When filtration is required, RAPID™ 7500-Series air turnover units offer various filter types. Aluminum mesh permanent filters, 30% efficient pleated type filters and 30% efficient polyester filters are available. Easy loading filter racks allow for quick filter replacement.


For applications requiring temperature and humidity levels lower than the performance parameters available with outdoor air alone or with evaporative cooling, RAPID™ 7500-Series air turnover units offer a broad range of cooling options.

Cooling options can be added by simply installing coil sections equipped with the appropriate cooling coils and a condensing unit or chiller. The versatility afforded by the coil section enables you to utilize DX refrigerant, chilled water or other types of cooling coils in your system.
