Pneumatic solenoid valve - HDI
The Lee company's new Quiet Operation High Density Interface (HDI) is specifically designed to reduce noise factor and increase the
comfort of the patient by using a 3-way solenoid valve. Equipped
with a new "whisper" technology this design bypasses the "inherent
clicking activation sound" of the standard solenoid valve and provides
sound level measurement of less than 37 dBA. Measuring was done
from a distance of 24 inches with a valve cycle frequency of 10 Hz.
HDI design is offered in multiple configurations such as face mount,
plug-in and ported. The noise reduction of HDI makes it best suited
for use in medical applications involving flow of gas or air, like
ventilators / respirators and any other medical devices.
