Four decades
of experience in designing and manufacturing crankcase-emission
filtration systems have made Metex the supplier of choice for
all types of consumer- and commercial-vehicle applications, both
on- and off-highway.
Due to our unique ability to manufacture
Breather Elements and Assemblies from a wide range of ferrous
and nonferrous
metals, engineered plastics, and composites, Metex emission-control
solutions can also be found in equipment designed for use in
corrosive and high-temperature environments—such as
marine engines as well as consumer and industrial generators
and compressors.
In
addition, Metex Breather Elements can be made from any material
that can be formed into wire—allowing immediate
changes in key performance criteria for even the most demanding
applications.
Metex designed and manufactured Breather Elements
and Assemblies provide long-lasting performance in
reducing crankcase emissions
as well as oil consumption and oil pooling on external
engine and vehicle parts—while protecting air-intake products
in closed-crankcase ventilation (CCV) systems.
Custom engineered
to enhance engine performance and reliability
Metex engine-filtration solutions are custom designed for enhanced
performance in both open-crankcase and closed-crankcase ventilation
systems, as either internal or external devices. Internal devices
use baffles (which only remove particles of 5µm or larger)
or coalescing filter elements in the cylinder head cover or other
locations inside the engine.
External crankcase filtration systems
consist of a breather assembly or mechanical device secured directly
on the engine
or by remote, bracket-mounting. Unlike other systems, Metex
Breather Elements and Assemblies are designed to remove both fine and
coarse particles, as well as fine oil-mist condensation.
In open-crankcase
ventilation systems Metex helps reduce engine oil consumption, the threat of
catastrophic engine failure due
to oil loss in engines in remote locations, and invalid warranty
claims due to deposition of oil on engine and other vehicle
parts. They also help eliminate accumulation of oil mist on test-cell
equipment.
In closed-crankcase systems, specifying the right
Metex Breather Element or Assembly can help reduce warranty service levels due
to pooling of lubrication oil in the crankcase pressure control
valve, as well as turbocharger intake compressor and intercooler.
Metex custom products also reduce the formation of an oil film
within the heat exchanger or the aftercooler or intercoolers
on certain turbo-charged engines.
| BENEFITS |

to 650°C, depending upon material selection
- High separation
efficiencies of 95-99% and low pressure drop
- Can vary element density and surface area to solve the most difficult
separation problems
- Can accommodate any available engine space
- Easy to install in existing or new cavities or housings
- Ability to combine monofilament or multifilament material into one breather
element
- Element can be die formed, layered, or spiral wound
- Better, more cost-effective solutions for reducing crankcase emissions

Reduced Crankcase Emissions & OEM Costs
Metex has the material-science knowledge, as well as design-engineering and
manufacturing expertise, to supply breather elements and assemblies in
any size and for any type of engine—with blow-by levels ranging from
0.2-40 cubic feet per minute.
In-house Testing Capabilities and Equipment
Metex uses the very latest test equipment and procedures to optimize the design
of each Breather Element and Assembly. Variables such as flow rate, temperatures
and pressure drop can all be measured and controlled in our custom-designed
laboratory.
From initial inquiry, through prototype development, to low- and high-volume
production, you can count on our decades of experience to deliver solutions
that solve the most challenging crankcase-emission problems.
