HARLEYSVILLE, Pa., July 12, 2001 — Met-Pro Corporation's Duall Division announced it has received three orders for odor control systems totaling approximately $530,000. All systems are expected to be installed in the company's third quarter.

Two orders are for municipal odor control systems that will provide 99.9% removal of hydrogen sulfide from the clarifier and headworks operation of two municipal wastewater treatments plants. The first order is for a 10,000 CFM fiberglass reinforced plastic (FRP) odor abatement system for a city in the midwestern United States.

The second order is for a 37,000 CFM PVC odor abatement system for a city in the northwestern United States.

Duall also received an order to supply a 9,000 CFM PVC industrial odor control system to a Ohio-based chemical company for removal of odor causing contaminants and mists/aerosols from their production process.

Duall was selected for these projects based on their reputation for superior technical performance and the division continues to be a significant presence in the air pollution control and odor control markets. Customer interest and quotation activity for similar applications appears to be increasing and provides encouragement for the possibility of future orders.
