Air Filtration

Air filtration on construction or restoration sites are key to keeping to environment safe for workers and inhabitants. Our HEPA and Aerospace air filters can remove odors, germs, allergens, chemicals and humidity. They are perfect for restoration jobs to remove harmful particles and chemicals from the air. Ducting options can provide the combination of negative or positive air flow. This will help to control an area and containment air scrubbing at the same time.


Moisture getting into your construction site or home can be devastating to the structure, so in the case of water restoration or construction it is a good idea to have proper dehumidification on site. Our dehumidifiers can remove moisture from the air and can be paired with our large circular or floor fans to make sure that no moisture is left behind. Our air scrubbers and hepa filters can also ensure that your air stays clean and safe when performing remodels, new construction or restorations.

Fans & Air Movers

When working in construction, restoration or special events air movers and fans could be helpful to keep air flowing. Our large range of fans and air movers can provide you with air circulation that you need. The sizing of our fans range from large 30ft round fans, to small carpet blower fans. Our experienced sales representatives can help you decide which products would be right for your situation.

Sizes range from our small thaw box to our larger hydronic ground heaters.
