Quietly cool electronics inside enclosures while keeping out rain, snow, splashing water, and dirt. These vortex tubes have mufflers on both the hot and cold air outlets to reduce noise. They use compressed air, making them a lower-maintenance choice than electric air conditioners. Adjust the ducting to spread air evenly in your enclosure or to cool specific parts. A filter captures and drains moisture from the air to protect your equipment from water damage.
