Walk-In units are used by a wide variety of customers who need to capture dust or fumes but also require operational flexibility to allow work processes to be performed unencumbered. Multi-step processes or customers working on large parts often use Walk-In units to address their dust or fume issues. For example, for finishing processes on large jet engine assemblies or performing multi-step weighing processes of powders and bulk solids. DualDraw has customers in both of these categories using Walk-In units to successfully contain their hazards.
The building blocks of a Walk-In are the modular Power Wall units that house motors, fans, and filtration. Power Walls are typically 4’ W x 4’ D x 8’ H and use the patented DualDraw even-airflow design to generate powerful airflow and capture velocity. Power Walls can be used as stand-alone units that operate adjacent to a dust or fume producing application but are most often linked together along with modular siding and a roof structure for a complete Walk-In Clean Air Station. All sizing is based on customer specifications – a popular Walk-In unit size including the roof and sides is 12’W x 8’D x 8’H. Units come with an optional Regain Air System that employs proprietary slotted adjustable tubes that run along the front sides of the unit. Some other popular options include roof slots to accommodate overhead crane or hoist systems, hazardous duty components to satisfy certain classified environments, filtration alarm systems, and space saving configurations for crowded facilities. Filter systems on Walk-In units are designed to handle the particular hazard and loading requirement specific to the customer. DualDraw will work directly with the customer to understand at a deep level what materials need to be captured. A determination is then made with the customer on the best filter package to address the application.
