HERR mobile stand-alone mechanical exhaust systems have a stratified series of filters. The standard configuration uses a pre-filtration metal membrane, a main filter, an ultra-fine filter and finally an activated carbon filter (optional). Further customization of the filters can be performed to select filtration characteristics specific to your goals and exhaust.The main filter has high capacity and high precision for capturing small particles. A maintenance alarm warns users when the filter is saturated. The system does not require access to compressed air (as with other systems) or internal ducting. The cleaned air is recycled back into the work environment. Systems are painted with an anti-UV powder coating. They have a solid metal sturdy structure and are suitable for harsh working environments.

Mechanical exhaust systems, both mobile and fixed, can handle 1-2 flexible or rigid exhaust arms ranging in length between 2-8m long. The mobile exhaust systems are designed to be compact, light, and flexible to meet a wide range of exhaust and dust purification needs. Fixed exhaust systems can be installed directly on the factory walls or with an optional, floor mounted support column. The systems have a small foot print and are mounted high enough so that they are generally not in the way. Fixed exhaust arms are available in many lengths and can be up to 8m long, longer with a boom arm.
