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,
T
HEREFORE 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.
P
ressure loss in a compressed air filter is a combination of fixed pressure losses and incremental pressure losses. Fixed pressure
losses come from the filter housing and the interface between the filter housing and filter element. Incremental pressure losses
come from the filter element as it blocks up with contamination during operation.
I
n most filters, high operational costs are generally due to a poorly designed airflow path within the filter housing and element and
poorly selected filtration media. In addition to this, the high differential pressure change points recommended by many filter
manufacturers increase operational costs even further.
Pr
oviding an optimal flow
path for the compressed air
is key to reducing system
operating costs.

IL-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

lement without restriction through the full flow
element inlet conduit.

Flow distributor
Filter models 015 to 055 include an upper flo
w
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 ener
gy consumption.
The combination of conical flow diffuser and a
dr
ainage layer wrapped under the lower endcap
allows airflow through the lowest section of the
element, which is not possible on conventional filters
due t
o the position of the "w
et band".

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
into the filter element, reducing turbulence and 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
aerospace turning vanes which channels the air through a
number of smaller, more efficient corners, reducing
pressure loss and energy consumption even further.
