream particulate control device.
 
   Circulating Fluid Bed
 
     A fluidized bed system that has high air velocities (as high as 30 feet per second) and fine particle sizes.  As a result, the fluid bed is less dense (35 pounds per cubic foot) and has no well-defined top surface.  Large quantities of bed material are recaptured from the gas stream and recirculated back to the furnace to maintain bed inventory.
 
   Other
 
     Other unlisted, specialized, or proprietary configuration.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Performance Specifications




   Airflow
 
     The velocity of the air stream created by the vacuum producer.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Efficiency
 
     Refers to the efficiency of a filter system to control or eliminate contaminants.
 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Minimum Particle Size Filtered
 
     The minimum particle size that the unit is capable of filtering.
 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
Features




   Cleanroom Vacuum
 
     The unit is designed specifically for cleanroom applications.  Most cleanroom vacuums will be equipped with a HEPA filter or better.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Continuous Duty
 
     Continuous duty units are rated for 100% duty cycle (constant use).
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   HEPA / ULPA Filters
 
     High efficiency particulate air (HEPA) filters are replaceable extended-media dry-type filters in a rigid frame having a minimum particle collective efficiency of 99.97 percent for a 0.3 micron particle, and a maximum clean filter pressure drop of 2.54 cm (1") water gauge when tested at rated air flow capacity.

Ultra low penetration air (ULPA) filters are extended media dry filters in a rigid frame that have a minimum particle collection efficiency of 99.999 percent for particles greater than or equal to .12 micron in size.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Instrument Panel
 
     The unit is equipped with an instrument panel for user operation.  The instrument panel may be equipped with an alphanumeric keypad, gauges, safety switches, on-off switches, or timer controls.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
