NEW Saf-Deflat-Aer Screw-On Version

March 8, 2016
New device to drastically reduce noise levels by more than 20 dBA when deflating aircraft wheels.

Kestrel Engineering Ltd is pleased to offer a new simple device to drastically reduce noise levels by more than 20 dBA when deflating aircraft wheels. A Boeing 747 wheel inflated to 195 psi, which is deflated by removing the valve core, can result in an ear-shattering noise level of 117 dBA, which is extremely high by current international safety standards.

If the new Kestrel Engineering Ltd Saf-Deflat-Aer Screw-On version is used to remove the valve core, the escaping nitrogen passes through the integral silencer and the maximum noise level experienced is then only 94 dBA. Within a minute the noise level is reduced to 86 dBA, and after 3.5 minutes it is reduced to 74 dBA. The wheel is fully deflated after 4 minutes.

The Saf-Deflat-Aer Screw-On is easy to use. It contains a connector which is firmly screwed onto the external threads of the Schrader wheel valve. A knob is then used to locate the end of the integral spindle on the valve core. It is then rotated to raise the core off its seat, which results in the compressed nitrogen escaping through the integral silencer.
