Breathers take the pressure out of enclosures
A
Brownell product story
Edited by the Engineeringtalk editorial team
Apr 24, 2008
Miniature immersion-proof breathers allow equipment to breath but prevent water and dust ingress in corrosive and hostile conditions.
Brownell has developed a range of miniature immersion-proof breathers that will eliminate pressure build-up from heat within electronic product enclosures.
Unchecked, such pressures can otherwise fracture lightweight housing materials.
The breathers allow equipment to breath but prevent water and dust ingress in corrosive and hostile conditions.
Made in plastic and metal able to suit aggressive and high- or low-temperature environments, these breathers solve the electronic equipment design dilemma of either restricting applications or increasing enclosure strength.
They can withstand driving rain or even total immersion in water for long periods.
Simply screwed in place or mounted using a locking nut supplied, units can pass high flow rates of air resulting from rapid changes in temperatures and pressure.
They may be fitted to desiccant tubes to remove moisture and other contaminates including hydrocarbon vapours.

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.
