EXAIR's Super Air Nozzle clusters are an array of 1/4 NPT Super Air Nozzles on a round manifold which provide force values that are similar to our largest nozzles but at lower decibel levels. These nozzles can be used in areas where low noise levels are the first consideration. All aluminum construction from 3/8 FNPT through 1 FNPT. Force values from 3.2 lbs (1.45 kg) through 9.8 lbs (4.45 kg). Learn More
