Produkteinführung

This two-stage assembly combines a 2, 4 or 6 in prefilter track with a downstream full-depth HEPA section. The coarse stage captures larger dust before it loads the expensive final element, reducing premature HEPA resistance and extending useful service. A fully welded side-access cabinet keeps both filters in one coordinated pressure boundary while allowing each stage to follow a different replacement trigger.

Key Features

HEPA life protection

The first stage removes coarse loading before it reaches the high-efficiency final filter.

Selectable prefilter depth

Two-, four- and six-inch tracks support different capacity and resistance targets.

Integrated service section

Matched doors and filter tracks keep both stages accessible within one modular housing train.

Applications

For medical and clean-manufacturing air handlers that need dependable final HEPA filtration and a replaceable dust-loading stage upstream.

Solutions for Your Application

Both filters are replaced together even though only the prefilter is loaded.Monitor stage pressure separately and change each element according to its own resistance or integrity criterion.

A high-resistance prefilter consumes too much of the fan allowance.Choose the prefilter depth and efficiency from dust load, service interval and available total static rather than capacity alone.

Verfügbare Optionen

Confirm prefilter grade and depth, HEPA size, cabinet material, access side, individual pressure taps, test ports and duct connections.
