HUESTIS Down Drafter Air Wipe

The "Down Drafter" was developed in response to the needs of specialized extrusion, where blow back of liquids has to be minimized and avoided for improved drying without disturbing the environment around it.

It has our patented nozzle jets mounted both in the front and rear of the body with a center drain in the bottom that is threaded, allowing the customer to install a fitting to connect to piping or a flexible hose to return liquid back to their process supply without using an additional enclosure, if desired.

It also allows the customer to gang multiple units together, whilst minimizing liquid blowing back onto the product from the previous-in-line air wiper.  Lastly, it performs better at higher speeds than a standard air wiper.  Using the metering valve, you can tune and balance the air flow between the jets for maximum drying effect on each product or profile.  The down drafter is available in sizes up to 1 1/4 inch (31.7mm) diameter.

FEATURES

• Reduced blowback / cleaner drying environment
• Return of removed liquid
• More efficient drying due to two rings of air nozzles
• Faster line speeds possible

MAX AIR FLOW / MINIMUM NOISE

• Most manufacturing plants already use compressed air, making conversion to Air Wipes both quick and cost effective.
• Very often, a change to Air Wipes results in reducing the number of compressors on line.
• Air Wipes require only a fraction of the horse power needed to generate the electrical requirements of a centrifugal blower.
• Air Miser’s controlled air flow produces much lower noise levels compared with open lines or adjustable models.
