Rückschlagventil für Klimaanlagen

[Features]
· In highly airtight housing, external air reverseflows indoors through the drain hose due to indoor/outdoor pressure differences. A burbling sound is generated at the section where the drain water accumulates.
The check valve enables smooth discharging of drainage water while simultaneously suppressing any burbling noise.
· It also helps prevent insects and external air from seeping in.

[Applications]
· As a room air conditioner mechanism for silencing unwanted noises and preventing insects from getting in. (for DHQ exclusively).
