Miniature breather prevents pressure build-up in equipment and can withstand driving rain or even total immersion in water for long periods.
Brownell has introduced a compact breather that prevents pressure build-up in equipment and can withstand driving rain or even total immersion in water for long periods.
Lightweight materials used in the manufacture of specialist electronic products often give designers a dilemma of either restricting the applications or increasing the strength of the enclosure.
Many electronic products produce heat which can cause a build-up of pressure within their enclosure, and without adequate venting the lightweight material could fracture.
Brownell's Mini Immersion Proof Breathers, manufactured in plastic and metal for aggressive environmental applications, allow equipment to breath but prevent water and dust ingress in corrosive and hostile conditions.
They are capable of passing high flow rates of air resulting from rapid changes in temperatures and pressure.
The Mini Immersion Proof Breathers will find applications where equipment, such as sealed keyboards and communications instruments, are used in hostile areas including medical laboratories, industrial plants and high or low temperature environments.
Mini breathers can be fitted to desiccant tubes which are capable of removing moisture and other contaminates including hydrocarbon vapours.
The breathers can be screwed in place or mounted using a locking nut supplied.

Other Brownell stories
-
Brownell develops high-pressure purging system
Brownell has developed a high-pressure purging system that removes moisture and reduces the humidity within tyres to a known dryness condition. -
Brownell has High Flow Performance Relief Valves
Brownell has introduced a range of Ultra High Flow Performance Relief Valves with standard sizes of 25 to 200mm. -
Relative humidity indicators handle diverse levels
Relative humidity indicators can provide an indication of when the desiccant is saturated and requires replacement or recharging. -
Gas purging system simplifies humidity control
Brownell dry gas purging safeguards products ranging from electronics, switchgear and workstations to storage containers, underwater equipment and double glazing cavities. -
Valves offer relief from pressure differentials
Ideal for applications where a negative pressure of just a few millibars could result in permanent damage.
