Pressurised breathers can reduce breathing by as much as 90% to 95%, increasing the life of the breather by a factor of 10. They are recommended for systems that are expected to operate in extremely dusty environments. Operates similar to a conventional breather except it incorporates a relief valve set at 5 or 10 psi and a vacuum breaker. When the level first falls, air enters the reservoir through the vacuum breaker and filter. When the level rises, air is compressed rather than being expelled. Therefore, changing fluid levels are accommodated by the changing size of the air bubble in the reservoir, instead of breathing to atmosphere.
