Liquid Filtration Performance

When you are looking for improved performance, look
for Donaldson lube, fuel, coolant and hydraulic filters
with synthetic media – they are easy to spot; they carry
our Synteq brand name!

Synteq for Lube Filtration

When an application requires higher efficiency filtration
than cellulose filter media can deliver, we use Synteq.
Synteq media captures more and smaller contaminant than When changing any filter that has a gasket —

A compression seal is a means of preventing
migration of liquids, gases or solid contaminates
across a joint or opening in an assembly or
housing. A seal not only prevents the escape of
fluid from inside and foreign material from entering
the system from outside, but it must provide for easy
installation and removal. A new gasket is critical for

Synteq's double-layered media has increased
particulate holding capacity and is a high performance
water separator. It has the ability for high efficiency
emulsified water separation and can be used in both
the suction and pressure sides of fuel systems. The
polyester layer provides improved water separation
and dirt holding capacity performance, making it an
ideal choice for critical applications or extended
service intervals.
