Dual Throat Venturi Air Scrubber

Remove Airborne Particulate Matter

The Monroe Dual Throat Venturi Air Scrubber is designed to remove both heavy and light airborne particulate matter from exhaust systems, as well as flue and process gasses. The Monroe Dual Throat Venturi Air Scrubber is a completely self contained unit that needs only to be connected to normal plant electrical, water and air systems.

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 Venturi Air Scrubbers are currently operating continuously at high efficiency in many types of industrial installations throughout the United States, Mexico and Canada.

Independent laboratory tests have shown that many of these units are removing various types of airborne particulate at efficiencies up to 99.9%, even on heavy particulate loads.

A High Volume Water Injector

The Monroe Venturi 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.

Double Row Moisture Eliminators

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.

Minimum Wash Liquid Requirements

Waste water disposal problems are eliminated under normal operating conditions. Each unit has a self-contained wash liquid reservoir and recirculating pump. An automatic water valve replentishes wash liquid lost through evaporation.

Optional automatic drag conveyors for removal of heavy, settled particulate and oil recovery units provide additional wash liquid cleaning for more efficient operation.

Materials of Construction

Monroe Dual Throat Venturi Air Scrubbers are constructed of mild steel for most applications. However, where the intended use will involve corrosive or highly abrasive contaminants, other construction materials such as stainless steel or reinforced fiberglass, as well as special coatings are availiable.

Moisture eliminators also are constructed of materials suitable for the intended application, including polyethylene or stainless steel.

Electrical Controls

Complete electrical controls are available to meet customer specific requirements.

Many Configurations Available

Monroe Dual Throat Venturi Air Scrubbers can be configured to meet specific needs. Units can be equipped with drag conveyors to remove heavy, settled particulate and oil recovery units to remove accumulated oil.
