Product Description
A Vortex Tube without attachment at the cold and hot end are quite loud. The cold end muffler reduces the exhaust noise up to 10dbA and is a standard part of special vortex tube packages, such as the Tool Cooler, Adjustable Spot Cooler and Mini Cooler Systems. The hot end of a vortex tube also exhausts hot air which gives exhaust noise.
There are two sizes of hot end mufflers. One size fits the small and medium vortex tube and threads over the hot end with the adjustable screw. The other larger size threads over the hot end of the large vortex tube with the adjustable screw. Sound reduction would be in the range of 3 dBA.
