Applications: Designed for both mobile and stationary reservoir breather applications

Obieg hydrauliczny Donaldson
Breather A good working hydraulic system starts with a clean hydraulic fluid reservoir. Donaldson T.R.A.P.™ breathers are the only breathers on the market that literally strip moisture vapor from intake air and expel the moisture back to the atmosphere on the outflow cycle. The filter continuously regenerates its water holding capacity and keeps your hydraulic reservoir clean.
In-Tank Filter Donaldson in-tank filtration solutions for hydraulic reservoirs are economical, space-saving units that offer a variety of options including aluminum or plastic access covers, mounting option, breathers and accessories. Strong, durable die-cast aluminum head and a steel or plastic canister construction for heavy-duty applications.
Medium Pressure Filters Donaldson medium pressure hydraulic filters proof it’s leading position in the hydraulic filtration market. These filters are built to keep hydraulic components protected under all conditions. Large global original equipment manufacturers (OEM) rely on Donaldson’s experise and knowledge to protect precious hydraulic equiment and parts.
High Pressure Filters Uncompromised protection for your equipment and parts. These hard worling filters protect sensitive components in high pressure hydraulic systems. They operate in tough environments and support working pressures up to 300 bar. Meeting or exceeding the original equipment manufacturer (OEM) specifications, these filters are designed and equiped to keep the hydraulic system protected under all conditions.
Low Pressure Filters Donaldson hydraulic filters – Uncompromised protection for your equipment and parts. The low pressure hydraulic filters are protecting the hydraulic system and pump to allow smooth transition and effective pressure build-up. Meeting or exceeding the OEM’s specifications, these filters are designed and equiped to keep the hydraulic system protected under all conditions.
