ENERGY EFFICIENCY
ANY RESTRICTION TO AIRFLOW WITHIN A FILTER HOUSING / ELEMENT WILL REDUCE THE SYSTEM
PRESSURE. TO GENERATE COMPRESSED AIR, LARGE AMOUNTS OF ELECTRICAL ENERGY IS REQUIRED,
THEREFORE ANY PRESSURE LOST WITHIN THE SYSTEM CAN BE DIRECTLY CONVERTED INTO A COST FOR
WASTED ENERGY. THE HIGHER THE PRESSURE LOSS, THE HIGHER THE ENERGY COSTS.
Pressure loss in a compressed air filter is a combination of fixed pressure losses and incremental pressure losses. Fixed pressurelosses come from the filter housing and the interface between the filter housing and filter element. Incremental pressure lossescome from the filter element as it blocks up with contamination during operation. Inmost filters, high operational costs are generally due to a poorly designed airflow path within the filter housing and element andpoorly selected filtration media. In addition to this, the high differential pressure change points recommended by many filtermanufacturers increase operational costs even further.

Providing an optimal flow

path for the compressed air

is key to reducing system

operating costs.

“Bell mouth” housing inlet
&full flow inlet conduit
OIL-X EVOLUTION filter housings feature
a"Bell Mouth" inlet to provide a smooth, turbulent
free transition for the air as it enters into the filter
element without restriction through the full flow
element inlet conduit.
Smooth 90° elbow &
aerospaceturning vanes
Flow distributor Filter models 015 to055 include an upper flow
distributor and all models include a lower conical
flow diffuser.
The upper flow distributor provides turbulent free
distribution of the air flow throughout the filter
element ensuring full utilisation of all available
filtration media, increasing filtration performance
and reducing energy consumption.
The combination of conical flow diffuser and a
drainage layer wrapped under the lower endcap
allows airflow through the lowest section of the
element, which is not possible on conventional filters
due tothe position of the "wet band".
Specialistmedia
treatment
OIL-X EVOLUTION uses a specialist
treatment for it’s filter media which
actively repels oil and water,
preventing the fibres of the media
from soaking up liquid. This ensures
coalesced liquids do not reduce the
high voids volume of the filter media,
therefore reducing system pressure
losses and energy consumption.

AEROSPACE FLOW MANAGEMENT SYSTEM

Deep bed
pleating
Deep bed pleating of the filter
media reduces the air flow velocity
within the media, which in addition
toimproving the filtration
performance of the element,
significantlyreduces pressure
losses and energy consumption.
In aerodynamic terms, a design which turns the air sharply
through 90°is known as an inefficient corner. This typically
has always been the method used to direct air into a
compressed air filter element.
OIL-X EVOLUTION uses a smooth 90°elbow to direct air
intothe filter element, reducing turbulenceand pressure
losses significantly by turning the inefficient, sharp 90°
corner into an efficient one.
As the diameter for the conduit increases, the benefits are
reduced, therefore filter models 025 to 055 also include
aerospaceturning vanes which channels the air through a
number of smaller, more efficient corners, reducing
pressure loss and energy consumption even further.
