Acid Fume Scrubbers

Acid Fume Scubbers 16000 CFMThe acid fume scrubbers offered by Modutek remove chemical mists and droplets from the exhaust air of installations using acids for etching and cleaning. The high chemical removal rate of the scrubbers lets manufacturers and research labs avoid discharging of hazardous fumes that can harm workers and corrode equipment. The wide range of air handling capacities of Modutek’s scrubbers and the company’s custom design capabilities make it possible to meet a wide variety of needs for customers with particular applications.

Modutek’s acid fume scrubbers work by exposing contaminated air to a chemical solution. The acid in the air dissolves in the solution and is neutralized. Exposing the acid fumes to as large a surface area of neutralizing solution as possible is the key to an efficient operation. In Modutek’s fume scrubber design, the fumes pass over a wet packed bed. The packing material is made by industry leader Lantec and has an extremely high surface area. The packing material surfaces are covered by the neutralizing solution resulting in a removal rate for the fume chemicals that can reach 99 percent.

High efficiency and low cost of ownership are supported by a flexible design and a complete set of operator-friendly features. The air handling capacity of the fume scrubbers ranges from 500 to 25,000 CFM and water consumption is reduced to a minimum by using a water recirculating system with pH control. Construction is of black polypropylene with UV protection and with a NEMA 4 control cabinet. The scrubbers are built with double containment for extra safety and a bottom drain for ease of maintenance. A complete set of flow and pressure gauges combined with scrubber water level control and metered water discharge give the operator a complete picture of the process. A demister section is included and structural and seismic certification is available.

Modutek’s acid fume scrubbers are suitable for many applications including wet processing stations, tech benches, fume hoods, plating stations, precision cleaning stations and acid exhaust hoods.
