High Efficiency Rigid Filter

HIGH-EFFICIENCY FILTRATION WITH PLASTIC FRAME

High Efficiency Rigid Filter (Plastic Frame)

High efficiency rigid filter combines a large glass-fiber filtration area with a lightweight and rigid polystyrene frame. It provides compact final-stage air filtration for HVAC equipment, air handling units and cleanroom ventilation systems. Available efficiency classes include E10, E11, E12, H13 and H14.

The polystyrene frame reduces overall weight and removes the need for a metal outer frame. Meanwhile, mini-pleated glass-fiber media and hot-melt separators create a large filtration surface within compact dimensions. A two-component polyurethane compound seals the filter pack to the frame.

Rigid Filter Construction with Plastic Frame

First, the mini-pleated glass-fiber media creates a large filtration area. Hot-melt separators maintain regular spacing between the pleats. As a result, airflow can spread more evenly across the filter surface.

The polystyrene frame offers low weight and good corrosion resistance. Therefore, installation and filter replacement become easier. In addition, the plastic body helps avoid surface oxidation associated with metal frames in humid environments.

The product group uses a 130 mm filter depth and a 25 mm flange. Several surface-protection and gasket options are available. Standard dimensions include 287 × 287 mm, 287 × 592 mm and 592 × 592 mm.

Filter Selection and Application Process

Filter Class

First, select E10, E11, E12, H13 or H14 according to the required particle efficiency and process conditions.

Airflow Check

Next, compare the actual airflow per filter with nominal airflow and initial differential pressure.

Gasket Selection

Then, select poured, EPDM or gray EPDM gaskets according to the housing and sealing surface.

Installation and Check

Finally, check the housing, flange, gasket contact, clamping mechanism and differential pressure after installation.

Filter Selection Criteria

Filter ClassChoose E10–H14 according to the required particle efficiency and clean-area requirements.

Nominal AirflowCompare actual airflow per filter with the nominal airflow in the model table.

Filter DimensionsWidth, height and the 130 mm depth must match the existing filter housing.

FlangeCheck compatibility of the 25 mm flange with the housing and clamping mechanism.

Gasket TypeSelect poured or EPDM gaskets according to the contact surface and airflow direction.

System PressureCheck initial pressure drop together with available fan pressure and energy consumption.

Maintenance and Replacement

First, monitor differential pressure across the filter regularly. During periodic maintenance, inspect the plastic frame, filter media, surface protection and gasket. Also verify correct seating inside the filter housing.

The recommended final pressure drop is approximately twice the clean-filter value. However, it should not exceed 600 Pa. In addition, consider air quality, fan energy consumption and process conditions when planning replacement.

Do not wash the glass-fiber media or clean it with compressed air. Likewise, avoid mechanical impact on the filter pack. Do not expose the plastic frame to excessive temperature or incompatible chemicals.

Technical Application Note

The filtration area, nominal airflow and initial differential pressure shown in the table refer to standard product conditions. Actual performance can vary with installation, housing leakage, airflow, system pressure, filter face velocity, test conditions, instrument calibration, dust load, humidity, temperature, filter loading and airflow distribution. Therefore, define individual testing and certification requirements for H13 and H14 filters before ordering.
