Welcome to Hahn's Rapid Air Drying Systems

Rapid Air Drying Systems is a cutting edge technology used to significantly reduce the amount of drying time required for waterborne coatings. Rapid Air Drying Systems was invented and developed by Hahn Marketing LLC, a firm that also owns Hahn Collision. The Rapid Air idea was formulated when Hahn Collision converted over to spraying with waterborne coatings and saw production decrease due to the amount of flash time for waterborne paint. The Rapid Air Drying System actually helps increase production by significantly reducing the flash time required by the new waterborne coatings.

As collision shop owners, we know the Rapid Air Drying System is the perfect solution for your collision or body shop needs. Retro fitting the Hahn's Rapid Air Vortex System to your old or new spray booth is easy and it will allow you to maximize efficiency and greatly reduce cost.

What Are Waterborne Coatings?

Most coating manufacturers have developed waterborne color coatings to comply with emissions requirements. Future changes in air quality regulations are expected to lower the volatile organic compound (VOC) limits allowed in coatings and require the use of waterborne refinish coatings. Waterborne and low-VOC coatings technology continuously improves to meet the needs of the industry while maintaining regulatory compliance.

Custom Designed Solutions

We design systems to fit most standard booths as well as accommodate custom tunnel booths for fleet business.

The "Hahn's Rapid Air Drying" Retrofit System

We at Hahn's Rapid Air Drying Systems have designed and can supply an inexpensive way to retrofit almost any Spray booth, whether a Downdraft, Side-draft and or Flow-thru booth. All booth design sees significantly improved in drying times with the installation of the Hahn's Drying system.

One would expect that just moving a lot of air over freshly paint surface would cause the paint to dry more quickly. This is true to some extent, but because in the drying phase in a normal booth a layer of stagnant air always stays near the freshly painted surface. In addition, sprayed paint has small ridges and valleys that cannot be seen with the naked eye but exist on the surface, these imperfections trap moisture. In a normal down draft spray booth a smooth flowing layer of air slows the removal of water in waterborne paints and VOC paints preventing it to not dry quickly. What is needed, is a method to cause that stagnant air that was just flowing around the car panels to mix with the trapped air on the wet panel surface. This dead air needs to be "whooshed" away, to expose dry air to the newly painted surface.

What RapidAirSystems does is create a "chaotic - random" air movement in the spray booth during the drying cycle. This random airflow exposes much dryer air to the surface to be dried; it breaks up the trapped air layer on the panel surface and allows fresh dry air to contact the paint. A disruption of the laminar flow of the air is what the Hahn's Rapid Air Drying System does and it does it cost effectually.

Added benefit to the Hahn's Rapid Drying system:

  • 2 micron filtered air is dispensed into the booth.
  • The fresh filtered 2-micron filtered air is injected into the booth. This air is heated up in the Ring centrifugal pump with temperature rises between 10 and 25 degrees F allowing it to hold more moisture. Reducing Gas costs.
  • The Hahn's system uses NO SHOP COMPRESSOR AIR
  • The system is very quiet. The RAD system is inexpensive operate.
  • Systems is scalable to whatever is required for your operation, ----from 1 Hp to 50 Hp.
  • The system is easy to install in most booths in less than 4 hours and can be done by shop owners or mechanical installer if desired.
  • The 120 volt systems (1 Hp and 1.75 Hp ) can be plugged into a normal dedicated 20 amp outlet.
  • The 2.5 Hp Units can be ordered in 230 VAC Single Phase or 230 VAC or 440 VAC 3 phase.
  • Complete air speed control with OPTIONAL Variable Frequency Drive on 2.5 Hp and larger units. This VFD option allows the painter to custom adjust the vortex speed for any requirement.
  • Quick return on investment cost - Cost saving is process cycle time and Heating gas/electric are realized.
  • The Hahn's System was designed by a collision shop owner. It is easy to install, either by a mechanical contractor or owner can do it himself. A licensed electrical contractor should complete electrical installation. Some systems can be plugged in to a 20 amp 120 VAC wall socket.
  • Drying times are significantly reduced. -----Thereby increasing production.
  • Even panel temperatures throughout the booth because of the Vortex action of the air stream keeps the booth at the same temperature. ---- NO Cold OR HOT spots in the booth when RAD is on.
