Reduce Sound Level with EXAIR’s Flat Super Air Nozzles

EXAIR’s Flat Super Air Nozzles have been blowing away the competition since 2003.

The patented design of EXAIR’s 1” and 2” Flat Super Air Nozzles make them a highly efficient option when seeking a powerful, flat airflow. A precise air gap across the width of the nozzle provides a forceful stream of high velocity, laminar airflow without consuming high amounts of compressed air and also resulting in a greatly reduced sound level compared to some of the alternative flat nozzles available in the market.

EXAIR’s Flat Super Air Nozzles are safe, reliable, and efficient. Here on the EXAIR Blog we frequently discuss dead-end pressure as explained in OSHA Standard 1910.242(b). This directive states that the when compressed air is used for cleaning purposes, the dead-ended pressure must not exceed 30 psig. When pressures greater than this occur, there is potential for an air embolism.

EXAIR’s Flat Super Air Nozzles cannot be dead-ended, which allows us to operate at pressures well above the 30 psig limit. Some competition markets their nozzles as “Extremely Quiet”, but a deeper look into their performance specifications shows that the published sound level reading was taken at a pressure of 29 psig. They must use a pressure of 29 psig because the nozzles are not OSHA compliant at pressures exceeding 30 psig. For the same competitive nozzle, there is no path for air to escape if the nozzle were to be dead-ended or pressed up against the skin. At 29 psig, the nozzle simply isn’t very effective as it doesn’t provide enough force for most applications. This very same nozzle, when operated at 80 psig, actually has a sound level of 85 dBA.

EXAIR’s Model 1122 delivers more force, more efficiently, and at a sound level of just 77 dBA at 80 psig. Remember, sound levels are expressed in dBA as a logarithmic function. This represents a decrease in sound level by 60%! If you’re looking for a means of reducing sound level in your plant, EXAIR’s 1” and 2” Flat Super Air Nozzles are just what you need.

In addition to being very quiet EXAIR’s flat super air nozzles integrate a shim used to adjust the air gap, which changes the maximum airflow and force. Thicker shims will produce more force and flow, while a thinner shim would do just the opposite.Some applications require more force and some require less, which is not always achieved through simple pressure adjustments so the shims provide the flexibility needed for success.
