VENTILATION GLANDS
Dust and dirt protection
Keeps water out and
Lets air circulate effectively
Benefits of Bimed Cable Glands with Integrated Ventilation.
• Advantages of cable gland and pressure balance device combined in one product.
• Heat generated by electrical and electronic components in an enclosure, as well as
fluctuating outside temperature, result in pressure differences.
A semipermeable membrane inside the device allows air and humidity to leave the
enclosure, however, doesn't allow dirt and water to enter from the outside.
• Properties of the membrane stay the same independent of cable diameter and torque.
• These polyamide cable glands have higher strain and torsion relief at lower cap nut
tightening torque compared with same size standard cable glands.
• Hights of PA 6 cable glands with integrated ventilation are significantly less and have smaller
volumes than same size standard cable glands. Suitable for smaller spaces.
• Comply with EN 50262 and EN 60335.
• IP 66 and IP 67
• Custom specifications are available on request.
• Air permeability of cable glands with integrated ventilation:
As an indicative information.
The change of the air permability in relative with the differential
pressure (ΔP) is showed in the following table for
Pg 13,5 Brass Ventilation Gland.
ΔP 50 mbar 30 l/h
ΔP 100 mbar 66 l/h
ΔP 150 mbar 102 l/h
ΔP 200 mbar 138 l/h
ΔP 250 mbar 174 l/h
ΔP 300 mbar 216 l/h
(ΔP is the difference between interior/exterior enclosure pressure)
