Breathers (Spin-on & Desiccant)

Spin-on Breathers
Adaptors and Disposable Breathers

Fluid contamination is the root cause of

most hydraulic system failures.
Controlling contamination in the air a
system breathes is critical. The synergy
of Hy-Pro fluid filter elements and Hy-Pro
Spin-on breathers yields clean fluid and
a healthy hydraulic system.

HPBR-102 FOR MOBILE AND HEAVY DUTY APPLICATIONS B

*HPBR-102 assembly is complete with a metal reinforced base, that remains with the
reservoir or gearbox, and a replacement breather cartridge (HPB-302) threaded into
the base. Upon indication remove the cartridge only (HPB-302) and replace with a
new cartridge. The HPBR-102 assembly is recommended for Heavy Duty,
Continuous vibration, Mobile, and Extreme climate applications.
HPBR-102 has a 1” Male NPT connection.

WHEN TO CHANGE THE HY-DRY BREATHER

New Hy-Dry breather silica is gold and as the

silica adsorbs water the color will change to
green and then to a very dark green (near black).

RESERVOIR ADAPTORS

Adaptors are available to retrofit any reservoir or gearbox to accept the Hy-Dry breather. HPB-100 through HPB-102 will
require one of the adaptors displayed below. HPB-108 through HPBR-102 do not require adaptors.
