STEGO Pressure compensation device (stainless steel M40, aluminium M12) DA 284


DA 284 | IP66 stainless steel | IP67 aluminium
Passive pressure compensation device for enclosures in environments with requirements: food-safe and corrosion-resistant. Evens out temperature-induced pressure differences between the inside and outside of the cabinet. Humidity escapes through a watertight membrane. Condensation is prevented from forming.
  • Thread sizes: M12 aluminium and M40 stainless steel
  • NBR membrane
  • Prevents ingress of water and dirt
  • Protection type IP66 V2A, IP67 aluminium

Overview Technical Data

5 Nm
~ 9 mm
sealing gasket NBR
waterproof membrane
M40: Ø 58 x 31 mm, M12: Ø 17 x 21 mm
-35 to +80°C (-31 to +176°F)
Material adheres to limit values in accordance with RoHS3

Make cut-out Ø 40.5+0,5mm in enclosure wall and mount pressure compensation device with nut. Please make sure that the sealing gasket is put in place on the outer side panel of the enclosure. For optimal pressure compensation we recommend to use two devices on opposite sides towards the top of the enclosure.
