Dollinger AI-128-V Two Stage

The Need
Contaminants at the intake of compressors, blowers and turbines dramatically affect the cost of supplying compressed air.

Inefficient intake filtration permits contaminants to corrode, erode and foul internals, effecting a reduction in performance and component service life. Contamination increases repair, maintenance and downtime of rotating equipment. Contaminants not effectively removed by the air intake filter will also migrate downstream in compressed air piping, to system controls, instrumentation, tools and other production processes.

Manufacturing facilities worldwide are experiencing escalating maintenance costs, increasing at an average rate of 10% to 17% annually. These increases are in addition to the related costs associated with downtime, rejects and rework of production process.

For “world class” competitiveness, today’s industrial strategies must include management of the high cost of process intake contamination.

Housing Design and Construction
The rigid, all weather galvannealed housing of the AI-128-V provides strength and corrosion resistant protection on outdoor installations. All surfaces are finished with a coat of blue hammertone enamel for long life and durability. Weatherhoods are provided as standard equipment.All metal joints of the AI-128-V are welded and caulked as required to prevent dust from entering the unit. The standard conical safety screen over the filter outlet prevents small foreign objects from entering the exposed air intake passage when servicing or replacing panel elements. A ¼” pressure tap attachment is standard on each housing for ease of installation.

Silencing for reduction of air and equipment noise is standard on the AI-128-V, providing sound attenuation up to 17.5 dB(A). The filter housing may also be modified or customized to meet special application needs.

Element Design and Construction
Prefilter Element
The primary panel element incorporates a pleated media design which provides optimum filtration area with minimum pressure loss and large dirt holding capacity. An electrogalvanized steel frame and synthetic fiber filter medium combine to make the element cleanable and reusable. A rugged metal frame and wire mesh guards on the element face provide added durability and ensure against rough handling and moisture.

Each panel element of the AI-128-V can handle flow rates of 3000 SCFM and provide 99% retention efficiency of 10 microns. After extended use, the elements may be cleaned with a mild detergent solution.

The prefilter may be washed by low pressure water hose (<30 psi), properly dried and reused with good results

Final Stage Element
The final stage TURBO KLEENT multiple Vee panel designs place eight (8) panels in a “Vee Formation” within a nominal 24″ x 24″ x 11 – ½ ” standard size.

A proprietary water resistant microglass media presents a “dual-layer” barrier to particles which penetrate the prefilters.

An extruded polymeric frame encases the eight (8) panels which are totally sealed in the TURBO KLEENT.

The Features and Benefits of Dollinger AI-128-V Two Stage are:
Superior Performance
99.97% removal at 2 microns and over 90% removal at 0.4 microns to protect the performance and life of rotating equipment.

Extended Element Life
More available surface area with the TURBO KLEEN T design doubles dirt holding capability, extending element life and reducing element replacement costs.

Sizing Flexibility
The TURBO KLEENT is capable of flowing up to 3000 SCFM rather than the standard 2500 SCFM. That is a 20% increase in capacity without penalty of added pressure drop. This sizing flexibility allows for a smaller housing and lower first cost.
