5ATM Pressure Vent | Electronic Vent: Wearable Device

IPRO Home Application Portable Electronics VentsSmart Wearable Device Pressure Vent 5ATM


The proportion of smart wearable products, such as smart bracelets, watches and TWS earphones has gradually increased. Diversified application scenarios have given rise to a strong demand for waterproof smart wearable products. With natural hydrophobic properties thanks to its multi-fluorine molecular structure, IPRO pressure vent is mainly made of ePTFE and installed at the pressure relief hole of wearable products to equalize pressure, and enable the wearable product to be immersed in water at the depth of 50 meters without breaking.

Product Application : 5ATM


With the popularity of intelligent wearable products, traditional wearable products (such as mechanical watches, etc.) are gradually being replaced. Smart wearables have also derived from single-function bracelets into a variety of products, including smart sports watch, children’s watch, TWS headphones, and health monitoring watch for the elderly, etc.


Wearable products are used daily and widely, thus are inevitably exposed to hand sanitizers, sweats, rainwater, and other liquids. Therefore, being waterproof and resistant to corrosive liquids becomes vital for wearable products. Today, waterproofness has become a standard function of wearable products. Health monitoring watches, children’s watches and sports watches are often used during swimming and diving. Diving-grade of 50m waterproof capabilities has gradually become a necessity for intelligent wearable products.


In order to achieve excellent waterproof levels, the product must be completely sealed. Yet this creates another problem, i.e., heat generated by electronic components were unable to dissipate, leading to raising temperate and pressure, which prevents the speaker from functioning normally. Meanwhile, pressure may cause damage to the components and the sealing structures as well.


The pressure of 50 meters underwater reaches 500kPa, which cannot be withstood by ordinary elastic materials. How to be waterproof in deep water but still remain air permeability has become the most difficult challenges for diving-grade wearable products.


The 5ATM pressure vent has natural hydrophobic properties and amazing porosity. It has both waterproof and air permeable ability which enables wearable products to attain 50-meter diving-grade waterproof capabilities. The product can be immersed in water at a depth of 50m without breaking. Meanwhile, excellent extendibility, resilience and good air permeability allows the product to have good venting performance, even when sealed completely. Equalizing pressure in time could also protect the internal components and the sealing structures. Moreover, it can prevent the speaker from vibrating poorly, and ensure the smooth tone of the product.


With the waterproof and venting protection, consumers will no longer worry about damage from water to the smart phone.

Key Features
  • Pure natural hydrophobic and permeable performance, with long service life;
  • Chemical inertness, resistant to splashes of sweat, soapy water, coffee, sea water and other liquid;
  • Dust-proof Rating: Up to Level 6, preventing dust from entering the machine and damaging the components inside;
  • Operation Temperature: -40℃-+105℃.
