AI
- 104 Single Stage Filter Housing
The Dollinger AI-104 is one of the
most efficient air intake filters on the market. Developed
to meet a variety of air filtration requirements for all
types of engines, compressors and blowers, it has low initial
pressure drop and high dirt holding capacity.
The
AI-104 is designed to mount upright, either directly on
the machinery inlet, or on remote air intake piping. Dollinger
provides 31 standard models, with capacities up to 20,000
scfm and outlet sizes from 1/2-inch to 24-inch plate flange
(matches diameter and drilling for 150# ANSI standard.
Housing
Design and Construction
All AI-104 models are manufactured of enameled carbon steel
which provides strength and long-life protection from snow
and rain on outdoor installations. This rugged housing construction
eliminates the need for louvers or separate weatherhoods.
There is no need for special foundations or structural supports
because all models mount directly on the machinery or remote
air intake piping. The filter housing may also be modified
or customized to meet special application needs.
Element
Design and Construction
The AI-104 incorporates an efficient replaceable, cleanable
radial-fin element. The pleated or "radial-fin"
design provides a more compact, lighter-weight filter assembly
with greater dirt holding capacity. This ensures minimum
pressure drop, the largest filtering area for a given element
size, long filter life and efficient filtration. Our standard
elements are manufactured with a special durable felt medium
having a contaminant removable efficiency of 98% of all
particles 10 microns and larger. When required, we can provide
special media of synthetic fibers or woven glass which provides
a wide range of efficiencies. Standard elements are furnished
with a carbon steel center core and galvanized steel wire
mesh support frame. Stainless steel materials are also available.
Sewn
or Molded-End Filter Elements
The sewn-end element on models AI-104-590-080 and larger
feature sewn construction. This unique feature prevents
leakage of unfiltered air past the element. Following several
field cleanings, this sewn-end style can be returned to
our factory for recovery and reconditioning. Here, the element
frame is stripped of medium, inspected for mechanical integrity,
wire brushed, sand blasted, degreased, repaired (if necessary),
and covered with new filter medium. It is then packaged
and promptly returned - good as new at a substantial cost
saving.
The
molded-end element used on models up to AI-104-440-080 provides
positive gasket sealing to prevent leakage of unfiltered
air. The element is manufactured of a special durable felted
medium, removing 98% of all particles 10 microns and larger.
If required, Dollinger can provide special media of synthetic
fibers or woven glass which provide a range of efficiencies.
