air purifiers at work

Independent laboratory tests have shown that many of these units are removing various types of airborne pariculate at efficiencies up to 99.9%, even on heavy particulate loads. A High Volume Water Injector The Monroe Dual Throat Air Scrubber utilizes a high volume wash water injector system that removes airborne particulate by delivering an initial surface inpingement shock to heavy inlet dirt loads. Dual Adjustable Scrubbing Throats High velocity atomization takes place as the inlet air is directed through the fixed and dual adjustable scrubbing throats. The easily adjustable dual throats balance the pressure drop through the air flow system at the start-up or after system changes are made. This design feature eliminates the need for ductwork dampers and blast gates that are prone to particulate build-up and require periodic maintenance. In addition, the increase in pressure drop in the wash zone improves the overall effciency of the system. After passing through the turbulent dual throat wash zone, the air inpinges on the liquid surface, changes direction and then continues through deflectors and to a large, double row moisture eliminator section. Water droplets in the airstream are removed and drain back to the wash liquid reservoir tank. The clean, dry air is then recirculated to the work area or discharged through exhaust ducts.

Recirculate Clean Air In many installations, such as buffing and polishing, metal finishing and grinding foundry operations etc., it is possible to recirculate clean, contaminant-free air back to the work area. This reduces the cost of plant ventilation systems and climate control needs. Proven High Efficiency Monroe Dual Throat Air Scubbers are currently operating continuously at high efficiency in many types of industrial installations throughout the United States, Mexico and Canada. Cartridge cleaningis accomplished by reverse compressed air pulses through a few cartridges at a time, allowing continuous operation without shut-down. These reverse pulses, with a velocity of twice the speed of sound, break away caked dust from the cartridge so that it can drop the collector bottom. Because of slower internal velocities through the collector, media replacement and maintenance labor costs are reduced. Collected oil mist and solids are continuously drained from the media without shut-down, significantly prolonging filter life and lowering overall operating costs. The Monroe Fiber Bed Mist Collector removesparticles as fine as 0.3 micron. While normal filters permit these particles to re-entrain into the outgoing clean air, Monroe''s self-draining filter is designed to prevent oil re-entrainment and recirculate clean air to the atmosphere.

The Monroe Spiral Tube Collector features heavy gauge mild steel and stainless steel construction for years of efficient performance. Welded seams and built-in lifting hooks provide rugged durability. HEPA Type Filters The Monroe Spiral Tube Collector is available with specially constructed HEPA type fiberglass filter cartridges as the optional final filter system. These filters are normally supplied with a 95% efficiency rating at 0.3 micron. Final filters have a long service life because the majority of airstream contaminants are removed by the spiral tube stage. Slide-out design for easy filter removal is included. Special Features Large, easy to open access doors for all serviceable areas. An AMCA rated fan on the outlet side of the collector with either a direct coupled motor or a "V" belt drive. Quiet operation. Rubber isolation fan connection and sound attenuators are available if needed. Under 80dba is typical. Integral differential pressure gauges are available to indicate when filter maintenance is required. Complete electrical controls are available to meet customer specific requirements. Monroe Spiral Tube Collectors can be configured to meet specific needs with numerous options available to provide maximum efficiency in any application.
